Compact Hardware 1 At a Glance Introduction The information in this chapter introduces the Compact Controller and describes the common architecture shared by the 984 Controllers. If the Compact Controller is new to you, please refer to Getting Started, p. 145).
Hardware The 984 Family of PLCs Common 984 Controller Architecture 12 Modicon’s Compact Programmable Controllers bring the high performance, application flexibility, and programming compatibility of the 984 family to the small controller market. As a controller in the 984 family, Compacts implement a common instruction set for developing user logic, standard Modbus communication functionality, and optional Modbus Plus communication capabilities.
Hardware The following figure shows the 984 PLC architecture.
Hardware Special Features of the Compacts CPU Memory Choices 14 The Compact Controllers deliver 984 architectural consistency and performance in a small, modular package. Compacts are easy to install, require only a small area for installation, and support the low-cost line of A120 I/O modules. The E984-258/ 265/275/285 PLCs feature 386 EX processors for increased performance and operate using Concept programming panel software.
Hardware l The E984-275 CPU with two Modbus communication ports and a Modbus Plus network interface, 1 Meg FLASH RAM based system executive, 512K SRAM, 16K words of user memory, 32K words-State RAM, 48K words total, 128K words of configurable SDA 6X registers, 25Mhz CPU operation, and PCMCIA release 2.1 type II socket supported.
Hardware Memory l User memory is the amount of memory available for your user logic program (one word comprises 16 bits). l State RAM memory is used to hold register and discrete inputs and outputs and internal data storage. State RAM is allocated to the four different reference types (0xxxx, 1xxxx, 3xxxx, and 4xxxx). (See System Capacity, p. 18). l Memory Partition Option with Concept 2.1. When using the E984-258/265/275/ 285 PLC with Concept 2.1 or higher you may partition the total SRAM memory.
Hardware This is the example table.
Hardware System Capacity The system capacity for the PLCs are described below. This is the system capacity table. PLC Total User Memory Total State RAM Max. I/O Max. 0xxxx Capacity type State per RAM System 120 1.5k 2k 130 4k 2k 131 4k 2k 141 8k 2k 145 8k 2k 241 8k 2k 245 8k 2k 251 16k (24K Extended Memory) 2k 256 max.
Hardware Note: For the A984-120/13x/14x and E984-24x/251/255 models. The listed values (in the table). See System Capacity, p. 18 for discrete (0xxxx, 1xxxx) and register (3xxxx, 4xxxx) types represent maximum allowable. To maximize one type you minimize the other three types. Other than these limits the allocation between data types is flexible. This type of trade off between reference types does NOT apply to the E984-258/265/275/285 models.
Hardware PCMCIA (E984275/285 Only) The E984-275/285 CPUs support PCMCIA release 2.1 type II socket. The CPU provides routines for accessing the PCMCIA card. Drivers are included to support additional memory via AMD compatible memory cards. The card may be used to store your application or as dynamic storage for data. You may write and read your applications to either FLASH or PCMCIA card. You may use the PCMCIA card for data logging from the user program via the DLOG instruction.
Hardware When downloading a new executive to your PLC you MUST disable the PLC password (via Concept) unless the PLC is stopped in a stop with error state. Under this condition the Concept executive loader works. When a login password is lost, you can gain access by using the following procedure: Push the Memory Protection switch up to the Mem Prot position. Remove the Lithium battery from the PLC. Cycle the power to the PLC.
Hardware Secured Data Area (SDA) (E984-258/265/ 275/285 Only) This feature allows you to configure an area in RAM that is secured from being overwritten. Secured Data Area (SDA) is a block of the Compact PLCs RAM that is set aside as 6x data space. The SDA can only be written to by specific functions that require secured data storage (Gas Flow Calculation Audit Trails, etc.). General purpose Modbus commands, built-ins, and loadables can NOT write to the SDA.
Hardware A120 I/O Support The Compact Controllers work with Modicon’s A120 Series of low-cost I/O modules. A120 modules are available in densities of four, eight, and sixteen discrete I/O points; eight analog input channels; and two, four, and eight analog output channels. In addition, speciality modules for positioning, servo control, simulators and filler modules are available.
Hardware The A984-120/130 PLCs A984-120/130 Front Panel These two models have identically designed front panels, with one Modbus communications interface, an EEPROM auxiliary memory socket, two slide switches for memory protection and communication parameter selection, four LED indicators, and a terminal strip for 24 Vdc power. l The A984-120 (Compact Controller comes with 1 Modbus communication port, 2K state RAM, 1.5K words of user memory, 8Mhz CPU, and operating temperature 0 ... 60 degrees C).
Hardware Memory Protect The memory protect switch is the top switch; it serves two purposes: l If on, it prevents a programming panel from overwriting the configuration or user logic l If off, it allows configuration and user logic changes. It also determines whether or not the controller should read the configuration and user logic from an EEPROM auxiliary memory card inserted in the EEPROM socket. This occurs only at power-up. This is the mem prot switch.
Hardware LED Indicators The following table lists the LED indicators and their meaning. LED Indicator Meaning Ready (amber) Controller has passed power-up diagnostics- LED is ON in unconfigured, stopped, and run states as long as health status is valid; is OFF when error condition detected by diagnostics.

Hardware PLC Interrupt Connection One two-position connection is located on the front of the CPU. It is used to connect to the 470 GPS 001 00 Receiver for the time synchronization of the PLCs TOD clock.(See Time Synchronization of the TOD (E984-258/265/275/285 Only), p. 22.) LED Indicators The following table shows the LED indicators and their purpose.
Hardware EEPROM Auxiliary Memory Capability (A984-1xx/E984-24x/251/255 Only) Auxiliary Memory Socket The A984-1xx, E984-24x/251/255 Controllers contain an auxiliary memory socket for a credit card-sized EEPROM card on which system configuration and user logic can be saved. System configuration and user logic data can be written to an EEPROM card and used to back up the program stored in battery-backed RAM. This is the socket location.
Hardware CAUTION Do not insert EPROM card if controller is ON. An EEPROM card must be inserted into or removed from the socket only when the controller is OFF. Insertion or removal while the controller is powered up can damage the EEPROM card. Failure to observe this precaution can result in injury or equipment damage. Writing to EEPROM Auxiliary Memory Using either Modsoft or Modsoft Lite programming software, you may write the configuration and user logic to the EEPROM card.
Hardware Reading EEPROM System Data Data are read from an EEPROM card as part of the power-up sequence. If the controller determines that a card is present in the socket, it checks the state of the memory protect slide switch. l If the switch is OFF, the controller tries to read the data l If the switch is ON, the controller ignores the presence of the card.
Hardware Editing Logic Loaded from EEPROM Card (A984-1xx, E984-24x/251/255 Only) Editing Logic From EEPROM Card An A984-1xx or an E984-24x/25x Controller loaded from an EEPROM card is brought up in OPTIMIZED mode-i.e.; that is, either in RUN or STOPPED mode (depending on the controller’s previous operating state) but not in EDIT mode. EDIT mode is required for programming the controller. To modify the newly loaded logic, you must move the controller out of OPTIMIZED mode and into the Ladder Logic area.
Hardware Editing Procedure If Controller Has No Battery 890 USE 108 00 August 2001 Follow these steps if the controller has no battery. Step Action 1 Insert the EEPROM card with the desired logic into the slot in the controller, then power up the unit. The controller should come up in OPTIMIZED mode with the EEPROM logic and configuration data loaded. 2 Using Transfer in your panel software, upload the logic program to the programming panel. 3 Power down the controller.
Hardware Program Storage using FLASH RAM & PCMCIA (E984-258/265/275/285 Only) Program Storage Overview The E984-258/265/275/285 PLCs feature 1 megabyte of internal FLASH RAM. 480 kilobytes are available for application storage. The remaining area is reserved for kernel, executive, and special code use. In addition, the E984-275/285 PLCs have a PCMCIA auxiliary memory socket for storage. The E984-275/285 PLCs supports industry standard memory size PCMCIA cards up to 4 megabytes.
Hardware Storing to the PCMCIA or Internal FLASH Card Save to FLASH stores information to the PCMCIA or internal FLASH card. The following table describes the options that are available from the Save to Flash screen. When the save to FLASH is performed, the configuration, IEC and 984 LL are all stored to the PCMCIA card or internal FLASH depending on your selection. Option Description Internal Stores, RAM information to the internal on board FLASH of the PLC.
Hardware PCMCIA Operations and PLC Power Up Reading the PCMCIA/FLASH RAM data is performed automatically. The following table describes the PLC power up state in relation to PCMCIA loading. FLASH RAM or PCMCIA Card PLC MEM Switch Concept Dialog Result Application present Not configured Off If Dialog box was checked, it starts after download. Application is loaded from the PCMCIA card to the RAM of the PLC and the PLC starts running automatically.
Hardware PCMCIA LED Error Conditions If any the error conditions listed in the following table occurs, the loading of an application to the PLCs memory is terminated, and the PC LED (PCMCIA) blinks indicating the specific error detected. Note: Remember that only the E984-275/285 have a PC LED (PCMCIA).

Software Support 2 At a Glance Introduction This chapter describes the software packages that support the Compact family. All of the elements of the Compact PLC instruction set are listed.
Software Panel Software Support Overview The Compact Controllers may be configured, I/O Mapped, and programmed using Concept panel software, full-feature Modsoft panel software, or Modsoft Lite (depending upon the model). All of these software packages can be installed on the Modicon P230, an IBM-AT, or a compatible computer. The programming and configuration editors used for Compact are similar to those used for other 984s; special I/O Map screens have been designed for A120 I/O modules.
Software Modsoft Lite (A984-1xx, E98424x/251/255 Only) Modsoft Lite (371SPU921000) is provided on 3.5 inch diskettes. Standard panel software packages include the editors listed in the following table. Editor Description Configurator Defines controller and communication parameters, allocates memory, accesses controller operations and specials (e.g., battery coil register, timer register, and time-of-day clock) I/O Map Links discrete and register reference numbers to modules in the I/O subsystems.
Software Sequential Function Charting SFC is especially suitable for sequential processes because it allows you to generate programs that are organized in steps (rather than in linear ladder logic sequence). A sequential function chart can solve multiple networks in a parallel link or one in a choice of several networks in a selective link. Logic is solved within a block until a specified transition event informs the CPU to move to the next step.
Software The Compact Instruction Set Overview The Compact instruction set is dependent on the Compact model: l The A984-1xx, E984-24x/251/255 supports 984 ladder logic only. In contrast, the E984-258/265/275/285 supports 984 ladder logic and IEC 1131-3. l The specific instructions listed below are available for the A984-1xx, E984-24x/ 251/255, and E984-258/265/275/285 models as noted.
Software 984 Ladder Logic Instruction Set The three tables that follow list, in detail, all of the ladder logic programming instructions used by Compact. The following table describes the Counters, Timers, (Two Nodes); Calculations, and Other Math (Three Nodes) instructions in the Compact Instruction set.
Software The following table describes the DX Moves (Three Nodes), DX Matrix (Three Nodes), and Skip Node (One Node) instructions in the Compact Instruction set. 890 USE 108 00 August 2001 Instruction Description DX Moves R"T (Three-Nodes) T"R Moves register values to a table Moves table values to only one register.
Software Instruction DX Matrix (Three-Nodes) Skip-Node (One-Node) 56 Description AND Logically ANDs two matrices OR Does logical inclusive OR of two matrices XOR Does logical exclusive OR of two matrices COMP Performs the logical complement of values in a matrix CMPR Logically compares the values in two matrices NOBT Senses the logic state of a bit in a register. The bit represents an N.O. contact. E984-258/265/275/285 only NCBT Senses the logic state of a bit in a register.
Software The following table describes Process Control Function Library (PCFL) (ThreeNodes) and the Ladder Logic Subroutine Instructions in the Compact Instruction set. Instruction Description Process Control AIN Function Library (PCFL) AOUT (Three-Nodes) ALARM Scales raw analog input into engineering units for calculations. E984-258/265/275/285 only Ladder Logic Subroutine Instructions (Two-Nodes) Calculates signals for analog output modules.

Software Compact Loadable Software Instructions You can add loadable instructions to the resident instruction set. The following table describes the loadable software instructions that are available for Compact. Three-Nodes FNxx Allows you to develop your own custom loadable function blocks. Modicon part number SW-AP98-GDA. DRUM Simplifies implementation of sequential step-oriented logic. and ICMP Modicon part number SW-AP98-SxA.
Software XMWT AND XMRD Function Blocks (E984251/255 Only) The Extended Memory function blocks XMWT and XMRD function as described in the Modicon Ladder Logic Block Library User Guide (840 USE 101 00) with two exceptions, as noted below. The functions are available from the panel DX selection when E984-251/255 is configured l The bottom input is ignored because the E984-251/255 can not detect memory errors as it reads or writes to the extended memory.
Software The extended memory Modbus read and write functions are described in the Modbus Protocol Reference Guide (PI-MBUS-300) as Read/Write General Reference function codes 20 and 21. The only difference in the E984-251/255 extra register implementation is the size of the extended memory, which changes the number of files and the number of registers. The following table show the E984-251/255 extra register implementation.
Software SAVE Instruction Block (E984-258/265/ 275/285 Only) The SAVE block saves a block of 4x registers to state RAM. State RAM protects the registers from unauthorized modification. l The size is three nodes l The PLC compatibility is PC-E984-258, PC-E984-265, PC-E984-275, and PCE984-285. l The opcode is 54 hex The following figure shows the block structure of the SAVE block.
Software LOAD Instruction Block (E984-258/265/ 275/285 Only) The LOAD block loads a block of 4x registers (previously saved) from state RAM where they are protected from unauthorized modification. l The size is three nodes high l The PLC compatibility is PC-E984-258, PC-E984-265, PC-E984-275, and PCE984-285. l The opcode is 55 hex The following figure shows the block structure of the LOAD block.
Software Description of the DLOG Instruction Block (E984-275/285 Only) The DLOG (data logging) block allows state RAM data to be recorded into the memory of a PCMCIA card using ladder logic. Note: Each segment in the PCMCIA card MUST be erased before any locations, in the segment, are written, this is necessary because the PCMCIA driver does not allow 0 bits in the card to be changed to 1 bits via a write command. Only an erase can make this change.
Software Representation The following information describes the representation of the DLOG instruction block. The following figure represents the block structure. Enable DLOG operation control block Terminate active DLOG operation data area DLOG Operation is active DLOG Error Operation successful length The following list provides detailed information about inputs to, outputs from, sand the node content of DLOG.

Refer to Schneider Automation’s Modbus Plus Network Planning and Installation Guide (890 USE 100 00).
Communication Capabiliites Modbus Plus Capabilities for Compact Overview of Modbus Plus Modbus Plus is a local area network designed for industrial control applications. It enables the A984-145, E984-245/255/265/275/285 Controllers to become a node on the network and to communicate with other 984 controllers, host computers, and special bridge and multiplexer devices. A network may comprise one or more communication sections. One section can support up to 32 nodes. Up to 64 nodes can exist on a network.
Communication Capabiliites Multiple Modbus Plus networks can be interconnected using a BP85 Bridge Plus device. The following figure shows multiple networks linked by Bridge Plus. Network A (Up to 64 Nodes) Node 5 Node Node 6 Node 8 Node Node Node 7 BP85 Network B (Up to 64 Nodes) Node 3 Node Node 4 Node Node 5 Node 6 Node = Terminating Connector = Inline Connector Each node within a network must have a unique address number in the range 1 ... 64.
Communication Capabiliites How the A984145, E984-245/ 255/265/275/285 Initiates Modbus Plus Transactions A984-145 (or any programmable controller with Modbus Plus capability) may initiate network communication using a ladder logic function called MSTR. MSTR allows you to specify the type of communications transaction you want to carry out and to define the routing path over which you wish the transaction to take place.
Communication Capabiliites Bridge Mode Between Modbus and Modbus Plus Selecting Standard or Bridge Communications The standard Modbus port on the A984-145, E984-245/255/265/275/285 Controllers can be used in either of these two ways: l as a slave port to a Modbus master device l as a bridge between a Modbus master device and the Modbus Plus network nodes Make the above selection by setting the communication parameter slide switch as follows: l setting the communication parameter slide switch (the bottom s
Communication Capabiliites Modbus Master Device Connections If a Modbus master device is connected to the Modbus port while the A984-145, E984-245/255/265/275/285 is in bridge mode, the master device can be attached to the local controller or to any other node on Modbus Plus. l If you attach to the local controller, messages from the Modbus master are sent directly to the local A984-145, E984-245/255/265/275/285 without being routed over a Modbus Plus communication path.
Communication Capabiliites Addressing Ranges on Modbus Plus 890 USE 108 00 August 2001 A single Modbus Plus network can have up to 64 addressable nodes, each with a unique address in the range 1 ... 64. (See Modbus Plus Communications A984-145, E984-245/255, p. 80 for more information about address settings). The Modbus master device connected to the Modbus port can attach to any node using direct attach address routing, simply by specifying the correct address in the range 1 ... 64.
Communication Capabiliites Modbus Plus Address Routing Schemes Address Schemes Between Modbus and Modbus Plus 94 Modbus devices use addresses of one byte in the range 1 ... 255. Modbus Plus devices are addressed in the range 1 ... 64, with five consecutive routing bytes contained in each message.
Communication Capabiliites Destination Device Requirements The structure of the Modbus Plus routing address is determined by the type of device at the destination node: l If you are initiating a transaction with another 984 controller, the last (rightmost) nonzero byte in the routing scheme is the destination node address l If you are initiating a transaction with a network adapter in a non-controller nodee.g.
Communication Capabiliites Note: The routing address scheme must be developed as part of an overall network planning process-for details, see the Modbus Plus Network Planning and Installation Guide (840 USE 101 00). The following figure shows an example of a routing address scheme.
Communication Capabiliites Direct, Explicit, and Implicit Attaches Modbus to Modbus Plus Address Conversion The manner in which Modbus Plus converts a Modbus message using bridge mode is determined by the range of the Modbus address (1 ... 255): This shows the address location and the various attach states. 255 Implicit Attach Address 80 79 70 69 65 64 Explicit Attach Address Reserved Direct Attach Address 1 0 Reserved If the address range in the Modbus message is between 1 ...
Communication Capabiliites Note: After the controller’s Modbus Plus node address is entered while in bridge mode, then you will be attached to that controller. If the address range in the Modbus message is between 70 ... 79, the controller initiates an explicit attach address procedure which compares the Modbus address to an address table stored in the controller, immediately following the configured 4xxxx real time clock. Up to 10 addresses in the range 70 ...
Communication Capabiliites Modbus Plus Communication Paths Modbus Plus Message Processing With multiple devices processing messages asynchronously on a Modbus Plus network, an individual device can have several concurrent transactions in process. The A984-145, E984-245/255/265/275/285 Controllers open a communication path when a transaction begins, keep it open during the transaction, and close it when the transaction terminates. After the path is closed, it is available for another transaction.

Hardware Installation 5 At a Glance Introduction The following information describes how to install your Compact hardware.
Hardware Installation Installing DTA Backplanes Procedure for Installing DTA Backplanes These are the DTA installation steps. Step 1 Action Place the top clip on the back of the DTA backplane over the top of the DIN carrier rail and drop the unit into place. Refer to the following graphic. 1 2 2 If the DIN rail is mounted on a wall, the backplane will fall flush against the mounting surface, as shown in (A) below.
Hardware Installation Step Action 3 Push up the securing clips on the bottom of the backplane to clamp the unit onto the DIN rail. Refer to the following graphic. 4 For increased vibration protection in a wall-mount installation, secure the backplane with two mounting screws (4 mm diameter). Use 20 mm long screws with a 7.5 mm DIN rail; use 25 mm long screws with a 15 mm DIN rail. Refer to the following graphic.
Hardware Installation Interlocking Adjacent Backplanes Overview of Interlocking Backplanes The DTA 200 primary backplane must be rack 1 (the leftmost rack) on the DIN rail. One and only one DTA 200 must be used in each Compact Controller installation. Up to three secondary backplanes may be mounted to the right of the DTA 200 primary backplane on a common DIN rail. Interlocking Adjacent Backplanes These are the steps.
Hardware Installation Procedure for Interlocking Adjacent Backplanes Step 4 Action Loosen the screws that secure the ground strap on the secondary backplane and the 0 V system reference connector on the primary backplane: Refer to the following graphic. O V System Reference Connector O V Ground Strap 5 Slide the ground strap left, then secure the ground connection across the backplanes by tightening the two screws: Refer to the following graphic.
Hardware Installation WARNING Connector warning If you use a DTA 202 secondary backplane which does not have a 30pin bus connector on it, it must be the last (rightmost) backplane in the linear drop layout. A DTA 202 cannot be used in a stacked drop layout. Failure to observe this precaution can result in severe injury or equipment damage.
Hardware Installation Installing a BXT 201 Cable in a Stacked Drop Layout Using a BXT201 Cable in a Stacked Drop If you are installing a stacked configuration (two rows of backplanes installed one over the other on two parallel DIN rails), you may connect the last (rightmost) backplane in the top row to the last (rightmost) backplane in the bottom row using a BXT 201 bu The BXT 201 bus extension cable is 500 mm (19.
Hardware Installation Note: The BXT 201 cable connectors are polarized and must be connected properly to the backplanes-the only visible distinction between the two connectors are the labels A and B. The A connector must be attached to the top backplane, and the B connector must be attached to the bottom backplane. Two strain relief cleats are provided with the BXT 201 cable.
Hardware Installation Installing a BXT 203 Cable in a Stacked Drop Layout Overview of the BXT 203 Cable 890 USE 108 00 August 2001 If you are installing a stacked configuration, two rows of backplanes installed one over the other on two parallel DIN rails, you may connect the last (rightmost) backplane in the top row to the first (leftmost) backplane in the bottom row using a BXT 203 bus This cable is 700 mm (27.
Hardware Installation Note: The BXT 203 cable can be installed only one way, because it consists of one 30-pin female connector and one 30-pin male connector. Two strain relief cleats are provided with the BXT 203 cable. They can be attached to the top and bottom DIN rails as shown in the following figure.
Hardware Installation Inserting Modules in the Backplane(s) Module Placement in Backplanes The Compact Controllers and the A120 I/O modules are designed for easy installation. The controller is installed in the first slot in a primary backplane, and I/O modules may be installed in any other slots in a primary or secondary backplane. Attach the module to a hook at the top of the DTA backplane and drop it into the housing.
Hardware Installation If all of the modules are installed in the backplane and the module connections are appropriately wired, place the cover over the assembly. The cover provides a clear pocket over each I/O slot where you can insert the label that comes with each module (as shown in the following figure). The LEDs on the modules remain clearly visible.

Hardware Installation System Power Requirements External Power Supplies The Compact Controllers and some of the A120 I/O modules require an external power source. Power Requirements for a Compact All the Compact Controllers require a 24 Vdc power source to operate. (Detailed information appears in the note in this block.) Modicon offers the optional P120-000, P120-125, P120-250, PRTU-252, and PRTU-258 Power Supplies.
Hardware Installation Power Requirements for the A120 I/O Modules 128 Some A120 I/O modules require a separate external AC or DC power source. If the CPU is powered from its 24 Vdc source, its built-in 5 Vdc power supply provides power across the I/O system bus to all modules in the drop. This table lists the values for both internal and external power draws. A120 I/O Module Internal Power Draw mA @ 5V AS-BADU-204 (+500 mV) <50 AS-BADU-205 (+10 V, +20 mA) <50 AS-BADU-206 (+10 V, +4 ...

Hardware Installation Daisy Chaining Groups of Similar I/O Modules You can daisy chain groups of similar modules within a drop that requires voltages from external power sources. Each group, however, should have dedicated wires to the external power supplies. Typical groups include 24 Vdc input/output modules, 120 Vac input/output modules, 230 Vac modules, or analog modules. The following figure is an example of how a group of relay modules can be daisy chained.
Hardware Installation Distributing Field Power to A120 I/O Field Power Distributed to A120 Modules The following figure is an example of the recommended external 24 Vdc power supply wiring and fusing scheme for discrete, relay, and analog input modules. The 24 Vdc power supply ground is connected to the common functional ground (building ground). A separate circuit is recommended for external loads (outputs), and that circuit should have its ground connected to the common functional ground.
Hardware Installation The following figure is an example of the recommended field wiring and fusing scheme for some ac output modules. Fuses and RC suppression component values must be selected according to load requirements. Loads are shown as boxes. Four of a possible eight loads are shown connected to the DAP 208 module, and all ac input power wiring is shown.
Wiring and Cabling 6 At a Glance Introduction The following information describes the wiring and cabling of your Compact system.
Wiring and Cabling System Bonding and Grounding Overview As part of your installation procedure, provide the Compact system with equipotential bonding of all inactive metal parts, protective grounding, functional grounding, and system reference grounding. Equipotential Bonding A conductive connection, or equipotential bond, must be made between the inactive metal parts of all electronic equipment.
Wiring and Cabling Functional Grounding Functional grounding diverts and neutralizes extraneous electrical signals that interfere with orderly controller logic voltage levels and clock pulses. Extraneous noise can be generated by electrical motors, variable frequency drives, solenoids, etc., and can radiate through the air as well as be conducted through chassis metal and wiring.
Wiring and Cabling System Reference Grounding System Grounding Overview The masked copper grid on the primary DTA 200 housing’s circuit board is the system reference ground. If the DTA 200 housing is mounted on the DIN rail, the functional ground and system reference ground are connected together (only with the Z screw installed with the fiber washer on top and the metal washer on the bottom against the housing). This creates a closed circuit whereby the system reference ground is established.
Wiring and Cabling I/O Module to DIN Rail Grounding Requirements Under certain conditions (painted, coated, or corrosive DIN rails) and with certain I/ O modules, the DIN rail ground may NOT be adequate. The DIN rail resistance should not exceed 0.1 Ohms. To check this specification just measure the voltage drop as described and then calculate the resistance.
Wiring and Cabling Guarding Against EMI/RFI Overview of EMI/ RFI Protection As part of your installation procedure, take care to protect the Compact Controller from extraneous electrical noise interference caused by system wiring. The single best precaution that can be taken against radiated electrical noise is mounting the system inside a metal cabinet that is grounded to the building’s structural metal. Even office environments can benefit from this precaution.
