Chapter 2 CompoBus/D Communications Line Design 2-1 Network Configuration Overview The following diagram shows the configuration of a CompoBus/D Network. Terminating Resistors are connected at each end of the trunk line. 24 VDC Trunk line T CompoBus/D cables are used. Trunk line T T T-branch Tap T-branch Tap Drop line Drop line Drop line Trunk line Node Node Power Supply Tap Trunk or T-branch Tap line M Terminating Resistors are connected at each end of the trunk line.
Chapter 2 CompoBus/D Communications Line Design 2-1-2 Connections H Trunk and Drop Lines The trunk line is a cable to which Terminating Resistors are connected at the ends. Drop lines are cables that branch from the trunk lines. A special 5-wire cable is used for both the trunk lines and the drop lines. H Branching Patterns Branching Patterns from Trunk Line 1.One drop line from trunk line 2.Three drop lines (maximum) from trunk line 3.
Chapter 2 CompoBus/D Communications Line Design 2-2 Network Configuration Restrictions CompoBus/D communications are designed to meet a wide range of applications by providing a choice of baud rates and allowing different combinations of T-branch and multi-drop connections. The restrictions of CompoBus/D communications that are required to enable the various communications possibilities are described here.
Chapter 2 CompoBus/D Communications Line Design H Total Drop Line Length The total drop line length is the total sum length of all the drop lines (but not including the trunk line). Do not exceed the maximum total drop line length (even when the length of each individual drop line is 6 m or less). The standard for the total drop line length varies with the baud rate as shown in the previous table.
CompoBus/D Communications Line Design 2-3 Chapter 2 Communications Power Supply 2-3-1 Locating the Communications Power Supply H Basic Concept • The communications power supply must be 24 VDC. • Make sure that the power is supplied from the trunk line. • When providing power to several nodes from one power supply, if possible try to locate the nodes in both directions from the power supply. • Provide power through Power Supply Taps.
Chapter 2 CompoBus/D Communications Line Design H Flowchart Use the flowchart below to determine the communications power supply on the trunk line. Satisfy the conditions for each drop line on page 2-6. Provisionally determine the location of the power supply. Step 1 Determine the best location of the power supply from the graphs. Are the power supply specifications met? Yes No Consider changing the location of the power supply. Consider using Thick Cable.
Chapter 2 CompoBus/D Communications Line Design 1 Locating the Nodes on Both Sides of the Power Supply Power Supply Tap or T-branch Tap Node Node Communications power supply Node Node Node 2 Locating the Nodes on One Side of the Power Supply Note Configuration 1 is recommended for a single power supply to several nodes.
Chapter 2 CompoBus/D Communications Line Design Note 3. Consider changing to Thick Cable to meet specifications if the current capacity of the Thin Cable exceeds 3 A when using Thin Cable for the trunk line. H Setting the Power Supply Location Determine whether or not the current can be supplied normally by finding the current capacity required by each node and the voltage drop in the cables to be used to provide power. Calculate the values below in advance.
Chapter 2 CompoBus/D Communications Line Design H Thick Cable Distance (m) Max. current (A) 0 8.00 25 8.00 50 5.42 100 2.93 150 2.01 200 1.53 250 1.23 300 1.03 350 0.89 400 0.78 450 0.69 500 0.63 8 7 6 Max. current (A) 5 4 3 2 1 0 0 Distance (m) H Thin Cable Distance (m) Max. current (A) 0 3.00 10 3.00 20 3.00 30 2.06 40 1.57 50 1.26 60 1.06 70 0.91 80 0.80 90 0.71 100 0.64 3 2 Max.
Chapter 2 CompoBus/D Communications Line Design 3 Compare the values found in steps 1 and 2, above. If the first value (A) is less than the second (B), this shows that power supply specifications are met and power can be supplied to all nodes at any point in the Network. Note Be sure to refer to the correct graph as the maximum current flow is different for Thick and Thin Cables.
Chapter 2 CompoBus/D Communications Line Design Basically, in the CompoBus/D Network the permissible maximum voltage drop within the system can be specified at 5 V for a power supply line (+V or –V), by calculating the specifications for the voltage of the communications power supply (24 VDC) and the input voltage of the communications power supply of each device (11 to 25 VDC). Of the permissible 5-V maximum voltage drop within the system, the permissible voltage drop is 4.65 V in the trunk lines and 0.
Chapter 2 CompoBus/D Communications Line Design Right Side Calculation Node 4: (40 0.015 + 1 0.005) 0.15 = 0.09075 (V) Node 5: (80 0.015 + 2 0.005) 0.25 = 0.3025 (V) Node 6: (120 0.015 + 3 0.005) 0.15 = 0.27225 (V) If 0.09075 + 0.3025 + 0.27225 = 0.6655 V x 4.65 V, the conditions are satisfied. 2-3-4 Step 3: Splitting the System into Multiple Power Supplies Go to Step 3 if the best location for the nodes cannot be calculated from the formulae.
CompoBus/D Communications Line Design Chapter 2 2-3-5 Dual Power Supplies Because diodes are contained in Power Supply Taps, these taps can be used to construct a dual power supply system in the Network. Dual power supply differs from parallel operation of power supplies, so the following restrictions apply. H Restrictions Dual power supply is basically used to ensure backup power supply, not parallel operation of power supplies.
Chapter 2 CompoBus/D Communications Line Design 2-4 Communications Line Noise Prevention 2-4-1 Communications Line Noise The communications line sends and receives high-speed pulse signals, and checks whether the data is correct by checking the sequence of the signals. If the amount of noise on the communications line is too great, the interference will alter the communications signal data, and communications will be impossible.
Chapter 2 CompoBus/D Communications Line Design Note If the cable grounded to the Inverter is not sufficient and is receiving noise interference, disconnect the grounding cable. Shield 2-4-3 Communications Power Supply Noise Prevention The communications power supply is the most important power supply in a CompoBus/D Network. The following measures will prevent noise in the communications power supply. • Use the recommended power supply (S82H/S82J) for communications.
Chapter 2 CompoBus/D Communications Line Design Suspending the Communications Power Supply S82J power supply DC power supply Insulating material (such as baked board or acrylic board) S82Y-jjN (Mounting Tool) When using S82J power supply When using other power supplies 2-4-4 Noise Prevention Wiring To prevent inductive noise, do not wire the communications line, SYSMAC power lines, and other power lines near to each other.
Chapter 2 CompoBus/D Communications Line Design 2-4-5 Noise Prevention for Peripheral Devices • Install surge suppressors on devices that generate noise, particularly devices that have an inductive component such as motors, transformers, solenoids, and magnetic coils.

Chapter 4 CompoBus/D System Startup 4-1 SYSMAC Word Allocations and Scan List In a CompoBus/D Network, remote I/O and message communications can be used simultaneously. This section describes remote I/O communications, particularly the memory words allocated in the SYSMAC PC that correspond to the remote I/O of the Slaves.
Chapter 4 CompoBus/D System Startup • Slaves that require two words can be allocated two words using only one node address so that the next node addresses can be set for another Slave. • Remote I/O words can be allocated in sequence regardless of the order of the node addresses. Note The Configurator uses one node address. Therefore, the number of Slaves that can be connected is reduced if the Network is to be operated with the Configurator still connected.
Chapter 4 CompoBus/D System Startup • Slave remote I/O allocations providing the number of I/O words allocated to and the node address set for each Slave. • Communications parameters providing the initial remote I/O communications status and the communications cycle time settings. H Scan List Application A scan list is not required for a Network with only one Master Unit and remote I/O that is allocated according to the fixed settings. The scan list is necessary, however, in the following cases.
CompoBus/D System Startup Chapter 4 H Using Scan Lists D Enabling/Disabling a Scan List To enable a scan list, turn ON the Enable Scan List software switch or use the Configurator. To disable a scan list, turn ON the Clear Scan List software switch. Note 1. Scan lists cannot be disabled from the Configurator. The scan list will always be enabled when created on the Configurator and registered in a Master Unit. Note 2. Always enable the scan list during actual system operation.

Chapter 4 CompoBus/D System Startup D Verification Error: Slave I/O Size Differs A verification error (Slave I/O Size Differs) will occur and it will not be possible to start CompoBus/D communications if a Master Unit is being used with the scan list enabled and the type of I/O (input or output) or the number of I/O points registered for a Slave in the scan list does not match the actual I/O specifications of the Slave that is connected to the Master Unit.
CompoBus/D System Startup Chapter 4 2. Set the initial settings for the Slaves: Node address (DIP switch) Baud rate (DIP switch) Etc. 3. Mount the Master Unit and wire the Network. For CV-series PCs, Master Units are treated as CPU Bus Units and can be mounted to the CPU Rack or Expansion CPU Rack. Only one Master Unit can be mounted if a Configurator is not used, but up to 16 Master Units can be mounted if a Configurator is used.
Chapter 4 CompoBus/D System Startup 4-1-4 Free Allocations H Allocation Areas and Maximum Words for Different PCs When free allocations are used, the remote I/O areas consist of input blocks 1 and 2, which input Slave data to the PC, and output blocks 1 and 2, which output data from the PC to the Slaves. These four blocks can be allocated as desired using the following words. Each block, however, must consist of continuous words within one data area.
Chapter 4 CompoBus/D System Startup H Free Allocation Restrictions • Each node address can be set only once in the output blocks and once in the input blocks. The same node address cannot be set twice. WRONG Output block 1 Output block 2 Node 02 Node 02 • If a Configurator is used to freely allocate words or bytes to each Slave, only a Slave using only one byte (8 bits) can be set in the leftmost byte of the allocated word.

Chapter 5 CompoBus/D Communications Card Operations 5-2 Message Communications (DeviceNet Explicit Messages) There are two types of CompoBus/D communications: Remote I/O and message communications. This sections explains CompoBus/D Communications Card message communications. With message communications, specific instructions (SEND, RECV, CMND, and IOWR) are used for reading and writing data between Master and Slave Units.
Chapter 5 CompoBus/D Communications Card Operations Note Message communications are supported by CV-series and C200HX/HG/HE PCs, but not by C200HS PCs. H Overview of Explicit Messages Explicit messages are sent and received as described below. Basically explicit message communications are executed in 1-byte (8-bit) units.
Chapter 5 CompoBus/D Communications Card Operations D C: Control Code The control code is set as shown below for CompoBus/D Master Units. C: Destination unit address: FE (Master Unit) Master Unit must be set for explicit messages. Destination node address: 0 to 3F hex (0 to 63) The Master Unit node address must be set for explicit messages. Response setting: ON: No response. OFF: Response required. Must be OFF (response required) for explicit messages.
Chapter 5 CompoBus/D Communications Card Operations H Message Timing The Message Communications Enabled Flag must be used as an execution condition for the Master when IOWR is used. Be sure this flag is ON before executing IOWR. If IOWR is executed when this flag is OFF, a Special I/O Unit error may be generated for the Master. Execution condition Message Communications Enabled Flag A (@) IOWR C S B D B 25506 Equals Flag A 1.
Chapter 5 CompoBus/D Communications Card Operations H Timing of Message Response Reading Responses are read when the Message Communications Enabled Flag turns ON in the next cycle. The Message Communications Enabled Flag will turn OFF when a Master Unit is executing message communications. If the message response is faster than the PC ladder program cycle time, the Message Communications Enabled Flag will remain ON and response processing will not be possible.
CompoBus/D Communications Card Operations Chapter 5 5-2-3 SYSMAC CV-series Message Transmission H Using CMND(194) With CV-series PCs, CMND(194) is used to send explicit messages. To send an explicit message, it is necessary to place FINS command “2801” in front and to send the command to the Master Unit. The Master Unit that receives the command converts the command data to an explicit message and transfers it to the destination node.

Chapter 5 CompoBus/D Communications Card Operations 5-2-7 AC/DC Drive Objects: Class 2A Hex AC/DC drive objects are assigned to command-related functions for drive devices such as Inverters and Servomotors. Command-related data reading and writing, monitor data reading, set data scale changes, and so on, are all enabled. These functions are shared with similar functions used for remote I/O, so even if they have been set for message operations they may get rewritten for remote I/O.

Chapter 5 CompoBus/D Communications Card Operations 5-3 Switching Remote I/O Operation To use remote I/O operations other than the standard remote I/O operation it is necessary to switch the remote I/O operation. There are two ways to switch: • Use the Configurator to set the remote I/O instance IDs for parameter objects. • Set the remote I/O instance IDs for connection objects.
Chapter 5 CompoBus/D Communications Card Operations 5. Set up the Master Unit and 3G3FV Inverter connection by turning ON their power. The remote I/O connection will then start up with the specified remote I/O operation. When creating scan lists, set the scan list to disable mode once and then create scan lists or change the settings as follows for the Inverter I/O allocation byte number from the Configurator.

Chapter 5 CompoBus/D Communications Card Operations 5-4 Special Remote I/O Operation There are three kinds of CompoBus/D remote I/O operation: Basic remote I/O, standard remote I/O (the default setting), and special remote I/O. This section explains special remote I/O. Special remote I/O operation enables using all the functions of 3G3FV-series Inverters, and setting and reading all parameters. These operations have been developed independently, and are not part of the DeviceNet standard.
Chapter 5 CompoBus/D Communications Card Operations H Setting Data for Operations and Parameter Constants Read data and write data to be set for operations and parameters are calculated as shown below and then transmitted in hexadecimal. • Convert to hexadecimal values with the operation/parameter minimum setting value as 1. • Negative numbers are expressed as two’s complements. • If the original data is already displayed in hexadecimal, it is transmitted as is.
CompoBus/D Communications Card Operations Chapter 5 Note 1. Unless an enter command is transmitted, data will not be enabled and the Inverter may not start. Note 2. The enter command requires a parameter constant (Register No. 0100 or higher). Since the run command or frequency reference (Register No. 0000 to 000F) is stored only in the RAM area, set data will be enabled without an enter command.
