Chapter 2 Installing Your Controller This chapter shows you how to install your controller. The only tools you require are a flat or Phillips head screwdriver and drill.
20 Installing Your Controller EMC Directive This product is tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) and the following standards, in whole or in part, documented in a technical construction file: • EN 61000-6-4 EMC - Part 6-4: Generic Standards - Emission Standard for Industrial Environments • EN 61000-6-2 EMC - Part 6-2: Generic Standards - Immunity for Industrial Environments This product is intended for use in an industrial environment.
Installing Your Controller ATTENTION ATTENTION ATTENTION Safety Considerations 21 Electrostatic discharge can damage semiconductor devices inside the controller. Do not touch the connector pins or other sensitive areas. Vertical mounting of the controller is not supported due to heat build-up considerations. Be careful of metal chips when drilling mounting holes for your controller or other equipment within the enclosure or panel.
22 Installing Your Controller Use only the following communication cables in Class I, Division 2 hazardous locations.
Installing Your Controller 23 Power Distribution There are some points about power distribution that you should know: • The master control relay must be able to inhibit all machine motion by removing power to the machine I/O devices when the relay is de-energized. It is recommended that the controller remain powered even when the master control relay is de-energized. • If you are using a DC power supply, interrupt the load side rather than the AC line power.
24 Installing Your Controller Power Considerations The following explains power considerations for the micro controllers. Isolation Transformers You may want to use an isolation transformer in the AC line to the controller. This type of transformer provides isolation from your power distribution system to reduce the electrical noise that enters the controller and is often used as a step-down transformer to reduce line voltage.
Installing Your Controller 25 This is referred to as a power supply shutdown. The processor then performs an orderly shutdown of the controller. Input States on Power Down The power supply hold-up time as described above is generally longer than the turn-on and turn-off times of the inputs. Because of this, the input state change from “On” to “Off ” that occurs when power is removed may be recorded by the processor before the power supply shuts down the system. Understanding this concept is important.
26 Installing Your Controller Master Control Relay A hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens, the master control relay is de-energized.
Installing Your Controller TIP 27 Do not control the master control relay with the controller. Provide the operator with the safety of a direct connection between an emergency-stop switch and the master control relay. Using Emergency-Stop Switches When using emergency-stop switches, adhere to the following points: • Do not program emergency-stop switches in the controller program. Any emergency-stop switch should turn off all machine power by turning off the master control relay.

42 Wiring Your Controller Do not run signal or communications wiring and power wiring in the same conduit. Wires with different signal characteristics should be routed by separate paths. TIP • Separate wiring by signal type. Bundle wiring with similar electrical characteristics together. • Separate input wiring from output wiring. • Label wiring to all devices in the system. Use tape, shrink-tubing, or other dependable means for labeling purposes.
Wiring Your Controller 43 Screw-cage clamp terminal block Using Surge Suppressors Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type of surge suppression to protect and extend the operating life of the controllers output contacts is required. Switching inductive loads without surge suppression can significantly reduce the life expectancy of relay contacts.
44 Wiring Your Controller suppressor can also be used. See for recommended suppressors. As shown below, these surge suppression circuits connect directly across the load device. +24V DC VAC/DC Out 0 Out 1 Out 2 Out 3 Relay or Solid State DC Outputs Out 4 Out 5 Out 6 Out 7 24V DC common COM IN4004 Diode (A surge suppressor can also be used.)

Wiring Your Controller Controller I/O Wiring 53 Minimizing Electrical Noise Because of the variety of applications and environments where controllers are installed and operating, it is impossible to ensure that all environmental noise will be removed by input filters. To help reduce the effects of environmental noise, install the MicroLogix 1100 system in a properly rated (for example, NEMA) enclosure. Make sure that the MicroLogix 1100 system is properly grounded.
54 Wiring Your Controller • The controller does not provide loop power for analog inputs. Use a power supply that matches the transmitter specifications as shown below.
Wiring Your Controller 55 Grounding Your Analog Cable Use shielded communication cable (Belden #8761). The Belden cable has two signal wires (black and clear), one drain wire, and a foil shield. The drain wire and foil shield must be grounded at one end of the cable.

Chapter 7 Online Editing The online editing function lets you monitor and modify your ladder program when your programming terminal is connected to a MicroLogix 1100 processor. Overview of Online Editing Online editing of ladder programs is available when using MicroLogix 1100 processors. Use this function to make changes to a pre-existing ladder program. Online editing functions consist of inserting, replacing, and deleting rungs in an existing ladder program while online with the processor.
148 Online Editing The following table summarizes the differences between offline and online editing. Offline Online Data table file resizing is not permitted. No restrictions exist. Full editing capabilities are allowed. Program file creation and deletion are not permitted. Alteration of file protection is not permitted. Alteration of static and constant data file values is not permitted. Indexing across file boundary selections is not permitted. Force protection selection is not permitted.
Online Editing 149 • modify rung — when an existing rung is modified two edit zones are created. The original rung is indicated by replace zone markers on the power rail. A copy of the original rung is made so you can insert, delete, or modify instructions. This rung is indicated by insert zone markers on the power rail. Thus, an IR pair is created when you modify a rung. • runtime online editing — the user program is executing when an edit takes place.
150 Online Editing Data Table File Size Online editing cannot change the size of existing data tables nor can new ones be created. However, some ladder instructions, when programmed cause data table values to change. These instructions are those that require timer, counter, and control addresses to be specified. Online Edit Error If either electrical interference, communication loss, or a power cycle occur during online edit session, program integrity may be impacted.
Online Editing 151 Interval be increased from the default of 1.25 seconds to 8 seconds as shown in the following figure. A Download Before Starting Online Edit At least one download is required before starting online edit. If you are using a MicroLogix 1100 from out-of-box state or after clear processor memory or firmware upgrade, at least one download is required before starting online edits.
152 Online Editing This problem happens only in out-of-box state or after clear processor memory. ATTENTION PTO and PWM instructions may not be deleted during runtime online edit. This is because if the PTO or PWM instructions were deleted during runtime online edit, outputs could stop in an unpredictable state, causing unexpected equipment operation.
Online Editing ATTENTION ATTENTION Types of Online Editing 153 When editing a rung that contains an MCR instruction, both the MCR start and MCR end rungs must be edited (whether it be test/assemble/cancel) at the same time. We recommend that you fully understand the possible results of the edit to the system under control. Failure to properly edit a running program could result in unexpected controller operation. Physical injury or equipment damage may result.
154 Online Editing IMPORTANT Online editing is not available when the mode switch in LCD screen is in the RUN position. ATTENTION Use the online editing function while in the RUN mode to make minor changes to the ladder program. We recommend developing your program offline since ladder rung logic changes take effect immediately after testing your edits. Improper machine operation may occur, causing personnel injury or equipment damage.

Appendix E Connecting to Networks via RS-232/RS-485 Interface The following protocols are supported from the RS-232/485 communication channel (Channel 0): • • • • • • RS-232 Communication Interface DF1 Full Duplex DF1 half-duplex Master/Slave DF1 Radio Modem DH-485 Modbus RTU Master/Slave ASCII The communications port on the MicroLogix 1100 utilizes a combined RS-232/485 interface.
200 Connecting to Networks via RS-232/RS-485 Interface The MicroLogix™ controller supports the DF1 Full-Duplex protocol via RS-232 connection to external devices, such as computers, or other controllers that support DF1 Full-Duplex. DF1 is an open protocol. Refer to DF1 Protocol and Command Set Reference Manual, publication 1770-6.5.16, for more information. DF1 Full-Duplex protocol (also referred to as DF1 point-to-point protocol) is useful where RS-232 point-to-point communication is required.
Connecting to Networks via RS-232/RS-485 Interface DF1 Half-Duplex Protocol 201 DF1 Half-Duplex protocol is a multi-drop single master/multiple slave network. DF1 Half-Duplex protocol supports data transparency (American National Standards Institute ANSI - X3.28-1976 specification subcategory D1). In contrast to DF1 Full-Duplex, communication takes place in one direction at a time.
202 Connecting to Networks via RS-232/RS-485 Interface Example DF1 Half-Duplex Connections Rockwell Software RSLinx 2.0 (or later), SLC 5/03, SLC 5/04, and SLC 5/05, PLC-5, MicroLogix 1100, or MicroLogix 1200 and 1500 processors configured for DF1 Half-Duplex Master.
Connecting to Networks via RS-232/RS-485 Interface 203 Using Modems with MicroLogix™ Programmable Controllers The types of modems you can use with MicroLogix™ controllers include the following: • dial-up phone modems. A MicroLogix™ controller, on the receiving end of the dial-up connection, can be configured for DF1 Full-Duplex protocol with or without handshaking. The modem connected to the MicroLogix controller should support auto-answer. The MicroLogix 1100 supports ASCII out communications.
204 Connecting to Networks via RS-232/RS-485 Interface For general multi-drop modem connections, or for point-to-point modem connections that require RTS/CTS handshaking, use DF1 Half-Duplex slave protocol. In this case, one (and only one) of the other devices must be configured for DF1 Half-Duplex master protocol. IMPORTANT TIP Publication 1763-UM001D-EN-P - March 2011 Never attempt to use DH-485 protocol through modems under any circumstance.
Connecting to Networks via RS-232/RS-485 Interface DH-485 Communication Protocol 205 The DH-485 protocol defines the communication between multiple devices that coexist on a single pair of wires. DH-485 protocol uses RS-485 Half-Duplex as its physical interface. (RS-485 is a definition of electrical characteristics; it is not a protocol.) RS-485 uses devices that are capable of co-existing on a common data circuit, thus allowing data to be easily shared between devices.
206 Connecting to Networks via RS-232/RS-485 Interface Devices that use the DH-485 Network In addition to the MicroLogix™ controllers, the devices shown in the following table also support the DH-485 network. Allen-Bradley Devices that Support DH-485 Communication Catalog Number Bulletin 1761 Controllers Bulletin 1762 Description Installation Function Publication MicroLogix 1000 These controllers support DH-485 communications. 1761-6.3 These controllers support DH-485 communications.
Connecting to Networks via RS-232/RS-485 Interface 207 • type of process being controlled. • network configuration. The major hardware and software issues you need to resolve before installing a network are discussed in the following sections. Hardware Considerations You need to decide the length of the communication cable, where you route it, and how to protect it from the environment where it will be installed.
208 Connecting to Networks via RS-232/RS-485 Interface Running the communication cable through conduit provides extra protection from physical damage and electrical interference. If you route the cable through conduit, follow these additional recommendations: – Use ferromagnetic conduit near critical sources of electrical interference.

216 Connecting to Networks via Ethernet Interface MicroLogix 1100 and PC Connections to the Ethernet Network The MicroLogix 1100 Ethernet connector conforms to ISO/IEC 8802-3 STD 802.3 and utilizes 10/100Base-T media. Connections are made directly from the MicroLogix 1100 to an Ethernet hub or switch. The network setup is simple and cost effective. Typical network topology is pictured below.
Connecting to Networks via Ethernet Interface IMPORTANT 217 When connecting the MicroLogix 1100 Ethernet port to a 10/100Base-T Ethernet switch, note the following recommendations: • Use the auto negotiation function for both the switch port and the MicroLogix 1100 Ethernet port • If you want to force to a specific speed/duplex mode, you should force the MicroLogix 1100 Ethernet port and leave the switch in auto negotiation mode to match speed/duplex settings of the MicroLogix 1100. Ethernet port.
218 Connecting to Networks via Ethernet Interface The standard Ethernet cable is terminated in accordance with EIA/TIA 568B on both ends. The crossover cable is terminated to EIA/TIA 568B at one end and EIA/TIA 568A at the other, exactly as shown in the two color coded plugs below. The following figures show how the TIA/EIA 568A and 568B are to be terminated. There are four pairs of wires contained in a CAT5 UTP cable.
Connecting to Networks via Ethernet Interface TIP 219 The most common wiring for RJ45 cables is the "straight through" cable which means that pin 1 of the plug on one end is connected to pin 1 of the plug on the other end. The straight through RJ45 cable is commonly used to connect network cards with hubs on 10Base-T and 100Base-Tx networks. On network cards, pair 1-2 is the transmitter, and pair 3-6 is the receiver. The other two pairs are not used.
220 Connecting to Networks via Ethernet Interface In order to receive messages from another device on Ethernet, an “incoming” connection must be established. This incoming connection is made by the sending processor and uses one incoming connection in the receiving processor. The MicroLogix 1100 supports a maximum of 32 connections, allowing a maximum of 16 outgoing and a maximum of 16 incoming simultaneous connections with up to 32 other devices or applications.
Connecting to Networks via Ethernet Interface 221 The MicroLogix 1100 will check every 2 minutes for a duplicate IP address on the network. Configuring the Ethernet Channel on the MicroLogix 1100 There are two ways to configure the MicroLogix 1100 Ethernet channel 1.
222 Connecting to Networks via Ethernet Interface Parameter Description Default Status SMTP Client Enable (Series B only) The SMTP Client service enable switch. When SMTP is enabled, MicroLogix 1100 is capable of transmitting e-mail messages generated by a 485CIF write message with a string element. There must be a SMTP server on the network capable of processing e-mail service. This provides an extremely versatile mechanism to report alarms, status, and other data-related functions.
Connecting to Networks via Ethernet Interface 223 The host system’s BOOTP configuration file must be updated to service requests from MicroLogix 1100 controllers. The following parameters must be configured: Parameter Description IP Address A unique IP Address for the MicroLogix 1100 controller. Subnet Mask Specifies the net and local subnet mask as per the standard on subnetting RFC 950, Internet Standard Subnetting Procedure.
224 Connecting to Networks via Ethernet Interface Using the Rockwell BOOTP/DHCP Utility The Rockwell BOOTP/DHCP server utility is a standalone program that incorporates the functionality of standard BOOTP software with a user-friendly graphical interface. It is located in the Utils directory on the RSLogix 500 installation CD. The newest version of the utility can be downloaded from www.ab.com/networks/bootp/index.html.
Connecting to Networks via Ethernet Interface 225 2. In the Request History panel you will see the hardware addresses of devices issuing BOOTP or DHCP requests. 3. Double-click on the hardware address of the device you want to configure. You will see the New Entry pop-up window with the device's Ethernet Address (MAC). 4. Enter the IP Address and Description you want to assign to the device, and click OK. Leave Hostname blank.
226 Connecting to Networks via Ethernet Interface The device will be added to the Relation List, displaying the Ethernet Address (MAC) and corresponding IP Address, Subnet Mask, and Gateway (if applicable). Using a DHCP Server To Configure Your Processor A DHCP server automatically assigns IP addresses to client stations logging onto a TCP/IP network. DHCP is based on BOOTP and maintains some backward compatibility.
Connecting to Networks via Ethernet Interface 227 If your network is divided into subnetworks that use gateways or routers, you must indicate the following information when configuring channel 1: • subnet mask • gateway address A subnet mask is a filter that a node applies to IP addresses to determine if an address is on the local subnet or on another subnet. If an address is located on another subnetwork, messages are routed through a local gateway to be transferred to the destination subnetwork.
228 Connecting to Networks via Ethernet Interface Manually Configuring Channel 1 for Controllers on Subnets If you are manually configuring channel 1 for a MicroLogix 1100 controller located on a subnet, deselect both of the “BOOTP Enable” and “DHCP Enable” options by clicking on the checked box, as shown in the figure below. See the table below to configure the subnet mask and gateway address fields for each controller via your programming software.
