To install these products, refer to these publications. Chassis Type Chassis Installation Instructions Power Supply Power Supply Installation Instructions 1756-A4/B 1756-A7/B 1756-A10/B 1756-A13/B Publication 1756-IN080 1756-PA72/C, 1756-PB72/B, 1756-PA75/B, 1756-PB75/B Publication 1756-IN613 Determine Module Slot Location Install the module in any slot in the ControlLogix chassis. You can install multiple 1756-EN2TR or 1756-EN3TR modules in the same chassis.
Use the Rotary Switches Item 2 1 Description 1 Front of module 2 Top of module 3 Rotary switches 31587 3 The module reads the rotary switches first to determine if they are set to a valid number for the last portion of the IP address. Valid numbers range from 001…254. When the switches are set to a valid number, the module’s IP address is 192.168.1.xxx (where xxx represents the number set on the switches). The module’s subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.
Use a DHCP/BOOTP Server If you do not have a large computer that can act as a boot server, download our DHCP/BOOTP software so you can use a personal computer as a DHCP/BOOTP server. To set the network address by using the Rockwell Automation DHCP/BOOTP server, follow these steps. 1. Access the DHCP/BOOTP utility at http://www.ab.com/networks/ethernet/bootp.html. 2. Download the version 2.3.2 DHCP/BOOTP utility. 3. Extract the zipped files to a temporary directory. 4.
Use RSLinx Classic or RSLogix 5000 Software Follow the procedures outlined in the online help that accompanies this software to set the network address. Install the Module To install the module, follow this procedure. WARNING When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
2. Slide the module into the chassis, making sure the module backplane connector properly connects to the chassis backplane and noting that the module is properly installed when it is flush with the power supply or other installed modules. 31589-M Wire the Ethernet Connector Use an RJ45 connector to connect to the EtherNet/IP network. Wire the connector as shown.
Grounding Considerations The grounding and bonding must be of equal potential between all devices in the communication coverage area. Connect the Module to the EtherNet/IP Network Follow this procedure to connect the module to the network. WARNING If you connect or disconnect the communication cable with power applied to this module or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations.
Download the 1756-EN2TR Module Add-on Profile (AOP) [RSLogix 5000 Software Version 17.01 Only] If you are using RSLogix 5000 software, version 17.01, you need to download the AOP. Follow these steps to download the AOP. IMPORTANT The 1756-EN3TR module requires RSLogix 5000 software version 18. 1. Locate the module AOP on http://www.rockwellautomation.com/support/controlflash/LogixProfiler.as. IMPORTANT You need a Rockwell Automation MySupport account to download the AOP.
Use the Module in a Device-level Ring (DLR) Network The module is configured by default to be used in a linear or star topology, or as a ring node in a DLR network. Follow these steps to use the module in a DLR network as a ring supervisor. 1. If you are using the unit as a ring supervisor, follow the procedures outlined in the online help that accompanies RSLinx or RSLogix 5000 software to enable the ring supervisor function with this software.
Use a USB cable to connect your computer to the USB port. The connection lets you download programs to controllers and configure Ethernet modules directly from your computer. ATTENTION The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain hubs. Apply Chassis Power and Check Status Indicators To complete this procedure, follow these steps. 1. Apply chassis power as shown in the figure. 2.
The display then alternates between OK and port link status for both ports. TM 10/100 BASE T LNK1 LNK2 OK LNK1 LNK2 OK Install or Remove the Module Under Power You can install or remove this module while chassis power is applied. WARNING When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
To remove or replace the module, use this procedure. 1. Push on the upper and lower module tabs to disengage them. 31590-M 2. Slide the module out of chassis. 31591-M IMPORTANT If you want to replace an existing module with an identical one, and you want to resume identical system operation, you must install the new module in the same slot.
Status Indicators If the alphanumeric display and status indicators do not sequence through the expected states, refer to the following troubleshooting tables. The three bi-color (red/green) status indicators on the module provide diagnostic information about the module and its connections to the network. Indicator Status Description LNK1, LNK2 Off No link, or port administratively disabled, or port disabled due to rapid ring faults or partial network fault on active ring supervisor (LNK2).
Indicator Status Description OK Off Module does not have 24V DC power. Verify that there is chassis power and the module is completely inserted into chassis and backplane. Flashing green Module is not configured. Green Module is operating correctly. Flashing red Module detected a recoverable fault. A configuration error may have caused the fault. Red Recycle power to the module. If this does not clear the fault, replace the module.
