ControlLogix Ethernet Communication Interface Module 7 For information about installing these products, refer to the publications listed in this table. Chassis Type Series B: 1756-A4, -A7, -A10, -A13, -A17 Chassis Installation Power Supply Power Supply Installation Pub. No. 1756-IN080 1756-PA72/B Pub. No. 1756-5.67 1756-PB72/B 1756-PA75/A 1756-PB75/A Pub. No. 1756-5.78 Determining Module Slot Location You can install the module in any slot in the ControlLogix chassis.
ControlLogix Ethernet Communication Interface Module Installing the Module in the Chassis 1 Align the circuit board with top and bottom guides in the chassis. Circuit Board 2 Slide the module into the chassis. Make sure the module backplane connector properly connects to the chassis backplane. 3 The module is properly installed when it is flush with the power supply or other installed modules.
ControlLogix Ethernet Communication Interface Module 9 Removing or Replacing the Module (when applicable) 1 Push on upper and lower module tabs to disengage them. 2 Slide module out of chassis. IMPORTANT If you are replacing 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.
ControlLogix Ethernet Communication Interface Module Installing or Removing the Module While Power Is Applied You can install or remove the module while chassis power is applied. Please observe the following precautions. WARNING ! When you insert or remove the module while backplane power is on, or you connect or disconnect the communications connectors, an electrical arc can occur. This could cause an explosion in hazardous location installations.
ControlLogix Ethernet Communication Interface Module 11 Connecting the Module to the Ethernet Network If you connect or disconnect the Ethernet 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. Be sure that power is removed or the area is nonhazardous before proceeding.
ControlLogix Ethernet Communication Interface Module IMPORTANT Connecting the module to the network via an Ethernet switch will reduce collisions and lost packets and increase network bandwidth. See the EtherNet/IP Performance and Application Guide, publication ENET-AP001, for more information.
ControlLogix Ethernet Communication Interface Module 13 Checking Power Supply and Module Status Check the LED indicators to determine if the power supply and module are operating properly. ETHERNET POWER RXD TXD OK OK indicator is RED, then FLASHING RED (or is GREEN if module is configured). Power Supply indicator is GREEN If the Power Supply and OK indicators are not in the states described above refer to the following troubleshooting section.
ControlLogix Ethernet Communication Interface Module Troubleshooting the Module This table describes module health (OK) indicator displays, module status, and recommended action: If the OK indicator is then module status is take this action Off Not operating. Apply chassis power. Verify module is completely inserted into chassis and backplane. Red, then flashing red or flashing green Performing powerup diagnostics. None, normal operation. Green Operating. None. Red flashing Not configured.
