Allen-Bradley PLC-2 via TCP/IP - Hardware Setup

Because this driver does not receive information regarding the state of the physical transport layer, no specific details can be given for setting up communications. Follow these general steps:

1. Set up the PLC 5/250 resource manager or AB-KA module. Assign the IP address, and test that it is valid by using the Ping program.

2. Set up the PLC-2 and 1771-KA/KA2 for communications on the DH network to which it is connected. Be sure to set the Node Address, Baud Rate, and Write Options on each PLC communication module.

3. Check that you can communicate to the PLC using offlink addressing. You can use the utility accompanying the Allen-Bradley Interchange software to verify that you can communicate from a PC over Ethernet.

Plant SCADA Computer Setup

Setup your specific Ethernet card as required and confirm basic network communications before proceeding with the communications configuration for the ABTCP driver. Refer to the documentation accompanying your hardware for instruction. You must also setup TCP/IP protocol on your Plant SCADA computer.
