Hi everybody, following the tip of Ken Roach, i'm opening a new thread to my problem.
I have a redundant PLC system, each chassis have two 1756-EBNT card. One of them got bad and we replaced. But the new one had no IP configured.
So, we try to put the same IP of his pair using the BOOTP server (the one we are configuring the IP is now as slave). When we put back the ethernet cable in the card, both cards displays the error "duplicate IP". If we put the IP of the slave already as the IP of the master + 1, everything works fine, but when we do a switch-over (put the slave as the master), they don't switch the IP address (the other ethernet card pair switch the IP).
The other problem is that if we try to go to RSLinx and select the 'Static' option, when we click in 'apply' we get the following error: "An unexpected communications error has occurred. General status is 0x0009".
We also right-click on the SRM module and click in the "Module Configuration", but nothing appears.
We try connecting directly to the ebnt card using a ethernet cable. And also try connecting to the processor using the RS-232 port and the driver RS-232 DF1 drivers, but experienced the same results.
We are using the 15.02 revision of the ControlLogix redundancy. The firmware of the controller is 15.57.
The firmware of the cards is 4.3.2. I just checked the manuals and they are supported. But they have to be, because the other pair has the same firmware version, and the redundancy is working fine.
The firmware of the pair is the same (when they are powered-up, they show the value 4.3.2, is there the most secure way to know the firmware?).
We are using the RSLinx Lite and have no RSLogix installed on the machines. This could be why we don't being able to see the SRM module configuration?
Anyone has an idea of the problem?
Thanks very much
