We have a system that connects to various models of Allen Bradley PLC's ControlLogix, MicroLogix, SLC 5/05's. The system was commissioned and working fine.
I sent the plant this notice: ICSA-13-095-02A: Rockwell Automation FactoryTalk and RSLinx Multiple Vulnerabilities
The AB rep provided an update for the wrong version of RSLinx and everything in RSLinx lost communication. I wasn't involved up until this point so I am uncertain of the specific RSLinx Classic version, but this is where the issues start.
The majority of the plcs and the PC running RSLinx are on a network range of xxx.yyy.128.zzz One specific plc is on the network xxx.yyy.126.101. (This is a 5/05 PLC)
We have an old box running Windows XP with RSLinx 2.42 All communications work fine right now. (There are approximately a dozen communicating PLC's on the xxx.yyy.128.zzz and xxx.yyy.126.101 is communicating.)
We completely removed RSLinx from the Windows 7 box. We installed RSLinx 2.57 and configured the drivers. All devices that we configured in the xxx.yyy.128.zzz are communicating, the only one that does not is the xxx.yyy.126.101.
I actually pull the network cable out of the XP box and plug in the 7 box. All network adapter settings are the same between XP and 7. All driver settings in RSLinx are the same between XP and 7. Windows firewall is turned off. I can tracert to all plcs successfully. (It is the same route as when I tracert on XP.) I have deleted the Harmony files.
I actually did a system restore on the Windows 7 box prior to the vendor being on-site and I still have the same issue. (All PLC's communicate except xxx.yyy.126.101.)
If I pull the network cable out of the 7 box and connect the XP box RSLinx on the XP can connect to all PLCs.
There are no firewalls between the PC and PLC. Any ideas of what to check next?
