PLC AC500 controller PM573 ETH suddenly goes stop mode
We have PLC AC500 with PM573 ETH controller and CM572 communication module for grab EOT crane operation. For the same we have 2 nos ACS 880 drive as Master follower. Our PLC goes stop suddenly that time we found in Automation builder 2.1 profibus device no communication failure and in drive FPBA module network led blink red and module led blinking green. I.e. communication lost. We had already change all hardware related to this. But till now problem comes, after power recycling it solve automatically.
It happens after Communication firmware upgrades.
Please response on urgent, our production already hampering for this issue.
Now this problem comes irregularly many times.
From the description, it looks like a HW problem: did you also carefully check the connection cables and connectors?
Sometimes a false contact in the connector connections can cause the failure you have described.
As for the updates of the FW, it seems unlikely that the cause is of this kind, however you can take note to Automation Builder of the versions of the respective modules, that is first of all the CPU, then the CM572 and then the FPBA modules on board the drives.
