Client Connection Lost to Server
We have a Compact HMI 800 SCADA in our site which is fully working.
My office mate disconnected the ethernet cable temporarily on the client computer. After a few minutes, he return the cable back to client computer, however after that, the workplace no longer connecting to server computer.
We ping both AC800M plc and SCADA server and they were both existing in the client network, so which means we are physically connected to the remote station.
We already restart our computer several times but still we are unable to communicate with the Server. The CHMI_Server(on the notification icon) is disabled and does not turn green even after waiting for serveral minutes.
We are monitoring from time to time the status of substation meters. I am hoping for your immediate response regarding on how we can solve the issue.
Thank you in advance.
For urgent matters, do please involve your regional ABB support center (AKS is not a substitute to regular support via regional ABB).
I assume the CHMI server is OK and workplaces started there still show PLC information; and the problem is contentrated to the CHMI client only?
Starting with version 5.1, 800xA (incl. CHMI) require RNRP connection before any workplace can be started.
-> Does your CHMI client's RNRP Monitor show the CHMI server?
-> Does the [Workplace Structure]Web System Workplace:System Event List contain any error messages, e.g. when the CHMI client is restarted or workplace launch is attempted?
Please revert with full detail.
