I have redundant Ignition 7.7.8 on 2 server with Java 8.11 on Windows 7 64, and SIMATIC NET OPC.
On one of 4 clients occurred error when operator tried to new value by button with direct link: “Error writing to tag … Write timed out [C]”, at the same time on the server the following log is generated:
11:50:32 COMSubscription Received transaction completion event for unknown item, client id: 0
11:51:01 Provider[Common] [[Common]...] Error writing to OPC address ... Result code: [TIMEOUT] nullBut value on PLC changed after that. At the same time other records are not made.
It seems that the Ignition is sometimes incorrectly interprets the response, and at the same time with this recording of other records is not performed.
How can I solve the problem or at least to hide errors?
