Possbile incorrect status codes if OptoOPCServer writes to multiple items IDs


Applies To:

OptoOPCServer

Versions Affected:

Problem was discovered in version: R8.1b
Problem is fixed in version: R8.1c

Resolved In Version:

Problem is fixed in version: R8.1c


Symptoms:

The status code returned for an Opto OPC Client may be incorrect if multiple Item Ids are sent to a controller. For example, if an Opto OPC Client such as OptoDataLink is used to send multiple data links to a controller and communication to the controller is interrupted and then resumed, then OptoOPCServer may not report the correct status code to OptoDataLink. The initial problem is reported, but when communication is resumed, OptoOPCServer reports that the problem still exists to OptoDataLink. If communication is again disconnected, OptoDataLink does not detect the new error because OptoOPCServer does not report the original error as being resolved.


Resolution:

Opto 22 has resolved this issue.
