Versions Affected:

All PAC Firmware versions through R10.0d

Resolved In Version:

PAC firmware R10.0f

Symptoms:

The controller may stop responding after you stop the strategy. This might happen if a chart in the strategy has locked an object (with the Flag Lock command) and did not unlock it (with the Flag Unlock command) before the strategy was stopped.

Workaround:

You can minimize the possibility of this happening by modifying strategy logic: when using the Flag Lock command, minimize the amount of time the object is locked (using the Flag Unlock command).

Resolution:

Opto 22 has resolved this issue.
