Resolved In Version:

Symptoms:

Under rare circumstances, the SNAP-PAC controllers could exhibit unexpected behavior, including a reset or analog point values not updating. These unexpected behaviors are most likely to occur on controllers with heavy Ethernet traffic.


Resolution:

Opto 22 has corrected this issue. The correction is related to enforcing thread-safeness, when one chart or another thread, is not accessing resources at the same time as another.
