Resolved In Version:
For groov EPICs: 3.5.1
For SNAP PACs: R10.4e
After the following events, the I/O unit should report that communication is disabled:
- An I/O unit cycles power.
- The PAC Control strategy tests if the I/O unit is available with the following combination of commands:
Is I/O Unit Ready?
I/O Unit Communication Enabled?
With this issue, if no other commands are run before that combination of commands, the I/O unit may incorrectly report communication as enabled.
Opto 22 has resolved this issue.
