LVEA/PSL dust monitor EPICS IOC restarted in attempt to clear PSL-102 dust monitor not updating
PSL dust 102 has not been updating for some time, while PSL dust 101 is working fine. As a first try to fix the problem, I stopped the EPICS IOC code and restarted it. This did not fix the problem.
Before and after the restart, the IOC was reporting communication issues with PSL Dust-102
