Aaron S., Richard M., Patrick T. I rescanned PLC1, PLC2 and PLC3 in the h1ecatx1 system manager. I then moved the link under 'End Link L0:End Link L3_4:ALS Laser Table Relay:Channel 2:Output' from 'PLC2:Standard:Outputs:AlsEndLaserHeadOut:NoiseEaterRelayOff' to 'PLC1:Standard:Outputs:IlluminatorOut:IlluminatorRelayOn'. I committed the change to svn. Richard and I switched it on and off in EPICS and Aaron verified that it turned on and off at end X.
