I tried to perform a simple enabling test of coils using c1susaux2 modbus channels but failed. I'm able to do the enabling of coils using the windows GUI of acromag card but I can not do it when the cards are connected to the computer subnetwork. The issue is two-fold:

• The enable channels such as C1:SUS-LO1_UL_ENABLE are not changing values when their DOL changes a value. In this case, I created a calc channel C1:SUS-LO1_ALL_CALC which takes the AND of all coil's individual CALC channels which are normally used as DOL for the ENABLE channels. But even though the changes are reflected properly to C1:SUS-LO1_ALL_CALC, it does not affect C1:SUS-LO1_UL_ENABLE. See the db files here for more info.
• I tried to directly change the value of C1:SUS-LO1_UL_ENABLE using caput and even though in soft value the channel changes, it does not propagate a change at the output of Acromag card. So my suspicion is that something might be off with the setting of the Acromag card or c1susuaux2.cmd file. I followed this wiki page instructions, but if anyone can find an error, it would be useful.

There's also an issue in reading back the ENABLE_MON channels. Here we suspect that one of the optical isolator box that we have been using might have a short in one of it's output channel. I'll investigate this more tomorrow. Again, the issue is two-fold. The EPICS channel values do not really change. So there is clearly some issue of communicating with the acromag cards.
