Re: sequencer and registrars

Wow, good call!  Thanks a bunch.  I'm seeing the messages now (which just means I have some other things to figure out, but they're code related and not sequencer).  One of the channels had a typo during its assign command in the sequencer program source code.

I think you just have a disconnected channel, perhaps due to a typo.



Type the following command at the iocsh:



seqChanShow pxlCooling "-"



That will show you a list of all channels that have not connected.

Well, actually, the program compiled but the sequencer program doesn't seem to be loading.  Below is everything the IOC says when running st.cmd.  There should be some messages I built into the .stt file to say when a state is entered (including one right as the first state occurs), but all I get is:
numMonitoredChans 0 firstMonitorCount 0 assignCount 7 firstConnectCount 6
numMonitoredChans 0 firstMonitorCount 0 assignCount 7 firstConnectCount 6
enumMonitoredChans 0 firstMonitorCount 0 assignCount 7 firstConnectCount 6

I've included the full read out when the IOC starts below.  If anyone has any ideas as to what may be the problem, I'd appreciate the help.  The cas warnings are fairly common and I've seen them in other IOCs without causing problems.

If your SNL program begins with a line like:

Then your registrar command is not quite right.  Rather than this:

registrar(pxlCooling_registrar)

it should be

registrar(pxlCoolingRegistrar)

Subject: sequencer and registrars

Hello all,
I'm adapting an IOC that reads text files and assigns the values in them to epics variables for a new system.  It uses sequencer and I don't think I'm setting up the registrar correctly in the dbd file...  I'm not very familiar with sequencer save for the .stt files build the binaries.  The old IOC was for a bunch of gas pressure and flow monitor variables for the time of flight detector at STAR.  I'm adapting a copy for a cooling system for a new pixel detector that will be installed soon.
I'm using epics base 3.13.12.1 and sequencer 2.0.12

The registrar in <top>/dbd/pxlCooling.dbd:
registrar(pxlCooling_registrar)

Here is the error I'm getting:
