Hi Adrian,

camonitor does work with array PVs, so if camonitor is not working then the problem is probably the IOC.

Here is an example of a waveform record that is updating quickly.  The-#100 means only read the first 100 array elements.

However, the problem could be EPICS_CA_,MAX_ARRAY_BYTES.

How large is the array, and what exactly do you see when you type the camonitor command?

Hi Mark,

I've used caget to confirm the correct, and updated, values of my PV (camonitor doesn't work with array PV... I don't know the reason).

If the problem is with CSS, do you have any idea?

Thanks, Adrián.

Hi Adrian,

The first thing to do is to run camonitor from EPICS base on the PV and see if that is updating when it should.  If it does then your problem is with CSS.  If it does not then your problem is the IOC.

Subject: Array PV doesn't update in CSS BOY

Hi, I have an Asyn driver and one of the PV (asynInt32ArrayIn) doesn't update in CSS BOY.
If you run the opi, the PV gets values but never update them again ( unless the opi is updated) .

I attach the PV in .db file:
record(waveform, "$(user):DInILKArrayPreRdbk")
{
field(DTYP, "asynInt32ArrayIn")
field(INP  ,"@asyn($(PORT),$(ADDR),$(TIMEOUT))DInILKArrayPre")
field(SCAN ,"I/O Intr")
field(FTVL, "ULONG")
field(NELM, "512")
field(PINI, "YES")
field(DESC ,"Interlock status array")
}

This PV is used by a widget, which runs a script, being my PV an 'input PV'.

Can anyone help me with this?

Thanks, Adrián.
