RE: [EXTERNAL] Basics: mbbi record

Hi,

 

I think you also need to initialize the value fields (ZRVL, ONVL, etc), as well as the strings.

 

Cheers,

Matt

Subject: [EXTERNAL] Basics: mbbi record

 

Hi all,

I need some help with basic EPICS records, because I'm just getting "Illegal Value"...

I'm reading from a Modbus TCP device, 16 bit.
Each Bit represents an Input Pin which can be HIGH or LOW. Very Basic.

Bit 7 is 1 because the Input on Pin 7 is HIGH.
-> Decimal Value is 128.

RVAL of the mbbi record is 128.
I read this as "modbus works, correct value recieved"

mbbi should now convert the value und put something in VAL.
it does not.

heres my IOCs output:

and the record:

can anyone tell me why its not converting the RVAL?

thanks,
