Experimental Physics and
Industrial Control System

I have an application running on an IOC.   This application reads setup information for an experiment out of a file and then does a ca_put (C language call on IOC) to put values into record fields.  I was recently trying to do a put to the INPC field of a record (gppd0A:GasC:g1calc.INPC) and keep getting an ECA_PUTFAIL error on the ca_put.  The associated ca_search seems to go fine.  Also, caput (extensions program on the host) has no problem putting values into this field. 

 

When I switch the database to have an ai record feed the INPC and do a caput to the ai record (gppd0A:GasC:gas1tol) I have no problems. 

 

Does anyone have any ideas of why the first method does not work?

 

Thanks,
