Dear all,
I have to control a NI PXI device.
The software is written in LabVIEW using native NI LabVIEW/EPICS
interface,unfortunately it seems to only support a subset of PV properties (no
EGU, limits etc.).
My idea is to write a tiny IOC that maps the "raw" LabView variable (e.g.
PV_NAME_RAW) to a complete EPICS PV (e.g. PV_NAME) with precision, EGU, alarms
and limits.
[My IOC] <--PV_NAME--> [LV Mapper IOC] <--PV_NAME_RAW--> [NI PXI]
The problem is that my PV must be both readable and writable at the same time.
I.e. when I write the PV_NAME variable I want also the PV_NAME_RAW variable to
be updated, and when LabVIEW modifies PV_NAME_RAW value I want PV_NAME to
reflect the change.
How can I define my db in LV Mapper IOC? I'm a bit lost, shall I use an input
record or output record?
So far I only achieved single direction control (either input or output, not
both at the same time).
Thanks for your help.
Luca
