where temp_val1 is a Tcl variable which value is an EPICS PV
and statement is the name of a Tcl procedure:

change::

   pv linkw temp temp_val1
   pv cmon temp statement

to::

   pv linkw temp temp_val1
   pv umon temp statement

"umon" starts channel access monitor(s)
"cmon" clears channel access monitor (s)

[note: the documentation page does not make this clear, it seems]

Dear All,

I am using et_wish as a client to monitor the temperature logged through
EPICS ioc.

as et_wish documentation  i use the following statement to link ioc
process variable and tcl variable as follows
pv linkw temp temp_val1

where temp is tcl process variable and the other is pv of IOC.

when i used
pv cmon temp statement where temp is linked to a label widget on the
GUI, it shows the temperature but does not update as the temperature varies.

Could you please let me know where it has gone wrong ?

Thanks & Regards,

Nalaka
