Dear Ralph,
Thanks for the comment.

THis is the current setpoint of a power suplly.
The IOC db file contains this information
record(ai,"LEBT:PS:STH1:OPER:CurrSP"){
field(INP,"LV:LEBT:PS:STH1:OPER:CurrSP CP")
field(DESC,"PS EXT Voltage")
field(DESC, "LEBT STH1 Current SP")
}
I guess that I am trying to change the INP field which has no access
permission according to the Record Reference Manual, isn't it?
In this case how is possible that the value can be changed with the CSS GUI?
Should have the record a VAL field?
Sorry if they are trivial questions; but I new to EPICS.
