I’m trying to use pvput to insert EPICS PV names to the channelName array of a NTMultiChannel. I’ve created the NTMultiChannel with a minimum of fields, just for this first test. The error at the output says
that “:” is not a known token as it is trying to parse the PV name instead of interpreting it as a generic string. I’m using EPICS base R7.0.3.1 both for the server and the clients. $ pvput GMDTest:NTMultiChannel channelName="[abcdefg,hijklmn]" Old : epics:nt/NTMultiChannel:1.0
any[] value string[] channelName [] New : epics:nt/NTMultiChannel:1.0
any[] value string[] channelName ["abcdefg", "hijklmn"] $ pvget GMDTest:NTMultiChannel GMDTest:NTMultiChannel epics:nt/NTMultiChannel:1.0
any[] value string[] channelName ["abcdefg", "hijklmn"] $ pvget GMDTest:NTScalar GMDTest:NTScalar 0 $ pvput GMDTest:NTMultiChannel channelName="[GMDTest:NTScalar]" Old : epics:nt/NTMultiChannel:1.0
any[] value string[] channelName ["abcdefg", "hijklmn"] Unknown token ':' in ":NTScalar]"Error: Unknown token New : epics:nt/NTMultiChannel:1.0
any[] value string[] channelName ["abcdefg", "hijklmn"] $ pvput GMDTest:NTMultiChannel '{"channelName":["GMDTest:NTScalar"]}' JSON syntax not supported by this build. I’ve tried many combinations of single-quotes and double-quotes in different positions of the command. I’ve also tried a scape symbol “\”, but couldn’t make it work.
