One additional record will be required, unfortunately, to link up the waveform PV which writes to the PLC with the source PV:
source -> lso -> waveform -> PLC
Where lso the newish long string out record, that is.
lso
This looks like:
record(waveform, "TO_PLC") { field(SCAN, ".5 second") field(DTYP, "asynInt8ArrayOut") field(INP, "@asyn($(PORT),0,1)ADSPORT=851/MAIN.fbLinkedValue2.sPLCInternalValue=") field(FTVL, "CHAR") field(NELM, "80") } record(lso, "LSO_HELPER") { field(DOL, "(SOURCE_PV) CPP MS") field(OMSL, "closed_loop") field(OUT, "TO_PLC PP MS") field(TPRO, 1) }
80, just as a reminder: If no size is specified, TwinCAT assumes 80 characters by default. This could be up to 255, but given EPICS's string limitations I don't really think supporting beyond 80 is really necessary to start with.
