The macros from for xtpico module should be different from those from the alias
The macros from for xtpico module should be different from those from the alias:
record("*", "$(P)$(R_LTC2991)-ValueV1_RBV") {
alias("$(P)$(R_LTC2991)-15vDigVol")
field(DESC, "Digital 15V Voltage")
field(EGU, "V")
alias("$(P)$(R_LTC2991)-15vDigVol")
https://gitlab.esss.lu.se/e3/wrappers/devices/e3-xtpico/-/merge_requests/29#note_58550
My suggestion is to change the alias to:
alias("$(P)$(R)-15vDigVol")
