) : “write-only" variables that can be set to the desired value on Modbus supervision systems but their value cannot be read.
For Carel supervisors, these variables are displayed in the "value" field with "***" symbols unless they are set to a new value. In
these cases, the "value" field indicates the number sent in programming to the probe until the next restart.
