I
n the RME1-TC each one of the thermocouple inputs, matches with one Modbus TCP Holding
Register. This way , once the communication has been established, data is moved in a
transparent way from the PT100 inputs to the corresponding Modbus TCP address.
Registers from 40.017 up to 40.100 and from 40.106 up to 40.200 and from 40.209 to 40.248
are reserved bank of memory.
Registers from 40.001 up to 40.016 are read only and show information about each input status.
Registers from 40.101 up to 40.105 show information about the device (read only).
Registers from 40.201 up to 40.208 and from 40.249 to 40.272 are read/write registers and
store the information about the analog inputs configuration.
