internal as external a PT100 is connected.
15.3.1 THE COMMUNICATION MODULE
Communication of the TCU with the expansion modules is always with the communication module via
the M&C bus. This is therefore the base module for all other modules.
The TCU or CSS-VC.. and communication module are connected via RJ45 sockets.
On the communication module there are the temperature sensor ports (PT100 or thermocouples E, J,
T, K, N) of the temperature controller module.
