Each CTEL master module controls the data transfer to the decentralised I-port I/O-modules in a CPX
terminal.
In principle, several CTEL master modules can be placed in a CPX terminal.
The number of CTEL master modules that can be placed in a CPX terminal is limited by the
available address space of the CPX terminal of up to 64 bytes of inputs and 64 bytes of
outputs.

and the devices connected to the CTEL master module.
