2.2.2 Power supply modules
The power supply for gateways and I/O modules is provided by the power supply modules;
therefore, it is not necessary to supply each individual module with a separate voltage.
2.2.3 Electronics modules
The electronics modules contain the I/O-functions of the XI/ON modules (power supply
modules, digital and analog input/output modules, and technology modules).
XN standard electronics modules
The XN standard electronics are plugged onto the base modules and are not directly
connected to the wiring and can be plugged or pulled when the station is being commissioned
or for maintenance purposes, without having to disconnect the field wiring from the base
modules.
