Abstract

A method of initializing a pluggable electrical unit in a modular system that has a base unit and at least one pluggable electrical unit connected via an interface. Each pluggable electrical unit has module electronics and a read-only memory with clearly identifying identifiers. The interface is equipped with a variable resistor in a feed line. The connection between the base unit and the pluggable electrical unit is established initially only partially, and only to the read-only memory, after switching on the power supply to the pluggable electrical unit. After that, the pluggable electrical unit is identified and, in accordance with the identity of the pluggable electrical unit, the full connection or full isolation between the base unit and the pluggable electrical unit is established.
