1. A module identification arrangement, comprising:
- a functional unit including an identification device; and
a signal processing connection connected to the functional unit via a power supply line and a signal line,wherein, in a normal operation mode, the functional unit receives a supply voltage from the signal processing connection, andwherein, in an identification mode, the signal processing connection does not provide the supply voltage and supplies a polling signal to the functional unit via the signal line, the identification device generating an identification signal as a function of the polling signal, the identification signal indicating a type of the functional unit, the identification device transmitting the identification signal to the signal processing connection via the supply line.

Abstract
An arrangement wherein peripheral modules of a decentralized peripheral system connected to an automation unit can be identified. To do so, the peripheral modules of the decentralized peripheral system are equipped with a device that converts a polling signal sent to it into an identification signal during an identification mode. The arrangement can be used in decentralized peripheral systems of programmable control systems.
