1.1 What is the FM 452?

The FM 452 function module is a single-channel, electronic cam controller and is

used in the S7-400 programmable controller. It supports both rotary and linear

axes. When used for position sensing, you can connect initiators, incremental, or

absolute encoders (SSI). As a slave, the FM 452 can listen in on the SSI frame of

an absolute encoder.

You can use up to a maximum of 128 distance or time cams that you can assign to

32 cam tracks as required. The first 16 cam tracks are output via the digital outputs

on the module. For information about the functions and settings of the cam

controller, please refer to the following chapters.

You can operate several FM 452 modules at the same time. Combinations with

other FM/CP modules are also possible. One typical combination is to use the

module in conjunction with an FM 451 positioning module.
