Application Module FM 458-1 DP - User Manual
A5E01078222-02 Edition 03.2009
The FM 458-1 DP application module has been designed for high-
performance closed-loop control and technological applications (e.g.
Motion Control) which can be freely configured using CFC and optionally
SFC. It is designed for use in a SIMATIC S7-400 station.
Together with two additional plug-in expansion modules, the FM 458-1
DP allows a large number of high-dynamic applications, especially drive-
related applications to be implemented.
These include, for example, closed-loop torque, speed and position
controls for:
 Converter-fed DC and three-phase drives,
 Winder with closed-loop tension/dancer roll controls, coilers
 Multi-motor drives, "breakproof" electronic shaft
 Complex setpoint inputs for e.g. crosscutters/flying saws,
gearbox/motor test stands
 High dynamic performance hydraulic drives in presses.
Designation
Input/output expansion module EXM 438-1
Communications expansion module EXM 448
Communications expansion module EXM 448-2
The FM can be supplemented by the following expansion modules for
fast process coupling:
 The I/O expansion module EXM 438-1 provides binary and analog I/O
as well as incremental and absolute value encoders.
 The EXM 448 communications expansion module offers an additional
PROFIBUS-DP interface (master or slave). Optionally,
MASTERDRIVES plug-in modules, e.g. SLB for SIMOLINK and SBM2
for higher-resolution multi-turn encoders can be used to increase their
functionality.
A maximum of two expansion modules can be used together with the
FM 458-1 DP application. The following combinations are possible:
All of the possible combinations are permitted.
