Application Module FM 458-1 DP - User Manual  2-3 
A5E01078222-02     Edition 03.2009 
2.1.2  Application and design 
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  Order No. 
Input/output expansion module EXM 438-1  6DD1607-0CA1 
Communications expansion module EXM 448  6DD1607-0EA0 
Communications expansion module EXM 448-2  6DD1607-0EA2 
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.
