Control systems - Solutions for highly flexible and dynamic applications

Demanding mechatronic tasks can be solved using the freely configurable application modules that combine a high degree of flexibility, functionality and performance:

FM 458-1 DP for fast and precise calculation and control with S7-400
T400 technology module for demanding drive controls
SIMATIC TDC for solutions in the plant sector

Common features of FM 458, T400 and SIMATIC TDC

The FM 458 application modules, T400 and SIMATIC TDC control system are freely configurable with STEP 7 and CFC and SFC engineering tools. Configuring is simplified with the function block library of the D7-SYS add-on package.

T400 technology module
Integrated into drives MASTERDRIVES DC Master in own rack (stand alone)

FM 458-1 DP application module
High-speed calculation and control For S7-400 systems Rapid direct I/O access by using expansion modules Isochronous mode through onboard PROFIBUS DP

High-Performance SIMATIC TDC automation system
Synchronized multicomputing Up to 20 CPUs per rack Up to 44 racks For large plants, iron and steel works, rolling mills, and power transmission

Block library

The wide range of drive-specific functions used in modern machines are implemented with ready-to-use CFC function blocks. These are included in the library of the D7-SYS add-on package.

D7-SYS contains a number of function blocks that can be combined as required, ranging from simple mathematical or logical operations to complex functions for complete motion control of linear or rotary axes.

A powerful code generator, which is also contained, translates the completed function diagrams into high-speed machine code.

D7-SYS contains the following function block groups:

Control loop blocks
Arithmetic blocks
Input/output blocks
Communication/operation/signaling blocks
Conversion blocks
Logic blocks
Service and diagnostic blocks
SFC blocks
Motion control blocks

Configuring and start-up

Control functions are easily and efficiently configured with CFC (Continous Function Chart). Simply select the technology function blocks from the D7-SYS function block library and connect their inputs and outputs. The function diagrams automatically provide detailed documentation for the created program.

Downloading, start-up and servicing are among the online functions available from STEP 7 and CFC via the central MPI interface.

SFC (Sequential Function Chart) is used if CFC programs are combined with sequential controls.

Using the FB-GEN options package for special applications, customer-specific function blocks can be programmed in C and integrated smoothly into the application. No runtime licenses are required for this purpose.
