SIMATIC TDC and FM 458-1 DP are SIMATIC control systems and cover the top performance range. Their application area comprises

• Extremely fast response, computing and/or
• Closed-loop control with maximum precision (minimum sampling time: 100 µs)

SIMATIC control systems are freely configurable with STEP 7 and the engineering tools CFC and SFC. Configuring requires the block library of the D7-SYS add-on package.

FM 458-1 DP application module

The FM458-1 DP application module enables high-speed calculation and control in the S7-400 system:

• Rapid I/O access by using expansion modules
• Isochronous PROFIBUS DP interface onboard

SIMATIC TDC

The multi-processor automation system SIMATIC TDC (Rack Based) has been specially designed for complex closed-loop control and computing tasks in plant construction and offers computing power almost without limits.
