Description
SIMATIC S7-400, EXM 438-1 I/O extension for FM 458 4x analog outputs 16-bit EXM 438-1 not spare part-compatible for EXM4386DD16070CA1_datasheet_en
Overview
SIMATIC FM 458-1 DP integrated in SIMATIC S7-400
- Designed for high-performance and user-configurable closed-loop control tasks in the SIMATIC S7-400.
- Can be adapted to individual requirements as required, such as:
Controlling, computing, closed-loop control as well as motion control. Can therefore be used flexibly for a wide variety of applications. - Extensive library with approx. 300 function blocks:
E.g. simple functions such as AND, ADD and OR through to complex GMC (general motion control) blocks as virtual master or gear functions. - User-friendly graphical configuration with the SIMATIC engineering tool CFC (Continuous Function Chart) and the D7-SYS add-on software package:
Optimum code generation by the compiler, therefore SCL is not required. - PROFIBUS DP interface onboard.
SIMATIC FM 458-1 DP is based on more than 15 years experience with high-performance control systems and combines this know-how with the advantages of SIMATIC – the leading automation system for decades. In contrast to other function modules with static structure
Application
The FM 458-1 DP application module from the SIMATIC S7-400 system is available for mechatronic solutions with high cycle rates, especially in the production, packaging and printing machine industries.
Together with two additional plug-on expansion modules, the FM 458-1 DP permits a wide range of highly dynamic applications particularly at the drive level.
For example, torque, speed, positioning and position controls can be implemented for:
- Converter-fed DC and three-phase drives
- Winders with tension/dancer controls, coilers
- Multimotor drives, “unbreakable” electrical shaft
- Complex setpoint inputs, e.g., for cross cutters/flying saws, gearbox/motor test stands
- Hydraulic drives with high dynamic response in presses
