The ET 200 CPU Distributed Controllers combine a compact design with flexibility. The Distributed Controllers are the perfect solution for standard and failsafe, in particular in the medium-performance range for machines with distributed intelligence or series machines with little available space. In addition to the SIMATIC ET 200SP CPUs and the new PC-based SIMATIC ET 200SP Open Controller, you also have the choice of the proven SIMATIC ET 200S and ET 200pro CPUs when deciding on the distributed controller for your application.
ET 200SP CPU:
SIMATIC ET 200SP is the new generation of distributed
I/O. CPUs with PROFINET connection are available for SIMATIC ET 200SP. The functionality of the CPUs corre- sponds to that of the S7-1500. Various connection tech- niques can be realized thanks to the 3 integrated Ethernet ports. Thanks to the I-Device functionality, connection to a higher-level CPU can be implemented in exactly the same way as with a standard interface module. The fail- safe ET 200SP CPUs enable the processing of standard and safety programs. They are certified according to EN 61508 (2nd Edition) for functional safety and are suitable for use in safety-relevant applications up to SIL 3 according to
IEC 62061 and PL e according to ISO 13849.
ET 200SP PC Open Controller:
The SIMATIC ET 200SP Open Controller is the first control-
ler of this type to combine the functions of a PC-based software controller with visualization, PC applications and central I/Os (input/output) in a compact device.
The software controller is operated independently of Win- dows and thus offers a high level of system availability: this facilitates the controller‘s rapid start-up and enables Windows updates and reboot during ongoing operation.
ET 200pro:
The SIMATIC ET 200pro is an especially small, extremely
rugged and high-performance I/O system with IP65/67 degree of protection. It also features interface modules for connecting to PROFINET or PROFIBUS with standard as well as fail-safe functionality. A comprehensive range of modules is also available. In addition to power modules and digital and analog I/O modules, there is also a motor starter and an RFID module. Due to its rugged design, the ET 200pro can also be used when mechanical load is high.
