Application The SIMATIC S7-200 is the micro PLC for open-loop control and closed-loop control tasks in machine and plant construction. It combines the greatest possible automation effect with the lowest costs. SIMATIC S7-200 applications range from replacing relays and contactors to handling complex automation tasks in standalone mode, in networks and within distributed configurations. To save costs, the S7-200 is increasingly being employed in areas that previously required special electronics. Applications include: Design The SIMATIC S7-200 family consists of the following modules: Mechanical features Equipment features Communication The SIMATIC S7-200 provides various possibilities for communication: PPI network PPI is the communication system integrated in every S7-200 CPU. Connections for programming, operation or monitoring can be established over a common two-wire cable. The CPUs can communicate simultaneously with several CPUs, TDs or OPs. Data transmission rates 9.6, 19.2 and 187.5 Kbit/s. The following can be connected: Communication in PPI mode MPI network All CPUs can be connected to an MPI network over the integral interface (19.2/187.5 Kbit/s) and thus communicate with SIMATIC S7-300/S7-400. The S7-200 CPUs are slaves on the network and cannot communicate with each other.

From the small compact unit through the high-performance PLC as far as PC-based Control. SIMATIC controllers are available for every demand and every requirement, in every type and size.They all share the same characteristics of high processing performance in the smallest possible space, ruggedness in the face of the harshest mechanical and climatic conditions, high speed and excellent expansion capability.This graded performance capability is the strength of the SIMATIC family.And in the meantime, the SIMATIC PLC is also performing functions for which you had to use completely differently technology in the past. This makes it all much easier, more compatible and more economical for you.
