1 S7-200 The micro PLC that offers maximum automation at minimum cost. Extremely simple installation, programming and operation. Large-scale integration, space-saving, powerful. Can be used both for simple controls and for complex automation tasks. All CPUs can be used in stand-alone mode, in networks and within distributed structures. Suitable for applications where programmable controllers would not have been economically viable in the past. With outstanding real-time performance and powerful communication options (PPI, PROFIBUS DP, AS-Interface) 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.

2 Application Baling presses Plaster and cement mixers Ventilation plants Centralized/flange lubricating systems Woodworking machinery Gate controls Hydraulic lifts Conveyor systems Food and beverage industry Laboratories Modem applications (remote monitoring and maintenance) Electrical installations Design The SIMATIC S7-200 family consists of the following modules: 5 basic devices with graded performances in different versions. 15 different digital and analog expansion modules. 2 communications processors for connection to PROFIBUS and AS Interface. Mechanical features Rugged, compact plastic housing. Easily accessible connection and control elements, protected by front flaps. CPU 224 and higher: Removable connection terminals, also for digital expansion modules Page 68 Mar 2008 Siemens ITS

3 Equipment features International standards: SIMATIC S7-200 complies with the standards according to VDE, UL, CSA and FM (Class I, Category 2; Danger zone groups A, B, C and D, T4A). The quality management system used during production is certified according to ISO Communication The SIMATIC S7-200 provides various possibilities for communication: Communication interface: Can be operated in PPI slave, MPI slave and in the freely-programmable interface mode. Connection to AS-Interface: As master via CP communications processor. Connection to PROFIBUS DP as slave: Via PROFIBUS-EM 277. 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 Kbit/s. Page 69 Mar 2008 Siemens ITS

4 The following can be connected: Programming devices: Field PG, Power PG. PCs (AT-compatible), via PC/PPI cable. TD 200 Text Display, TP070 Touch Panel; SIMATIC Operator Panels. SIMATIC S7-200: Max. 31 S7-200 PLCs on a common data line to a PG, PC, TD 200 or OP. Direct data exchange between S7-200 PLCs (in each case as master) and NETR and NETW 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/S The S7-200 CPUs are slaves on the network and cannot communicate with each other.

5 Communication in MPI mode Point-to-point interface, freelyprogrammable interface mode For connection of third-party devices with RS 232 interface via PC/PPI cable. Data transmission is carried out in the freeport mode of the CPU, and both ports of the CPU 226 can be operated in freeport mode. A user-specific, bit-oriented communication protocol is used (e.g. ASCII protocol or Modbus), and the max. data transmission rate is Kbit/s (adjustable). Point-to-point connections are possible to: Any data terminals with serial interface, e.g. printers, barcode readers, modems. S7-200 micro-plc; e.g. for simple data exchange between two CPUs.

6 Communication in programmable interface mode AS-Interface The SIMATIC S7-200 (CPU 22x) is connected as master to the AS-Interface via the CP This significantly increases the number of inputs and outputs: Max. 63 AS-Interface slaves with max. 248 binary elements Page 72 Mar 2008 Siemens ITS

7 PROFIBUS DP slave Totally integrated and uniform communication is guaranteed between all SIMATIC system components over PROFIBUS DP with uniform external openness. The high transmission rate of the PROFIBUS DP (up to max. 12 Mbit/s) permits full utilization of the real-time characteristics of the S7-200 within a distributed plant structure. Response times in the millisecond range permit e.g.: Motor synchronization Alarm-oriented applications Coordination of fast counting processes Page 73 Mar 2008 Siemens ITS

8 Function The S7-200 features: Simplest possible entry level: Special starter packages and prepared exercises speed up the familiarization process. Uncomplicated operation: Powerful, easy-to-use standard instructions and user-friendly programming software keep programming overhead to a minimum. Excellent real-time features: Special system interrupt functions, high-speed counters and signal outputs enable use even with time-critical processes. High-performance communication options: Optional PROFIBUS DP connection particularly allows the S7-200 to fully utilize its capabilities in distributed automation solutions.
