Micro PLC SIMATIC S7-200 September 2000 Extract from Siemens Catalog ST 70 3 SIMATIC S7-200 General ■ Design The SIMATIC S7-200 family consists of the following modules: •4 different basic units in different variants •14 digital and analog expansion modules •2 communications modules for connecting to PROFIBUS and AS-Interface Mechanical features •Rugged, compact plastic housing •Easily accessible wiring and operator control elements protected by front covers Design features •International standards; the SIMATIC S7-200 meets the requirements through compliance with VDE, UL, CSA and FM (Class I, Division 2, hazardous area groups A, B, C and D, T4A) standards. The quality management system used during manufacturing has ISO 9001 certification. ■ Communication The SIMATIC S7-200 offers various communication capabilities: •Point-to-point interface; can be operated in PPI, MPI (slave) mode and in user- programmable interface mode •AS-Interface connection; as master via the CP 243-2 communication processor •Connection to PROFIBUS- DP as slave; via the PROFIBUS-DP module EM 277 PPI network PPI is the communications system integrated in every S7- 200 CPU. Connections for pro- gramming or for human machi- ne interface functionality can be established over a shared twisted-pair cable. The CPUs can communicate with several other CPUs, TDs or OPs simultaneously The data transfer rate is 9.6/ 19.2/187.5 kbit/s. The following can be connected: •PG 720PII, PG 740PIII, PC RI45 PIII Tower programming devices •PCs (AT-compatible), via PC/ PPI cable •TD 200 text display; SIMATIC OP operator panels •SIMATIC S7-200; up to 31 S7-200s can be operated on a shared data bus with a programming device, PC, TD 200 or OP. Direct data ex- change between S7-200 controllers (in each case as a master) with the NETR and NETW commands. MPI network All CPUs can be connected to an MPI network (19.2/187.5 kbit/s) via the integrated interface and can then communicate with SIMATIC S7-300 ® s/S7-400 ® s. The S7- 200 CPUs are slaves in the MPI-network and cannot communicate with each other.

Point-to-point interface, user-programmable interface mode Connection to the RS 232 interface via PC/PPI cable. Data transmission is performed with the CPU in FreePort mode; in the case of the CPU 226, both ports can be operated in FreePort mode. Data exchange takes place using a user-specific, bit-oriented communications protocol (e.g. ASCII protocol or Modbus). Maximum data transmission rate 38.4 kbit/s (adjustable). Point-to-point connections are possible to the following units: • Any data terminal equipment which has a serial interface, e.g. printers, bar-code readers •S7-200 micro PLC; e.g. for simple data exchange between two CPUs AS-Interface The SIMATIC S7-200 is connected to the AS-Interface as a master via the CP 243-2. This increases the number of inputs and outputs appre- ciably: •Up to 31 AS-Interface slaves with up to 248 binary elements PROFIBUS-DP slave PROFIBUS-DP guarantees integrated and uniform communication between all SIMATIC system components while at the same time maintaining an open system. PROFIBUS-DP’s high data transfer rate (up to 12 Mbit/s) over the integrated interface allows the real time features of the S7-200 to be used to their full extend within a distributed system structure. Response times in the millise- cond range enable applica- tions such as the following: •Motor synchronization •Interrupt-oriented applica- tions •Coordination of high-speed counting processes Fig. 3 Communication in user-programmable interface mode Fig. 4 Communication via AS-Interface Fig. 5 Communication via PROFIBUS-DP S7-200 SONAR BERO with int.

Device versions ■ Functions •Extensive set of instructions; A multiplicity of - basic operations such as binary logic operations, result allocation, save, count, create times, load, transfer, compare, shift, rotate, create complement, call sub-program (with local variables) - integrated communication commands (eg. S7-200 communication (Network read NETR, Network write NETW ) or Freeport (Transmit XMT, Receive RCV)) and - enhanced functions such as pulse-duration modulation, pulse sequence function, arith- metic functions, floating point arithmetic, PID closed-loop control, jump functions, loop functions and code conversions simplify the programming task •Counting; user-friendly counting functions in conjunction with the integrated counters und special commands for the High Speed Counter open up new application areas for the user •Interrupt handling; - Edge-triggered interrupts (triggered by either rising or falling edges of process signals at interrupt inputs) permit extremely fast reactions to process inter- rupts - Time-controlled interrupts can be set in at 1 ms incre- ments from 5 ms to 255 ms - Counter interrupts can be triggered when a specified value is reached or if the counter direction changes - Communication interrupts allow the rapid and easy exchange of information with peripheral devices such as printers or bar code readers •Direct interrogation and control of inputs/outputs; Inputs and outputs can also be interrogated and set independently of the cycle. The controller can so react quickly to process events (e.g. direct resetting of outputs when interrupt occurs) •Password protection; the 3-level password protection concept safeguards effec- tively your know-how. The protection concept has the following options for access to the user program: - Full access: The program can be altered as desired. - Read only: The program is protected against unautho- rized alteration. Testing, adjustment of system parameters and copying of the program is allowed. - Complete protection: The program is protected against alteration and un- authorized readout and copying. Adjustment of pa- rameters is allowed. •Test and diagnostic functions; User-friendly functions support testing and diagnostics: the complete program is run over a prede- termined number of cycles and analyzed. Internal parameters such as memory bits, timers or counters are logged at the same time over a maximum of 124 cycles. •”Forcing” of inputs and outputs during test and diagnostic operation; Inputs and outputs can be set independently of cycle and thus permanently, for example to test the user program. •Runtime edit: •During RUN mode, programs can be edited and modified programs can be loaded into the CPU with a mouse click without having to interrupt the running program •Additional mathematical functions, e.g. SIN, COS, TAN, LN, EXP CPU 224, CPU 226 in addi- tion: •Runtime edit: During RUN mode, pro- grams can be edited and modified programs can be loaded into the CPU with a mouse click without having to interrupt the running pro- gram •Additional mathematical functions, e.g. SIN, COS, TAN, LN, EXP ■ Programming The STEP ® 7-Micro/W IN32 V3 programming package permits complete programming of all S7-200- CPUs Note The CPU 22x cannot be programmed using STEP 7- Micro/DOS. For programming via the seri- al interface of the program- ming device/PC, a PC/PPI cable is required. W hen using the STEP 7-Micro/ W in32 V3 programming soft- ware, programming is also possible via the SIMATIC CPs CP 5511 or CP 5611 (see Catalog IK PI) or the MPI interface of the programming device. This increases the maximum permissible transmission rate to 187.5 kbit/s.
