space-• Can be used both for simple controls and for complex automation tasks
• In stand-alone mode, in networks and within distributed structures
• Suitable for applications where programmable controllers would not have been viable in the past
• W ith outstanding real-time performance and powerful communication (PPI, PROFIBUS-DP, AS-Interface)
• Extremely simple installation, programming and operation
■Application The SIMATIC® S7-200® is a
micro PLC for open-loop and closed-loop control tasks in mechanical engineering and plant engineering It combines maximum automation with minimum cost
SIMATIC S7-200 applications range from replacing relays and contactors to handling complex automation tasks in stand-alone mode, in networks and within distributed configurations
To save costs, the S7-200 is increasingly being employed
in areas that previously required special electronics
• Electrical installationsThe S7-200 features:
• Easy to learn, with special starter packages and manuals
• Uncomplicated operation; powerful, easy-to-use standard instructions and user-friendly programming software reduce
programming to a minimum
• Unequaled real-time features; interrupt functions, high-speed counters and pulse outputs permit application in time-critical processes
• Powerful communication capabilities; the integrated PROFIBUS-DP interface in particular enables the S7-
200 to maximize its performance in distributed automation solutions
Trang 3consists 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
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
pro-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:
a shared data bus with a programming device, PC, TD
200 or OP Direct data change between S7-200 controllers (in each case as a master) with the NETR and NETW commands
ex-MPI network
All CPUs can be connected to
an MPI network (19.2/187.5 kbit/s) via the integrated interface and can then
Fig 1 Communication in PPI mode
Trang 4■Communication (cont.) 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 cond range enable applica-tions such as the following:
millise-• Motor synchronization
• Interrupt-oriented tions
applica-• Coordination of high-speed counting processes

PC/PPI cable can be used
as RS 232/RS 485 adapter
Expansion bus; connection
of expansion modules (only EMs of the 22x series can be used)
• Interrupt inputs; for extremely fast responses to rising or falling edges of process signals
• High-speed counters;
CPU 221/222:
4 high-speed counters (30 kHz);
CPU 224/226:
6 high-speed counters (30 kHz), with parameteriza-ble enable and reset inputs that can be used
simultaneously as up and down counters with two separate inputs and for connecting incremental encoders wtih two pulse sequences (20 kHz) with a 90° offset
Trouble-free expandability through digital and analog expansion modules (EM’s)
• Simulator (optional);
for the simulation of integrated inputs and the testing of user programs
• Pulse outputs;
2 high-frequency pulse outputs (max 20 kHz); For use in positioning tasks and the control of frequency-regulated motors and stepper motors via power circuits
• Real-time clock (for insertion as optional module CPU 221/222);for example for adding time stamps to messages, for registering machine running times or for the time-control
of processes
• EEPROM cartridge (can optionally be inserted); allows rapid program change (even without a programming device) and additional program archiving
• Battery module for long-term buffering; for extending the buffering time to typically
200 days W ithout the battery module, user data (e.g memory bit statuses, data blocks, timers, counters) are saved by an internal high-power capacitor for around 5 days The program is always saved in non-volatile memory (maintenance-free) The battery module is inserted into the memory submodule slot
Trang 7- 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
