For service, networking, remote control and more: Communication at every level
The communications possibilities of the Micro PLC SIMATIC S7-200 are unique. The built-in RS 485 interfaces can operate at data transmission rates up to 187.5 kbit/s functioning as follows:
- As a system bus with a maximum of 126 In this capacity, it is possible to network programming devices, SIMATIC HMI products and SIMATIC CPUs without a problem. The integrated PPI protocol is used for pure S7-200 networks supporting multiple masters from a single port. In a network
consisting of other Siemens components (SIMATIC S7-300/400 and SIMATIC HMI,
etc.), the S7-200 CPUs are integrated as MPI slaves.
- In Freeport mode (up to max. 115.2 kbaud) with user-specific protocols (e.g. ASCII protocol).
This means the SIMATIC S7-200 is open for any connected device; for example, it enables connection of a modem, bar- code scanner, PC, non-Siemens PLC and much more.
By means of the USS protocol for drives, as many as 32 Siemens frequency con- verters can be controlled without addi- tional hardware.
- The Modbus RTU Library included in the package also enables connection to a Modbus RTU network as a Master or a Slave.
OPC Driver with PC Access
PC Access is the ideal basis for data ex- change between S7-200 and a connected PC – regardless of the communication link selected (PPI, modem, Ethernet/IT CP). As an OPC Server, PC Access offers you the option of writing or reading
S7-200 data with Microsoft Excel, or any other OPC client application. As an OPC Client, it can be used for ProTool Pro, WinCC flexible RT, Win CC, etc. With capa- bility up to 8 connections, the configura- tion, programming and monitoring can be implemented from a central location, saving both time and money.
The Internet Technology module
CP 243-1 IT also offers you fast access by permitting a simple universal connection of the PLC to different computers by means of FTP, HTTP, JAVA, and e-mail.
The Ethernet module CP 243-1 allows you to access S7-200 process data quickly over Ethernet for archiving or further processing. The configuration support from STEP 7-Micro/WIN ensures simple commissioning and convenient diagnos- tic options.

The software for plug & play
The STEP 7-Micro/WIN programming soft- ware features time-saving and powerful tools – and that means great cost savings in your day-to-day work. Operation of the programming software is the same as standard Windows applications.
Micro/WIN contains all the necessary tools for programming the entire
S7-200 range of controllers. You have the powerful SIMATIC instruction set at your disposal and you can program in accordance with IEC 1131.
A host of functions such as Trend Charts and wizards now make programming even easier. And STEP 7-Micro/WIN 4.0 has even more to offer: e.g. segmented data memories, improved handling of the program and command structure or diag- nostic functions such as a user-specific LED configuration error history, and run- time edit and online download.
Programming in the standard editors LAD, FBD and STL – and it‘s easy to change between them.

Real-time response
The advanced technology down to the last detail ensures our CPUs deliver excel- lent real-time response rates:
- 4 or 6 independent hardware counters, each with 30 kHz, 2 x 200 kHz with a CPU 224 XP, e.g. for precise path moni- toring with incremental encoders or for high-speed counting of process events
- 4 independent alarm inputs, input filter time 0.2 ms to program action – for maximum process safety
- Pulse-capturing function for signals
> 0.2 ms for fast events from the appli- cation
- 2 pulse outputs, each 20 kHz, or 2 x 100 kHz with CPU 224 XP with pulse-width modulation and pulse-
no-pulse setpoint – e.g. for controlling stepper motors
- 2 timed interrupts starting at 1 ms and adjustable in increments of 1 ms – for bumpless control of rapidly changing processes
- Fast analog inputs – signal conversion with 25 µs, 12-bit resolution
- Real-time clock
Timed interrupts
- Between 1 and 255 ms, with a resolu- tion of 1 ms
- For example: it is possible to record and process signals on screw insertion machine at 3000 RPM after just a quar- ter turn. This enables very precise re- cording, for instance, of tightening tor- ques to ensure optimum fastening of the screw.
Fast counters
- Operating independently of each other, of other operations and of the program cycle
- Interrupt triggering when user select- able counted values are reached – reac- tion time from the detection of an input signal to switching of an output is
300 µs
- 4-edge evaluation when incremental position encoders are used for exact positioning
Alarm inputs
- 4 independent inputs
- For registering signals in rapid succession
- Response time of 200 µs–500 µs for sig- nal detection/300 µs for signal output
- Response to positive-going and/or neg- ative-going signal edge
- 16 interrupts in one queue de- pending on prioritization

SITOP smart – optimally matched to SIMATIC S7-200
SITOP smart is one of the narrowest DIN rail mounted power supply units and ex- hibits an impressive overload behavior. Even high loads can be switched on with- out any problems. Nominal outputs of continuous 120 percent position the power supplies as the most reliable of their class. Numerous certifications sim- plify their universal and worldwide use, as well as their deployment under haz- ardous conditions.
For tough customers: SIPLUS extreme Operating under extreme conditions? No problem! If you have to operate your system in an extended temperature range, require added condensation pro- tection or demand other voltage ratings, then SIPLUS extreme is the solution for you. It lets you adapt your CPUs to your special requirements.
Memory cartridge
EEPROM memory modules
A small optional EEPROM memory module can save you a lot of time and cost. It makes it very easy to copy, update or exchange your user program on the device. And if necessary, you can use this module to send a program quickly and inexpensively to your customers. You just shut off the power, plug in the module, turn it all back on – and the program is instantly up- dated. Whether project documentation, recipe handling or data logging – our memory mod- ules are available with 64 KB or 256 KB.
Available options
Project documentation
- Bitmap files, PDF files, DOC files
- Complete STEP 7-Micro/WIN projects can be transferred to the memory card with S7-200 Explorer – giving you onsite access to the current user data at all times even without STEP 7-Micro/WIN
Recipe handling
- Definition and download of the recipes,
e.g. production data, machine parame- ters, etc.
- Better use of memory by occupying the data memory in the CPU with only one recipe: online updating and adaptation
Data logging
- Dynamic storage, e.g. of performance or statistics data and fault or error messages
- Optionally with time stamp
- Log file transferable to PC via S7-200 Explorer
Small and practical
Battery module
To ensure no user data is lost, you can use the optional battery module for long- term backups to extend backup time from the roughly 5 days of internal backup to, in general, a total of 200 days.
Real-time clock
Whether you need to count operating hours, warm up rooms or attach a time stamp to messages: the integrated real- time clock on the S7-200 runs to the minute and to the day via the software according to your settings – even in leap years. Including automatic daylight sav- ing time switchover.
Analog potentiometers
With the integrated analog potentiome- ters on the S7-200, you can optimize the process sequence almost “according to feel” without a PC or HMI. They let you fine-tune the contents of data registries, time values, preassigned counter values or other parameters without meddling with the program. This is a practical way, for example, to change a welding time or delay time quickly and directly.
