Configuration Support

We love this business so much that we want to try our very best to have you enjoy selecting the components you need from the SIEMENS basket of industrial automation and drives technologies. SIMATIC is the tried and tested basic automation system for solving automation tasks in all sectors comprising standard components in hardware and software that keep all the options open for customized expansions.

The SIMATIC family comprises the following components that complement each other perfectly:

  • Programmable controllers
  • Distributed I/Os
  • Programming devices
  • SIMATIC Software
  • Micro Automation Sets
  • Component Based Automation
  • Machine Vision (see Sensors, Test and Measurement Technology)

SIMATIC S7-200 Micro Programmable Logic Controllers

  • CPU 221 supports 0 Expansion Modules
  • CPU 222 supports 2 Expansion Modules*
  • CPUs 224, 224XP & 226 support 7 Expansion Modules*

*) You must calculate your power budget to determine how much power (or current) the S7-200CPU can provide for your configuration. If theCPU power budget is exceeded, you may not be able to connect the maximum number of modules. See Appendix A in S7-200 System Manual for CPU and expansion module power requirements, and Appendix B to calculate your power budget.

* Terminal connectors are removable on CPU 224, CPU 224XP and CPU 226


  • With Modbus RTU Master Libraries you can now create a Modbus RTU network using Port 0 or Port 1. The S7-200 acts as a Master or Slave on a Modbus RTU network.
  • USS Library for either Port 0 or Port 1 (CPU 224XP and CPU 226) is now available. This allows you to use the USS communications on Port 1 and reserve Port 0 for PPI communications or Freeport communications.

Text Display Units: (See ST 80 Human Machine Interface Systems Catalog Pages 28-46)

The Text Display (TD) is a display device that can be connected to the S7-200. Using the Text Display wizard, you can easily program your S7-200 to display text messages and other data pertaining to your application.

The TD device provides a low cost interface to your application by allowing you to view, monitor, and change the process variables pertaining to your application. The S7-200 product family provides four TD devices:

  • The TD100C has a 4-line text display with 2 font choices.
  • The TD 200C has a 2-line text display with 20 characters per line for a total of 40 characters.
  • The TD 200 has a faceplate which provides four keys with predefined, set-bit functions and allows up to eight set-bit functions.
  • The TD400C can have a 2- or 2 4-line text display depending on your font and character choice.

Operator and Touch Panel Displays:

The OP 73micro and TP 177micro panels are tailored to applications with SIMATIC S7-200 Micro PLC and provide operating and monitoring functions for small-scale machines and plants. Short configuration and commissioning times, and their configuration in WinCC flexible form the highlights of these panels. In addition, these panels support up to 32 configuration languages and five online languages, including the Asian and Cyrillic character sets. The mounting dimensions of the Operator Panel OP 73micro with its graphical 3" display unit are compatible with OP3 and TD 200. Touch Panel TP 177micro replaces the Touch Panel TP 070/TP 170micro. It can be mounted vertically to accommodate additional applications. This feature enables its use even when space is restricted.

Please note the following as you configure your SIEMENS S7-200 PLC:

How do you configure a Modbus slave using the "RCV_341" (FB 121) block?

Please note the following as you configure your SIEMENS S7-300 PLC:

  • CPU racks can accommodate no more than 8 I/O modules
  • Should one (1) remote I/O rack (max) be required and if the distance between the CPU rack and remote I/O rack is no more than 1 meter, you can use IM 365 Interface Module. IM 365 is made up of 2 modules with a 1 meter permanent connecting cable. A 24VDC power supply is not required for a remote I/O rack where an IM 365 is used.
  • Should 1-3 remote I/O racks (max 3) be required and if the distance between the CPU rack and the last remote I/O rack is no more than 10 meters, you can use IM 360 interface module in the CPU rack and IM 361 Interface Module in the remote rack (s). Connecting cables between IM 360 and IM 361 or IM 361 and IM 361 can be purchased in the following lengths: 1 meter, 2.5 meters, 5 meters, and 10 meters
  • Should you be using a Profibus-based CPU such as CPU 315-2 DP and you prefer to have a profibus-based remote I/O rack, you no longer have to worry about the distance between the CPU and remote I/O rack
  • SIEMENS offers many choices for the profibus-based remote I/O racks (see ET 200 Distributed I/O section of IK PI Catalog 2009). The most common are ET 200M (S7-300 based for high density module requirements) and ET 200S (where standard motor starters with motor starter protectors and contactor assembly up to 5.5 kW can be used). Frequency converters ( up to 4.0 kW) can also be completely integrated into the ET 200S I/O system
  • ET 200M: With IM 153-2 High Feature (required for F-technology or the highest performance in conjunction with clock synchronization) Profibus interface smodule or IM 153-4 Profinet interface module (Micro Memory Card with at least 64 KB required), twelve (12) I/O modules can be used in the remote rack. IM 153-4 Profinet interface modules should be used in conjunction with a profinet based S7-300 or S7-400 CPU such as CPU 315-2 PN/DP, or CPU 414-3 PN/DP
