Siemens expands micro PLC line

Alpharetta, Ga. - Siemens Energy & Automation, Inc. released Version 3.2 of its micro PLC programming software, Simatic Step 7 Micro/WIN 32, in conjunction with the release of two new S7-200 expansion modules-EM241 Modem Module and EM253 Position Module.


Alpharetta, Ga. - Siemens Energy & Automation, Inc. released Version 3.2 of its micro PLC programming software, Simatic Step 7 Micro/WIN 32, in conjunction with the release of two new S7-200 expansion modules - EM241 Modem Module and EM253 Position Module.

Micro/WIN32 V3.2 adds configuration wizards for both the EM241 and EM253 modules. Now, using a modem or configuring a motion profile has been reduced to completing the entries on wizards.

EM241 Modem Module brings remote communications to the S7-200 Micro PLC. Four modes are supported: Micro/WIN connection for remote programming and debugging, Modbus master/slave communication, alpha-numeric messaging and numeric paging, and CPU-to-CPU communications.

EM253 Position Module is an S7-200 special function module that generates the pulse trains used for open loop control of the speed and position for either stepper motors or servomotors. It features high-speed control capabilities (up to 200,000 pulses per second) and can handle up to 25 profiles with up to four speed changes per profile. S-Curve profiling allows smooth starting and stopping of motion profiles.

STEP 7 Micro/WIN32 V3.2 is a Microsoft Windows compatible development environment for programming, documentation, machine startup, and maintenance for the company's micro PLCs. Micro/WIN is IEC-61131 compliant and includes Statement List, Ladder, and Function Block Diagram programming languages.
