Hi, I'd like some basic infos on programming Siemens S7 200 PLC. We use the basic software included in the package : STEP 7 - MICROWIN 32 I wanted to know if in this software, you can run your program and can watch the progress of the cursor on a Grafcet? Also, are there any free alternatives to STEP7 - MICROWIN 32 for programming? If not, can anyone tell me where to find a good E-Book on programming SIEMENS S7 200 PLC with STEP 7 MICROWIN? Thx a lot!
