STEP 7 LITE Need help for a ladder diagram.

[ivo.maenen]

My teacher told me to build the circuit in Alpha programmer of Mitsubishi cause its easy and then use STEP 7 to transfer the circuit in LADDER diagram so i can upload the ladder diagram on a s7200 plc we have in our laboratory!

I also worked with Alpha from Mitsubishi and I'm not that keen on it. There are other simulationprograms who are better. One of my favourites is the software from Vipa. It's a free download and has the same instructions like the software from siemens for S7-300/400. This is still different software from the S7-200 series. But you can program direct in ladder. You will need to make adjustments for instructions on the timers and counters, but using the Alpha this is something what you also will need to do.
