ZhaoShenjie Posts: 10 Rating: (0)	[:)] First, thanks for every expert answering my question. I think SIMENS build a good discussion way for PLC developing people. And there are so many kind people here. Thanks again. In my case, a FM352-5 works as a coprocessor with a S7-300 CPU. S7-300 CPU gets a bool variable A from SM321, and FM352-5 gets B from itself input port.I want ''A & B'' , then output C (C=A&B)from FM352-5. I want to know how the CPU transfers 'A' to FM352-5, and how FM352-5 gets it , and then makes A & B? Another question, I have Step7 V5.3, FM352-5 configure software and PLC-SIM ,but no FM352-5 module.how can I model(simulate) the FM352-5 in order to help my developments?

You can find this handbook by Siemens on the support sides behind the link: http://support.automation.siemens.com/WW/view/en/9240171 The module is working to the standard S7-program over a I/O-interface, this is described in the handbook. A simulation of this module is so far i know not possible. [:(] But what you can do is reading what the module have for instructions inside and then make a program in STEP7 to simulate it with PLCSIM. [:P] Because a FM352-5 is very fast with his FPA-logic it is only important to check the code. If you have the module there is a possibility to look in the simulate mode to the code.
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
