Now if I compile the charts it gives me error that FC750 is not called in OB100. I have deleted my logic in OB100 and compiled the charts. Now the error is gone. After compilation I have added my logic in OB100. At the time of saving it gives me error that it have been compliled in different language. Is this the proper way? What if I save the logic? Will it work properly? What is the proper way if i want to add my own logic in OB100.?

But it's very strange to write all your logic in OB100 as it is executed only one time at start up. It's not a cyclic OB. As from my experience, the safety program should be programmed in a cyclic interrupt OB like OB3x (OB35 for example). Other standard program may be called in FCs / FBs called in OB1. Please do not write code in OB100 except these codes that you really would like to execute at startup. Hope this helps.

I have a little logic (Modbus TCP logic at the initialization) in OB100 and I want to know how can i write it. FC750 is one of the fuction that it creates automatically during compilation. but if we have written any logic in OB100 it gives error. How to write logic in OB100?

Hello, Communication on TCP is not part of safety related program and it is called standard part.Create a function in range reserved for other applications in CFC (Options for compile and download) and initialize all memories you want.Initialization can be done with any language and then import it in CFC if it is in correct range.Then place the function in OB100 or other start-up OBs. More advance scenario can be found HERE. I hope these comments help you, Hamid Hosseini
