Thanks every body's study, my logical was shown in attached pdf. I have some group device, I design to use structured program to call same function devices. I just tell the FUNCTIONs() the first device and NUMBER of this device, then use Pointer (ptrArr[0..0] AT structure UDT) to access them. the work of programming will be less and program is eay to be read. SO I want to copy the same logic and structure from S7400 to S71500. So I will continue to study how to realize it. Thanks again for every body's helpful studying.
