Hi friend, Thank you for your reply. I have attached my program here and could you kindly take a look at it and correct me if I have done anything wrong in the program. The program uses AG_RECV to receive data from an ethernet connection, the PLC receivs and evaluates information byte by byte until the it recognise the end character 03hex. Particularly in the copy ANY-POINTER to TEMP buffer part I am not quite understand. The PLC gives me an error information for SFC 20: 8x23, which means "Range length error when writing a parameter."

As the problem may come from this variable data receiving, please check the following link with description and a sample: How is data with variable message length transferred via the TCP protocol and received by an S7-300 station via the Industrial Ethernet CP? |
