Guest Støk Posted August 12, 2004 Report Posted August 12, 2004 Hello Everybody, I've already written a program with what i can control a gsm-modem. This happens with a PLC (S7-315-2DP), with a CP-card. The communication between the CP and modem happens with the ascii-protocol. Now I will use a DP/RS232C Link from Siemens instead of the CP-card. So that the connection between the modem and PLC partly happens with profibus and the rest (short piece) with a seriel RS232C. But i don't know how i must start to realize this. Because profibus has for me still a lot of secrets, so did someone have already some experience with this module (6ES7-158-0AA01-0XA0) or some suggestions to bring it on a good conclusion. Did someone know how i must send and receive data with a PLC the a profibus slave? Greetz Støk Quote
