  1. S7-200 connecting via EM241 module

    Ok, thank you for your answer. When I understand it wright, it is not possible to program via the EM241 module? And it's also not impossible to teset the phonenummer that's confugured in the module. Ok. Than we have to find a PPI cable. But then it's also not possible to go online in the program, because port 0 is also used bij the panel. Gr. Erik
  2. I friend of my bought a machine on a auction with a siemens S7-200 PLC with an EM241 module. We don't have any drawings or PLC program. Now I am trying to connect via the EM241 module. I have connected a 56k modem to my serial port on de desktop. How can I connect to de CPU via the EM241 and a 56K modem? We use microwin, but if is it's necessarily i can use the Simatic S7 software. Do we need a phone number or is there a way to reset the communication to default? When I try to connect microwin say's there is no dialling tone. I hope someone has an answer, because the macine is Turkisch, and we don't understand waht to do to run it. Erik.
