PPI Cable

[bjump 0]

Hey all, I am trying to figure out if I can communicate Modbus and remotely program an S7-200 and keep the same dip switch settings on the PPI cable. Basically, the S7-200 sits behind a modem, which receives modbus commands from a Modicon Momentum via the radio. What I would like to be able to do, is remotely change the port mode on the S7-200 from Modbus to PPI and then program the S7-200 and then switch the port back to Modbus mode. I have figured out ways I am able to switch the port back and forth, but I think the only thing that prevents me from doing this is the dip switch settings on the PPI cable that runs from the modem to the S7. I think they would have to be changed in order to switch from receiving modbus to PPI commands and vice versa. I will continue to research this, but if anyone has any suggestions, I would greatly appreciate it.
