Hi, I want to connect remote station S7 200 with sinaut MD 720-3 GSM/GPRS modem with my lapotop via teleservice using phone network. I make connection due to How do you set up a teleservice connection based on MAS 21 to an S7-200 with MD720-3 via STEP 7 Micro/WIN? When I tried to connect after few seconds appeared message that line is disconnected Reason: Busy!. I called operater on remote station and he told me that all three led on MD720-3 are ON. i tried several time to establish line but without success. In PLC I put my phone number(WDC INIT CLIP)with country code(with +) and area code, too. Have someone idea what would be problem? Thanks in advance. |
