I need the assistance of someone who is intimately familiar with TISOFT. I am programming a "new" Siemens 545-1105 PLC and was fortunate enough to find the tisoft programming software v6.7, the programming cable, and a laptop that I can run DOS on and has a serial port. I am trying to download the program that I have into the PLC I believe everything is working fine. I can run Tisoft and when I goto Offline mode I see the ladder logic. When I goto Online mode, I get a screen with a bunch of -----(NOP)-'s. So how do I get the ladder logic from the Offline program into the PLC? I have tried going through all the Configuration menu's in On-line mode, but I have not been able to get the program into the PLC. Best Regards, Andrew
