Hi Guys
I have a S7 PLC and G120 drive system that I need to modify slightly. The modifications needed are to put 2 values into a PID block and then send the value as a speed reference to the G120 drive. the speed is already sent to the drive currently over Profibus but looking at the code I cannot see where I need to index the address. The issues I have is that I have an old XP PG with Step 7 5.4 and no starter installed on it. I am told Siemens no longer provide the download for starter for XP and I am told that I will not be able to see where the addresses are indexed without starter installed. I can program a Siemens PLC with basic ladder logic but I have never done anything with the Profibus or SCL programming which the majority of this program is written in. Do any of you guys know were I could get a version of starter 4.1-4.4 ? If I can't is there a way of me completing this project with the current setup or will I need to buy a whole load of new software ?
The image attached shows the message I get when I try to open the code. It looks like it will prevent me from making any changes to the program at all.
Any advice would be appreciated.
