Siemens - cpu im 151-7

Friends

I am using SIEMENS CPU 151 IM with HMI OP77B, DI/DO modules for a sequential control of Bag Filter Cleaning device with 90
Solinoid vales. The logic is sequential( 1,3....89, 2,4, ...90) I need to change it to zig zag mode or some other mode as I am using this for 90 SOV for 4 hoppers. I do not have the Software for this CPU and dont know much about this. Can we use STEP7 MiroWinfor this....any suggessions without changing the wiring....

zig sag mode !?
You made me laugh

You need STEP7 (not MicroWin), some hardware that connects via MPI or DP, and preferably the original STEP7 project.

I would contact the original supplier if I were you.

Dear Jesper

Sorry....typing mistake...I mean ZigZag or random mode. Thanks.
