Hello Guys,

Device: Siemens Step 7 5.5 IM151-8 PLC &Festo CPX valve bank w/ CPI Module

I am using a festo valve bank with CPI inputs. The CPI networks has 4 chains 32 inputs on each. On chain one I only had 1 16pt block, then I moved onto chain 2. However I didnt realize that chain one still reserved the 32 inputs. So all my IO on my machine is all offset. In the hardware manager in siemens it brings all the inputs in as 1 group. Byte 50-65. If I could Shuffle it around on a byte level It would save me hours of relabeling.

Thanks,
Kevin
