Does cFP-TC120-8channels need PIN 20 of BackPlane?

I have broken the PIN Number 20 of Slot1 of the the BackPlane, but the cFP-TC120-8 works fine in that slot.

Could there be any impact?

Thank you.

Hello,

The first line on page 4 of the manual for this device states "The COM terminals of all the channels are internally connected and are connected to the terminals labeled C on the terminal base."  Therefore, the cFP-TC120-8 will work fine in that slot with #20 missing.  You can use any of the other COM pins or the C terminal connection in the terminal block (there are two of them). Pin #20 is COM (ground) for channel 1.
