Hi All, Iam using a Omron CP1L PLC and the P_EQ bit is on all the time , can see why , even if a CMP is not equal to the P_EQ bit is still on

The P_EQ bit must be used immediately after the compare instruction and before any other instruction will set this bit.
After your compare monitor the bits that you are controlling and not the P_EQ bit.

CPM2 and CP1L are different model.
