Overview

The status of input signals for normal inputs are read and stored in I/O memory during the I/O refresh
period in the same way as it is for Input Units. The input time constant (ON/OFF response time) can
also be set.
Bits 00 to 09 of CIO 2960 and CIO 2962 can be allocated as normal inputs.
Select the inputs in the PLC Setup.
