Note: BI1_CPL~BI12_CPL settings are provided for the BI2A module.
As an example, Figure 5.4-1 shows the binary input circuit of the BI1A in order to help
understand the settings. The BI1A consists of 18 binary input circuits and each circuit has
three settings:
Setting threshold level
Comparison feature for contact chatter
CPL switches (“Delayed pick-up and delayed drop-off signal” and “Logic level
inversion”), used as basis of input signal characteristics.
