†Note: The presence of 'OCN1' and 'OCN1PU' signals depends on the operation
characteristic defined with setting [OCN1_Timer], as shown in Table 2.17-5.

PLC monitoring points
OCN1
OCN1PU
○
1 : A pick-up signal is generated instantly when the element operates.
○
2 : No signal due that the PU element is killed. Use 'OCN1' in place of this.
○
3 : A pick-up signal is generated, but delayed with the IDMT characteristic.
○
4 : A pick-up signal is generated instantly.
