Example 6: Digital output indicating the READY state to a PLC supervisor – using Inputs A, B, C
This example shows how to activate a digital output based on the logic AND of 3 conditions A,B,C—particularly the
ENABLE input, the condition of constant speed reference achieved, and the “Inverter Ok On” condition.
An additional block applied to f(A,B) and C is used:
