7.4.3. Parameter Monitoring in the ‘Screen Display’
7.5. Analog Inputs (Analog Comparator (A))
Analog voltage inputs vary between 0 and 10 V. ZEN has 2 analog input
points, I4 and I5.
The analog input signal is converted into a BCD value (00.0 to 10.0). The
result can be used in one of the CPU comparators, A0 to A3, and the 4
comparison outputs can be used in the program as input conditions.
7.5.1. Settings in the Ladder Program
The analog comparator input is written in the ladder program edit screen. The
settings are carried out in the parameter settings screen.
