UNIVERSAL REGULATOR
The universal controller allows the use to implement some
speci
fi
c functionalities, that are not supported by original
Ventus applications.
The structure of the universal controller contains of two
main blocks:
comparator
– to check the relation between two signals
(can be selected from the program variables or from
universal analog input)
HMI ADVANCED
logic block
– the output from the comparator can be
processed by a logic function with another binary value
(from the program or from the binary input)
the binary output
– can do simple on/off control to
external actuators via universal relay 1 or 2
44 < 50 AND Off = Off – current status line, shows all
Input values, all functions and resulting output
Signal source
– select signal source to be compared with
a reference in comparator block
