Logic functions | Logic functions parameters
Type of logic function
It is possible to be define which logical operation is to be executed for each logic
function. This parameter is only visible if the logic functions have been enabled on
the "General" parameter page.
Logic gate: The logic function works as a Boolean logic gate with optionally 1 ... 4 in-
puts and one output.
Converter (1 bit -> 1 byte): The logic function is configured as a converter. The con-
verter has a 1-bit input and a 1-byte output and also a disabling object. ON / OFF
telegrams can be converted to preconfigured values. The disabling object is able to
deactivate the converter.
Disabling element (Filtering/Time): The logic function is configured as a disabling
element. The disabling element has a 1-bit input and a 1-bit output. This logic func-
tion can delay input signals depending on the state (ON or OFF) and output them
filtered at the output. A disabling object is also available, which can be used to deac-
tivate the disabling element.
Comparator: The logic function works as a comparator with an input whose data
format can be parameterised, and with a 1-bit output to output the result of the com-
parison operation. The reference function and the reference value are configured in
the ETS.
Limit value switch with hysteresis: The logic function acts like a limit switch with hys-
teresis. An input with a configurable data format and a 1-bit output are available. The
hysteresis is determined by an upper and lower threshold. The threshold values can
be parameterised in the ETS. The input value is compared with the threshold values.
The command at the output (ON / OFF) upon exceeding or falling below the con-
figured threshold values can be configured.
