When using the delays, ensure that the time delays can be retriggered. Thus, in the case of
"Transmission behaviour for logic 1", a "1" telegram on a gate input always causes a restart
of the time delay. A "0" state on a gate output in "Transmission behaviour for logic 0"
retriggers the switch-off delay each time. Consequently, input states are only evaluated and
output states are transmitted to the bus as a telegram only once the time delays have
elapsed completely.
This should be observed particularly when input states are sent cyclically to the gate. For a
combination of cyclic transmission and delays, the delay times must always be set smaller
than the times for the cyclic transmission.
o
In the parameter "Transmit output object(s) cyclically", set whether, and if yes, in which
time interval the output object or output objects should be sent.
On the parameter page "Logic gate -> Logic gate X -> Inputs" (the following settings can be
made for each of the max. 4 inputs)...
o
In the parameter "Connection", define whether an internal or external input value should be
assigned. If an "internal input value" should be selected for the input, select the value from
the list of all internal 1-bit values.
o
Define the "behaviour" of the input. A normal or inverted evaluation can be defined.
On the parameter page "Logic gate -> Logic gate X -> Outputs" (the following settings can be
made for each of the possible outputs)...
o
Set the parameter "Switching command for logic 0 / 1" for 1-bit outputs and "Value for logic
0 / 1" for 1-byte outputs.
The logic gate has been completely parameterised.
