#H: I/O HeartBeat Off
Configures IP Relay behavior when periodically transmitting input states. It is tied with the
K: Keep
connection
command.
K0
disables periodic state transmission, #K#L#M#N#H have no effect and are inaccessible in
the menu.
K1;H0
enables periodic state transmission only when nothing else is sent (e.g. data from the
serial port).
K1;H1
enables periodic state transmission approximately every 5 seconds regardless of the
serial port communication.
Setup examples
Using the described parameters, each bit can be independently configured either to keep a fixed
value, to synchronize itself with changes at an input, or to invert its state with respect to the state of
an input. Study the following examples:
Output = (X.n =0 Y.n =0 Z.n =0)
– output at logic LOW, configurable only with NVT commands
Output = (Z.n =1)
– output at logic HIGH, configurable only with NVT commands
Output = (X.n=0 Y.n=1 Z.n=0 W.n=0)
– output is an exact copy of the remote input
Output = (X.n=0 Y.n=1 Z.n=0 W.n=1)
– output is an inverted copy of the remote input
Note:
In normal operation, the inputs are sampled every millisecond and a change is registered
whenever the input value differs from the last transmitted value in two consecutive
samples (= the change lasts at least 1.2 to 2.0 ms).
