Alarm State
– the state of the input that is considered an alarm (
Open
– open
state,
Short
– closed state,
Any Change
– the event is generated in case of any
input change).
Current State
– current input state.
5.3.34.2 Relay outputs
Special Function → Inputs/Outputs
The expansion board may have 1 or 2 relay outputs
Attention:
PLC-02 relay output is low-current, use external relay elements
to connect a powerful load.
Figure 5.3.34.2 Configuring the relay output
For each output, you can set the
Initial State
, that is, the state of the output
immediately after the switch is turned on.
5.3.34.3 Logic
Special Function → Inputs/Outputs
The switch can operate as a simple logic controller. A certain output behavior
can be set for the inputs triggering.
Event is the event in which the condition is triggered. Check boxes to select the list of
events that will affect the output. If at least one of the selected events is executed (the
rule of logical "OR" is valid), the relay output is transferred to the
Action
state. If
none of the events occur, the output is in the inverse state.
The
Action
state can be:
Open
– relay outputs are open
Short
– relay outputs are closed
Impulse
– relay outputs change their state to inverse for 10 seconds, then
switch back to the initial state.
