Function description
The Start-stop function is the equivalent of an electrical latching relay.
Latching relays are also referred to as keep relays, impulse switches or remote control switches.
Each time the button is pressed (= ON pulse signal), there is a change in the switching state at the
"Changeover" input variables, which is saved until the next ON pulse.
Input variables
Enable
General enabling of the function (digital signal ON/OFF)
Changeover
Digital input signal (pulse) for changeover
Switch on
Digital input signal (pulse) only for switching on
Switch off
Digital input signal (pulse) only for switching off
➢ The switch on and switch off input variables are especially suitable for switching several
start-stop functions on or off at the same time. With the next pulse at "Changeover", the
switching state is changed again.
Parameters
No parameters to change
On or Off
Can be manually switched by tapping
Output variables
Result
Status output variable ON/OFF; selection of the output
Inverse result
Inverse status output variable ON/OFF; selection of the output
➢ If Enable is OFF, then both output variables are set to status OFF. If the function is switched
back to Enable ON after Enable OFF, the result will always be OFF and the inverse result
will always be ON. In other words, the last switching state is not saved.
➢ The last switching state is likewise not saved in the event of a power failure or a controller
start.
➢ The start-stop function can also be started and stopped manually from the parameter
menu.
