Diagram 1: Distinction between short/long operation in the “Switch sensor” function
T L is the period after which a long operation is detected.
Parameter: “Cyclic transmission of object ‘Telegr. switch’”
This parameter is visible if there is no distinction between a short and long
operation.
The object “Telegr. switch” can be sent cyclically e.g. to monitor the life signs
of the sensor.
If the parameter value “always” is selected, the object sends cyclically
on the bus, regardless of its value.
If the parameter value “if ‘switch’ = ON” or “if ‘switch’ = OFF” is set,
only the corresponding object value is sent cyclically.
You can receive further information about the topic “Cyclical sending”
in section 5.3.
Parameter: “Reaction on closing the contact” or
“Reaction on opening the contact”
This parameter is visible if there is no distinction between a short and long
operation. It can be set separately for each pulse edge whether the object
value should be “ON, “OFF”, “TOGGLE” or “no reaction”.
If cyclical sending has been parameterised, it is possible to select the option
“terminate cyclic transmission” so that an operation of the input can stop the
cyclical sending without a new object value being sent.
Parameter: “Telegram is repeated every (‘transmission cycle time’)”
This parameter is visible if cyclical sending has been set.
The transmission cycle time describes the interval between two telegrams
that are sent cyclically.
Transmission cycle time = Base x Factor.
Parameter: “Connected contact type”
This parameter is visible if there is no distinction between a short and long
operation.
It is possible to select whether the contact at the input is a normally closed
contact or a normally opened contact.
