3.3.5.1 Communication objects Switch sensor
communication object name
This communication object is enabled if the parameter Enable communication object "Block" 1-bit has been selected with the
option Yes in Parameter window a: Switch sensor, p. 171.
Using the communication object Block, the input can be blocked or enabled. With activated communication object Block the
inputs are blocked.
When the input is blocked there is fundamentally no reaction to a signal change on the input, but:
Waiting for a long button operation or a minimum signal duration is suspended.
Parameterized Cyclic transmission is not interrupted.
The description of the communication object Switch x is still possible.
If the input state changed during the blocked phase, this leads to immediate sending of the new communication
object value after enabling. If the input state remains the same during the blocking phase, the communication object
value is not sent.
0 = Enable input a
1 = Block input a
This communication object is enabled if the parameter Input a has been selected with the option Switch sensor in Parameter
window Enable inputs a…c, p. 170.
In accordance with the parameter setting, this communication object can be set to ON, OFF, Toggle, Terminate cyclic
transmission or No edge evaluation via actuation of the input. With toggle the previous value, e.g. 1, is toggled directly to the
value 0. The communication object can be sent cyclically, e.g. for lifesign monitoring of the sensor.
The communication object can be written to externally. Thus cyclic sending is interrupted or may not be possible
depending on the parameter setting.
No further communication objects are visible with the setting.
