Description Defines the function of the switch output. 'Off' The switch output is always open (non-
conductive) 'On' The switch output is always closed (conductive). 'Diagnostic behavior' The
switch output is normally closed and is only opened if a diagnostic event is present. 'Limit'
The switch output is normally closed and is only opened if a measured variable exceeds a
defined limit. 'Digital output' The switch output is controlled by one of the digital output
blocks of the device.

Additional information Meaning of the options
• Off
The output is always open (non-conductive).
• On
The output is always closed (conductive).
• Diagnostic behavior
The output is normally closed and is only opened if a diagnostic event is present. The
Assign diagnostic behavior parameter (→  172) determines for which type of event
the output is opened.
• Limit
The output is normally closed and is only opened if a measured variable exceeds or falls
below a defined limit. The limit values are defined by the following parameters:
– Assign limit (→  172)
– Switch-on value (→  173)
– Switch-off value (→  174)
• Digital Output
The switching state of the output tracks the output value of a DI function block. The
function block is selected in the Assign status parameter (→  172).
The Off and On options can be used to simulate the switch output.
