Failsafe mode
A failsafe mode can be defined for using the compensation values.
If the status is GOOD or UNCERTAIN, the compensation values transmitted by the
automation system are used. If the status is BAD, the failsafe mode is activated for the use
of the compensation values.
Parameters are available per compensation value to define the failsafe mode: Expert
→ Sensor → External compensation
Fail safe type parameter
• Fail safe value option: The value defined in the Fail safe value parameter is used.
• Fallback value option: The last valid value is used.
• Off option: The failsafe mode is disabled.
Fail safe value parameter
Use this parameter to enter the compensation value which is used if the Fail safe value
option is selected in the Fail safe type parameter.
Digital Output module
Transmit digital output values from the automation system to the measuring device.
Digital output values are used by the automation system to enable and disable device
functions.
Digital output values cyclically transmit discrete output values, including the status, from
the automation system to the measuring device. The discrete output value is transmitted
in the first byte. The second byte contains status information pertaining to the output
value.
Assigned device functions
