3. Define how the device should behave in the hold state (for sensors). (Configuration
options of Source of data , Measured value and Hold behavior ) →  107
Please note that if you select Hold behavior = Freeze , the system not only flags the status
but also actually "freezes" the measured value.

10.7.5 EtherNet/IP
Specify which process values should be output via EtherNet/IP communication.
You can define a maximum of 16 analog device variables (AI).
1. Define the data source.
 You can choose from the analyzer as well as sensor inputs and controllers.
2. Select the measured value to be output.
3. Define how the device should behave in the hold state (for sensors). (Configuration

4. In the case of controllers, also specify the type of manipulated variable.
Please note that if you select Hold behavior = Freeze , the system not only flags the status
but also actually "freezes" the measured value.
In addition you can define 8 digital device variables (DI):

Define the data source.
 You can choose from relays, binary inputs and limit switches.

10.8 Additional functions
10.8.1 Limit switch
There are different ways to configure a limit switch:
• Assigning a switch-on and switch-off point
• Assigning a switch-on and switch-off delay for a relay
• Setting an alarm threshold and also outputting an error message
• Starting a cleaning function (for sensors)
