Endress+Hauser Liquistation CSF34 - Additional Functions Overview

Operation Liquistation CSF34
126 Endress+Hauser
3. Define how the device should behave in the hold state. (Configuration options of
Source of data, Measured value and Hold behavior) →  121
Please note that if you select Hold behavior = Freeze , the system not only flags the status
but also actually "freezes" the measured value.
Further information on "Modbus" can be found in the Guideline for Communication via
Modbus, SD01189C
10.5.7 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 sensor inputs and controllers.
2. Select the measured value to be output.
3. Define how the device should behave in the hold state. (Configuration options of
Source of data, Measured value and Hold behavior) →  121
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 digital device variables (DI):
‣
Define the data source.
 You can choose from relays, binary inputs and limit switches.

10.6 Additional functions
10.6.1 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

‣
Specify the input or output which is to be the
data source for the limit switch.
The sources of data on offer depend on your
device version.
You can choose from connected sensors, binary
inputs, fieldbus signals, mathematical functions,
controllers and sets for measuring range
switching.
