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 binary variables (DI Blocks):
1. Define the data source.
2. Select the limit switch or relay whose status is to be transmitted.
PROFIBUS/PROFINET variables (PROFIBUS/PROFINET → device)
A maximum of 4 analog (AO) and 8 digital (DO) PROFIBUS variables are available as
measured values in the controller, limit switch or current output menus.
Example: Using an AO or DO value as the set point for the controller

1. In the specified menu, define PROFIBUS as the data source.
2. Select the desired analog output (AO) or digital output (DO) as the measured value.
Further information on "PROFIBUS" can be found in the Guideline for Communication
via PROFIBUS, SD01188C
Further information on "PROFINET" can be found in the Guideline for Communication
via PROFINET, SD02490C
10.6.4 Modbus RS485 and Modbus TCP
Specify which process values should be output via Modbus RS485 Communication or via
Modbus TCP.
In the case of Modbus RS485, you can switch between the RTU and the ASCII protocol.
You can define a maximum of 16 device variables.
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

Please note that if you select
Hold behavior
=

, the system not only flags the status
but also actually "freezes" the measured value.

Modbus, SD01189C
10.6.5 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
=
