Outputting the status of a cleaning function
10.4.3 HART
Specify which device variables should be output via HART communication.
You can define a maximum of 16 device variables:
‣ Define the data source. You can choose from the sensor inputs and the controllers.
‣ From the source, select the measured value that should be output.
‣ Define how the device should behave in a hold state.
‣ The configuration options for "Source of data", "Measured value" and "Hold behavior" are
identical to those described in the "Outputs/Current outputs" section. Please refer to this
section for more information.
‣ Please note that if you select Hold behavior="Freeze", the system not only flags the status but
also actually "freezes" the measured value.
More information is provided in BA00486C "HART communication".
10.4.4 PROFIBUS DP
Device variables (device → PROFIBUS)
Specify which process values should be mapped to the PROFIBUS function blocks and are
thereby available for transmission via PROFIBUS communication.
You can define a maximum of 16 device variables (AI Blocks):
‣ Define the data source.
Choose between sensor inputs, current inputs or mathematical functions whose measured
values should be transmitted.
‣ From the data source, select the measured value to be transmitted.
In addition, you can define 8 binary variables (DI Blocks):
‣ Define the data source.
Select the limit switch or relay whose status should be transmitted.
