5.11.3 Process data description
The process data description defines the content of the process data to be transmitted.
The user can individually assign all the process data words.
The following 6 fieldbus parameters are available for defining the first three process data
words:
• P870 setpoint description PO1
• P871 setpoint description PO2
• P872 setpoint description PO3
• P873 actual value description PI1
• P874 actual value description PI2
• P875 actual value description PI3
If one of the above mentioned parameters is changed, acceptance of process output
data for setpoint processing via fieldbus is automatically disabled. Only when the field-
bus parameter is activated again,
• P876 PO data enable = ON
will the received process output data be processed according to the new actual and set-
point value descriptions.
Process data words 4 to 10 can only be read and written using IPOS
plus®
.

tion of PO data
The parameters
setpoint description POx

data words that the higher-level programmable controller sends via the fieldbus system
