4.1.2 Data types
4.1.3 Parameter list structure
To address parameters via the fieldbus, the following information is important:
• Value range
• Scaling via fieldbus if this differs form the scaling via POSITool.
• Rounding errors via fieldbus, if present.
• Data type
They are specified in the parameter table in the application description.
The fieldbus addresses are specified as hexadecimal numbers. For CANopen
®
and EtherCAT
®
, the index and subindex can be transferred directly. For PROFI-
BUS DP-V1 and PROFINET®, index = PNU and subindex = index. Further details
are in the documentation for the fieldbus interface connection (see section1.3
Other manuals).
