Fieldbus Data Mapping (M3.6)
Fieldbus data In/Out mappings provide further information over the fieldbus that is not available in the current
object mappings. Data sent to the fieldbus can be chosen with a parameter ID number, and the data is scaled
to an unsigned 16-bit format according to the format on the keypad. For example, 25.5 on the keypad becomes
255 over the fieldbus data mapping.
The fieldbus data mapping settings are presented in the following table:
Table 43: Fieldbus Data Mapping Settings.

P3.6.1
FB DataOut 1 Sel
0
35000
Output Frequency (1)
852
Defines the data to be sent to the
fieldbus as FB DataOut 1. This is
chosen with the parameter ID.
The data is scaled to unsigned 16-
bit format according to the format
on the keypad.
For example, this parameter is set
to a value of 1 which is Output
Frequency (P2.2.1) ID 1. If the
keypad is displaying 25.5 Hz, then
the data over the FB will be 255.
