Feedback from the ABB E-Clipse Bypass – EFB
Pre-defined feedback
Inputs to the controller (bypass outputs) have pre-defined meanings established by
the protocol. This feedback does not require bypass configuration. The following
table lists a sample of feedback data. For a complete listing, see input word/point/
object listings in the technical data for the appropriate protocol.
0101
Note: As noted above, Modbus provides direct access to all parameters using the
format: 400000 + (group #) * 256 + parameter #.
Example: drive parameter 28.01 is mapped as 40000 + 28 * 256 + 1 = 407169.
