DescriptionName / Range /
Selection
No.
Mode 0 / uint16Defines the mapping between parameters and holding
registers in the 400101…465535 Modbus register range.
Changes to this parameter take effect after the control
unit is rebooted or the new settings validated by
parameter 58.6 Communication control.
Addressing mode58.33
016-bit values (groups 1…99, indexes 1…99):
Register address = 400000 + 100 × parameter group
+ parameter index. For example, parameter 22.80 would
be mapped to register 400000 + 2200 + 80 = 402280.
32-bit values (groups 1…99, indexes 1…99):
Register address = 420000 + 200 × parameter group
+ 2 × parameter index. For example, parameter 22.80
would be mapped to register 420000 + 4400 + 160 =
424560.
Mode 0
116-bit values (groups 1…255, indexes 1…255):
Register address = 400000 + 256 × parameter group
+ parameter index. For example, parameter 22.80 would
be mapped to register 400000 + 5632 + 80 = 405712.
Mode 1
232-bit values (groups 1…127, indexes 1…255):
Register address = 400000 + 512 × parameter group +
2 × parameter index. For example, parameter 22.80
would be mapped to register 400000 + 11264 + 160 =
411424.
Mode 2
LO-HI / uint16Selects in which order 16-bit registers of 32-bit
parameters are transferred.
For each register, the first byte contains the high order
byte and the second byte contains the low order byte.
Changes to this parameter take effect after the control
unit is rebooted or the new settings validated by
parameter 58.6 Communication control.
Word order58.34
0The first register contains the high order word, the
second contains the low order word.
HI-LO
1The first register contains the low order word, the
second contains the high order word.
LO-HI
- / uint16Activates fieldbus communication monitoring
separately for each control location (see section Local
control vs. external control (page 23)).
The parameter is primarily intended for monitoring the
communication with EFB when it is connected to the
application program and not selected as a control
source by drive parameters.
