Fieldbus control with embedded fieldbus 333

DCU communication profile
Because the DCU profile extends the control and status interface to 32 bits, two
different signals are needed for both the Control words (
0301 and 0302 ) and Status
words ( 0303 and 0304 ).
Control words
The following tables describe the Control word content for the DCU profile.
DCU profile Control word, parameter 0301 FB CMD WORD 1
Bit Name Value Information
0 STOP 1 Stop according to either the stop mode parameter ( 2102 ) or
the stop mode requests (bits 7, 8 and 9).
Note: Simultaneous STOP and START commands result in
a stop command.
0 No operation
1 START 1 Start
Note: Simultaneous STOP and START commands result in
a stop command.
0 No operation
2 REVERSE 1 Reverse direction. The direction is defined by using the
XOR operation on bit 2 and 31 (= sign of the reference)
values.
0 Forward direction
3 LOCAL 1 Enter local control mode.
0 Enter external control mode.
4 RESET -> 1 Reset.
other No operation
5 EXT2 1 Switch to external control EXT2.
0 Switch to external control EXT1.
6 RUN_DISABLE 1 Activate Run disable.
0 Activate Run enable.
7 STPMODE_R 1 Stop along currently active deceleration ramp (bit 10). Bit 0
value must be 1 (
STOP ).
0 No operation
8 STPMODE_EM 1 Emergency stop. Bit 0 value must be 1 ( STOP ).
0 No operation
9 STPMODE_C 1 Coast to stop. Bit 0 value must be 1 ( STOP ).
0 No operation
10 RAMP_2 1 Use acceleration/deceleration ramp pair 2 (defined by
parameters
2205 … 2207 ).
0 Use acceleration/deceleration ramp pair 1 (defined by
parameters
2202 … 2204 ).
