Description

PROFIBUS control word
–
–
–
hex
RO
... is the image of control word STW1.
Note:
The bit assignment can be found as follows:
under the index entry ”Process data in the n–set mode – control words – STW1”
under the index entry ”Process data in the pos mode – control words – STW1” (from SW 2.1)
under the index entry ”Process data in the x–set mode – control words – STW1” (from SW 3.3)
0968
PROFIBUS status word
–
–
–
hex
RO
... is the image of status word ZSW1.
Note:
The bit assignment can be found as follows:
under the index entry ”Process data in the n–set mode – status words – ZSW1”
under the index entry ”Process data in the pos mode – status words – ZSW1” (from SW 2.1)
under the index entry ”Process data in the x–set mode – status words – ZSW1” (from SW 3.3)
0969
Actual time difference
–
–
–
ms
RO
... contains the relative system time since the last time that the drive was powered–up or since
the last counter overflow
1781:17
(from
SW 4.1)
Setpoint source, PROFIBUS process
data
–
–
–
hex
RO
... indicates the source of the process data received via PROFIBUS
The high byte includes a reference to the source device (0xFF for the master, DP address for
a Publisher) and the lower byte includes the offset within the received telegram
(counted in bytes starting with 1).
The following applies:
P1781:0
Number of valid entries
P1781:1
Source of process data 1 (STW1)
P1781:2
Source of process data 2 (PZD2), etc.
1782:17
(from
SW 4.1)
Target offset, PROFIBUS process data
–
–
–
hex
RO
... indicates which offset process data, sent to the master or the subscribers via PROFIBUS,
have in the sent telegram
(counted in bytes starting with 1).
The following applies:
P1782:0
Number of valid entries
P1782:1
Target offset of process data 1 (ZSW1)
P1782:2
Target offset of process data 2 (PZD2), etc.
