Status/Firmware ID Array
The starting reference address for this two-word array is set in the PROFIBUS Slave
software configuration. For details, see “Parameters” in chapter 3.
Word Name
Description
1
Slave Status
This word contains the slave status code. The status can be read using the
Get Slave Status COMMREQ (task 3), described on page 4-7. .
2
Firmware ID
Current firmware version running on the Slave module. The Major Revision
number resides in the upper byte and the Minor Revision number resides
in the lower byte of this word.

Bits Meaning
Value
15—12 Baud
Rate
(bps)
0=12MBps, 1=6MBps, 2=3MBps, 3=1.5MBps, 4=500KBps,
5=187.5KBps, 6=93.75Bps, 8=19.2KBps, 9=9.6KBps
11—10
Module State
0=Module is waiting for parameters from Master
1=Module is waiting for configuration from Master
2=Data Exchange is occurring – normal operation
3=Error (either configuration error or module watchdog timeout)
9
On-line
1=Online module firmware is running
0=Offline
8
PLC Cfg
0= Module configuration from PLC CPU is bad
1=Module configuration from PLC CPU is good
7
Run/Stop
0=Stop, 1=Run. This is the state of the PROFIBUS module; it is not the
status of the PLC CPU. If the SYS LED is Green the bit=1, if the SYS
LED is Red or Amber the bit=0
6—0
Error Info
See “Network Parameter Errors”
Network Parameter Errors
The following errors codes may be returned in bits 0—6 in the Slave Status word.
Note: The error code is the numerical value of the bits.

One of the watchdog factors (SlvWdFact1 or SlvWdFact2)
from the master was 0.
