4-2 Series 90™-30 PROFIBUS Slave Module User's Manual – August 2004 GFK-2193A
4
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.
Word 1 – Slave Status 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.
Error
Code
Meaning
0 No error
1 ID from master does not match Slave ID
2 Ready Time from Master does not match Slave Ready time
3 Master is requesting Freeze or Sync, which is not supported
by the slave
4 Length of data from master to slave is incorrect
5 Length of data from slave to master is incorrect
6 One of the watchdog factors (SlvWdFact1 or SlvWdFact2)
from the master was 0.
7 Slave watchdog time out (check response timeout)
8 Slave timeout watchdog disabled from master
