Block 1: Status and parameters of the PROFIBUS-DP slave

Slave
Status
SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
Block 1 of the module-specific information shows parameterization data of the PROFI-
BUS-DP slave of the SIPROTEC device and the communication status with the
PROFIBUS-DP master.
Note:
If no PROFIBUS-DP mapping file was selected during parameterization in DIGSI then
all entries of Block 1 are marked with the sign '-':
Slave : -
Status: -
...
Display of the slave address which was entered during parameterization in DIGSI for
GlobalSection.DP_Addr (ref. to chap. 2.1.1).
Display of the communication status between the PROFIBUS-DP slave and the
PROFIBUS-DP master.
The following status indications are signaled:
Status
BAUD_SEARCH no connection to the PROFIBUS-DP master (line faulty or the like)
BAUD_FOUND the PROFIBUS-DP slave is connected to the bus but it is not addressed by
the PROFIBUS-DP master (and it was never addressed since the last con-
nection break)
PRM_OK the PROFIBUS-DP slave is addressed by the PROFIBUS-DP master, the
Set Prm message was received and is OK, the Chk Cfg message from the
PROFIBUS-DP master is expected (this status often is not displayed be-
cause immediate transition to DATA_EXCHG)
PRM_REQ the PROFIBUS-DP slave was addressed by the master before but is now
no more addressed (parameter change at the master without connection
break or PROFIBUS-DP master software is disabled but lower PROFIBUS
layer is still active)
PRM_FAULT error in Set Prm message (e.g. wrong PNO identification number)
CFG_FAULT error in Chk Cfg message (different number of input/output bytes parame-
terized in the PROFIBUS-DP master compared with the number according
to the selected mapping file in the SIPROTEC device)
CLEAR_DATA PROFIBUS-DP master sends Global Control command CLEAR_DATA
DATA_EXCHG PROFIBUS-DP master and slave are in DATA_EXCHANGE mode
Table 1-2 Communication status indications
Note:
The tagging "SysIntErr" (ref. to chap. 2.3.1) also indicates the status DATA_-
EXCHG (tagging is set) and can be evaluated in the SIPROTEC device.
