Display of the PNO identification number which was entered during parameterization
in DIGSI for GlobalSection.DP_IdentNo (ref. to chap. 2.1.1).
Address of the PROFIBUS-DP master which sent the Set Prm and Chk Cfg messages
for the PROFIBUS-DP slave (and which is still in DATA_EXCHANGE mode with the
PROFIBUS-DP slave).
If the PROFIBUS-DP slave is not in status DATA_EXCHG then the displayed address
indicates the master which sent the Set Prm and Chk Cfg messages for the slave last.
A 'l' (lower case character 'L') in the last column is added in this situation, e.g.:
Master: 100
If the PROFIBUS-DP slave has not received the Set Prm and Chk Cfg messages yet,
then this is shown with:
Master: -
Display of the baud rate determined by automatic baud rate recognition.
If a communication break occurs during the data exchange between the PROFIBUS-
DP master and slave then the baud rate recognized last is shown furthermore.
A 'l' (lower case character 'L') in the last column is added in this situation, e.g.:
Baudr.: 1.5 MB/s
If (after switching on the device) no baud rate was recognized yet, then this is shown
with:
Baudr.: -
Watchdog time in milliseconds which was submitted by the PROFIBUS-DP master
with the Set Prm message to the PROFIBUS-DP slave for response monitoring.
If response monitoring is deactivated for this slave in the PROFIBUS-DP master then
this is indicated with:
SlvWDT: OFF
Note:
Response monitoring has to be activated for the slave in the PROFIBUS-DP master
if the tagging "SysIntErr" (ref. to chap. 2.3.1) shall be evaluated in the SIPRO-
TEC device in case of communication break.
If the PROFIBUS-DP slave is not in status DATA_EXCHG then the last received
watchdog time is displayed.
A 'l' (lower case character 'L') in the last column is added in this situation, e.g.:
SlvWDT: 70 ms
If the PROFIBUS-DP slave has not received the Set Prm and Chk Cfg messages yet,
then this is shown with:
SlvWDT: -
