PROFIBUS Communication modules

SIPROTEC PROFIBUS-DP - Communication profile

C53000-L1840-B001-03

PNO-Id Display of the PNO identification number which was entered during parameterization

in DIGSI for GlobalSection.DP_IdentNo (ref. to chap. 2.1.1).

Master 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 l

If the PROFIBUS-DP slave has not received the Set Prm and Chk Cfg messages yet,

then this is shown with:

Master: -

Baudr. 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 l

If (after switching on the device) no baud rate was recognized yet, then this is shown

with:

Baudr.: -

SlvWDT 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

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 l

If the PROFIBUS-DP slave has not received the Set Prm and Chk Cfg messages yet,

then this is shown with:

SlvWDT: -

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.
