Expert Functions - Siemens SIMATIC Power Line Booster Operating Instructions Manual

● "Short circuit PL B to PE": The PLB has detected a short circuit between the Powerline
rail "B" and the earth.
● "Short circuit A/B to L": The PLB has detected a short circuit between the Powerline rail
"A" and/or "B" and a line conductor.
A voltage that is dangerous to the touch is present on all Powerline rails and all cables and
plant units connected to them.
Measure: Shut down plant!
● "Overvoltage on PL": This value indicates whether an overvoltage was detected on the
powerline rail instead of the 42 V carrier voltage (Page 29). If "Yes", this may be a cabling
error.
A voltage that is dangerous to the touch is present on all Powerline rails and all cables and
plant units connected to them.
Measure: Shut down plant!
Note that faulty voltages often affect the entire segment and that all slaves in the segment
therefore show the same error.

Expert functions

Expert functions are available on the PLB for diagnostics and commissioning of a Power
Line Booster system. The functions often engage deeply with the system and have a
significant effect on communication. The functions described below may only be executed by
trained personnel and outside of regular production.
Only one expert function can be executed at a time. The other web pages are grayed out.
As soon as an expert function is active on the master, this fact is displayed in the status bar
of the web page with the note "Expert function activated".
All expert settings are not stored retentively in the system and the PLB always resumes its
original configuration after a restart.
