SYNAX200 PPC Link 9-5
DOK-SYNAX*-SY*-07VRS**-PR01-EN-P
Commissioning
First the PPC link and the fibre-optics lengths are parametrized via
SynTop and the PPCs are brought into operating mode.
The active PPC link is displayed on displays H11 or H12 at each PPC
using the parametrized PPC link. (Precisely one link master and several
link slaves).
The H17 and H18 distortion displays must be checked and if necessary
the transmission power of the immediate physical predecessor must be
corrected or the fibre-optics lead checked for any damage.
In the case of a parametrized simple ring (no double ring) the H18
distortion displays will light up. This state is correct.

Fig. 9-7: Error messages with PPC link errors
In such cases, the H11, H12, H17 and H18 displays can be used to locate
the cause.
Causes can be:
• incorrectly set transmission power of primary and secondary rings
• wrong parametrization of PPC link (simple ring, double ring, no PPC
link)
• defective fibre-optics cable.
