The "RING" program has received two successive telegrams from Ring NAME
containing the same process station number.
This means that either a PS has illegally sent two successive telegrams (PS fault), or
two process stations are transmitting with the same number xx.
(Incorrect coding or bad contacts in the relative address matrix card.)
If this occurs only occasionally in a DC Server link, ignore it.
Otherwise check the process station numbering using the GPR report. Finally check and
replace the address matrix card in the associated PS
