597 PROFIBUS: Drive not in synchronism. Supplementary
information: \%X
Cause Supplementary information
0x01:
The master sign–of–life (STW2, bits 12–15) has more consecutive failures
than permitted. The permissible sign–of–life error is specified
using P0879 bit 2–0 (PROFIBUS configuration).
0x02:
The Global Control Telegram to synchronize the clock cycles in operation
has consecutively failed over several consecutive DP clock cycles,
or has violated the time grid, specified by the parameterizing telegram
(refer to times Tdp and Tpllw) over several consecutive DP clock cycles.
If the complete DP communications continuously fails, in addition,
fault 599 is output, at the latest after the watchdog monitoring time specified
when the bus was configured.
Remedy – Check whether communications is briefly or continuously interrupted.
– Check whether the PROFIBUS master can operate in clock cycle
synchronism and the Global Control Telegrams, required for clock cycle
synchronous operation, are output in the equidistant DP clock cycle.
– Check whether clock synchronism has been activated in the bus configuration,
although it is not controlled by the master used.
– Check whether the master sign–of–life (STW2, bits 12–15) is received
and is incremented in the parameterized clock cycle.
