Service 20: Read PLC clock – partner station
When performing this service, the clock data for station B,
increased by the “time_adjust” value, is relayed to station A
and output at the “rec_clock” function block output of
station A.
Use it in conjunction with the function block “lock_time”
input and you can define whether station A clock time is to
be synchronised.
“lock_time” = 1:Read PLC clock station B
The clock data of station B is increased by the “time_adjust”
value (of station A) and applied to the “rec_clock” function
block output of station A.
