When a 3100 clock is being set, the current HMI date and time as displayed above,
are copied into the 3100 device shown above to the right. It will advance the 3100
clock a few seconds if necessary so that the net result is close to the HMI time,
however during the process, it continuously retrieves the latest HMI time. If the
minute, hour or date is within thirty to fifteen seconds of r
until the rollover occurs, and then applies the set-ahead principle just mentioned.
When a clock is done, it can be as much as five seconds behind the HMI due to the
number of polls of the 3100 clock needed to validate; and this does cause some
latency.
4) When all clocks are being set, the process marches through all 3100 devices on the
bus that are in a proper state to accept clock changes; hence it is possible that all 3100
clocks on the bus are not changed. This is a very efficient way to set 100’s of clocks.
