Clock synchronous monomaster operation (main application case)
With this operation the drives make high demands on time synchronism
at the bus. Through an isochronously transmitted global control the
master class-1 (e.g.SIMOTION) passes on clock pulse information to the
slaves (MASTERDRIVES), which synchronise themselves with this
pulse.

Clock synchronous monomaster operation (DPM1)
The times for the setpoint transfer and actual value recording of the
slaves and the time of the control by the higher-level master can take
place through time parameters. The time parameters relate to the clock
pulse.
In the DP cycle there must be sufficient time for the following
communication elements:
♦
cyclical data exchange with all slaves on the bus
♦
a non-cyclical data channel (DPV1)
♦
telegram repeats
♦
diagnosis request
A local control device (PU, OP) at the DPM1 must communicate with the
slaves via the DPM1 master.
