Fig. 4-14 SIMOLINK telegram data transfer
Telegram runtime: s 366.
All of the telegrams are sent immediately one after the other.
For instance, for a selected bus cycle time of 0.6 ms, the SL master
can transfer
– one double word each to a max. of 91 slaves/transceiver, or
– 4 double words each to a max. of 22 slaves/transceiver
The remaining times are intervals where a telegram is not sent (NOP).
Master-slave process data transfer:
– up to 200 slaves/transceiver can be addressed with address gaps
– up to 8 double words individually for each slave/transceiver
– own process data for each slave/transceiver
Dispatcher transceiver process data transfer:
– up to 200 consecutively addressed transceivers
– up to 8 double words
– the same number of used channels for dispatcher and transceiver
(nodes with a max. number of double words defines the number
of channels for all)
Data transfer rate: 11 Mbit/s
Bus topology: Fiber-optic cable ring, each node as
signal amplifier
Max. distance between two nodes:
40 m for plastic fiber-optic cables, or
300 m for glass fiber-optic cables.
