The slave device is communicated in the fixed cycle. The communication
cycle is the same as an operation cycle of the Simple Motion module.
The processing cycles of the Simple Motion module and each slave station
are synchronized.
The master station communicates I/O data in units of bits with other stations.
The master station communicates I/O data in units of words with other
stations.
Transfer between the link device of the Simple Motion module and the device
of the CPU module mounted with a Simple Motion module is performed
automatically.
The program accesses the link devices (RX, RY, RWr, RWw, SB or SW) of
the Simple Motion module directly.
The cyclic data integrity is assured in units of 32 bits or station-based units.
Whether input data from another station where a data link error occurs is
cleared or held is selected.
When the CPU module mounted with a Simple Motion module is set to
STOP, whether cyclic data output is held or cleared can be selected.
When a stop error occurs in the CPU module where a Simple Motion module
is mounted, whether cyclic transmission output is held or cleared can be
selected.
During debugging and other operations, cyclic transmission is stopped. (Data
reception from a slave station and data sending from the own station are
stopped.) Also, the stopped cyclic transmission is restarted.
Transient transmission does not stop.
