Description
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 master/
local module and the device of the CPU module
is performed automatically.
The program accesses the link devices of the
master/local module directly.
A relay station transfers the link devices of the
master station and submaster station to another
network module.
This mode is selected for optimizing the
performance of cyclic transmission based on the
cyclic transmission and transient transmission
frequency.
The mode can be selected from "Online (Normal
Mode)" and "Online (High Speed Mode)".
The cyclic data integrity is assured in units of 32
bits or station-based units.
Link scan is set to asynchronous or
synchronous with the sequence scan of the
CPU module.
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 master/
local 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 master/local 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.
