4.1 Function List
Description
Communicates I/O data in units of bits between the master station
and other stations.
Communicates I/O data in units of words between the master station
and other stations.
The mode can be selected according to the CC-Link system
configuration.
Automatically transfers data between the link device of the master/
intelligent device module and the device of the CPU module.
Prevents the link refreshed read/write data from being separated
between new and old data.
When Selects whether remote input (RX) from a station
operating where a data link error occurs is cleared or held.
as a master
station
When Selects whether output data (RY/RWw) from the
operating master station is cleared or held.
as an
intelligent
device
station
When Selects whether remote output (RY) is refreshed (held
operating at the value before STOP) or cleared to zero (0) when
as a master the CPU module is set to STOP.
station
When Selects whether input data to the master station (RX/
operating RWr) is refreshed (held at the value before STOP) or
as an cleared to zero (0) when the CPU module is set to
intelligent STOP.
device
station
Selects whether data link is stopped or continued when a stop error
occurs in the CPU module.
When Selects whether remote output (RY) to the slave
operating station is held or cleared when a stop error occurs in
as a master the CPU module.
station
When Selects whether remote input (RX/RWr) to the master
operating station is held or cleared when a stop error occurs in
as an the CPU module.
intelligent
device
station
Stops data link during debugging and other operations. (Data
sending from the own station is stopped.) Also, the stopped data link
is restarted.
