FUNCTION LIST
This chapter describes the functions can be used in the master station on CC-Link IE Field Network Basic.
Some functions have restrictions on versions of the CPU module of each series or GX Works3/CW
Configurator/GX Works2.

Description
Periodically performs data communication between the master station and slave
stations using link devices (RX/RY/RWr/RWw). ( Page 22 Data flow and link
device assignment)
Automatically transfers data between devices and link devices of the master
station. ( Page 26 Link refresh)
Assures cyclic data integrity in station-based units.
Divides slave stations into groups by setting a group number to each slave
station and each of groups performs the cyclic transmission. By organizing
groups separating slave stations with shorter response processing time from
ones with longer response processing time, the differences of the reference
response times of each slave station does not badly affect the cyclic
transmission. ( Page 30 Group number setting)
Clears or holds status of input from a data link faulty station and output status of
cyclic data if a stop error occurs in the CPU module ( Page 32 Input and
output status when failure occurs)
Clears or holds cyclic data output when the CPU module is set to STOP state.
( Page 32 Output status for CPU STOP)
Description
Disconnects the corresponding slave station if no response is received within the
timeout time or number of times for disconnection detection set in the slave
station disconnection detection settings. ( Page 39 Link Scan Setting)
Automatically returns a disconnected station to the network and restarts the data
link when the station returns to normal.
Description
Checks the status of CC-Link IE Field Network Basic. ( Page 43 CC-Link IE
Field Network Basic Diagnostics)
Description
Reserves a station (a station not actually connected but counted as a connected
station) for future use. A reserved station is not detected as a faulty station even
though it is not actually connected. ( Page 33 Reserved Station
