5. Functions
This chapter describes the functions of the CC-Link master block for the FX Series.
5.1 Function List
Table 5.1:
Item Function summary Reference
Communication between
master station and remote
I/O stations
Transfers the ON/OFF information with remote I/O stations.
5.2
Communication between
master station and remote
device stations
Transfers the ON/OFF information and the numeric data with
remote device stations.
5.3
Communication in
compound system Transfers data with remote I/O stations and remote device
stations.
5.4
Reserved station function
Sets remote stations to be connected in the future as reserved
ones so that such stations are not handled as data link faulty
stations.
If a connected station is set as a reserved one, data link is
disabled in the station.
5.5
Error invalid station function
Sets remote stations as "error invalid" so that such stations are
not handled as data link faulty stations.
5.6
Data link status setting
against error in master
station PLC CPU
Sets the data link status for a case in which an operation stop
error occurs in the master station PLC.
5.7
Parameter registration to
EEPROM
Registers the parameters to the EEPROM built in the master
module so that the parameters do not have to be written every
time the master module starts up.
7.1.1
Setting of input data status
from data link faulty station Sets the status (clear or keep) of the data input (received) from
a station in which data link fails due to power OFF, etc.
5.8
Module reset function from
sequence program
Resets a module from a sequence program without resetting
the PLC when the switch settings are changed or an error
occurs in the module.
5.9
Data link stop/restart
Stops and restarts the data link while the data link is executed
by the write request for data link startup by buffer memory
parameters (BFM#A
H
b6) or the write request for data link
startup by EEPROM parameters (BFM#A
H
b8).
5.10
RAS
function
Automatic return
function
Allows a module which was disconnected from the data link by
power OFF, etc. to automatically join the data link again when it
recovers normal status.
5.11.1
Slave station
cutoff function
Cuts off only modules in which data link is disabled by power
OFF, etc., and continues the data link using only normal
modules.
5.11.2
Data link status
check (SB/SW) Allows to check the data link status.
This function is useful to interlock in a sequence program, etc.
9.3
Offline test
Executes the following tests:
• Hardware test: Checks operations in a single module.
• Line test: Checks the connection status of modules.
• Parameter verification test: Verifies the contents of the
preset parameters.
