FX2N-16CCL-M CC-Link System Master Block Overview 2

6) Parameter registration to the EEPROM
By registering the parameters to the EEPROM in advance, the parameter settings do not
have to be executed at each startup (power OFF
→
ON) of the master station.
The data stored in the EEPROM remains stored even if the power of the module is turned
off.
7) Data link status setting for a case where an error occurs in the CPU in the master station (PLC)
The data link status can be set (to "stop" or "continue") for a case where an "operation stop
error" such as a PLC program error occurs in the master station.
When an "operation continue error" such as a battery error occurs, the data link continues
without regard to the setting.
8) Status setting of the input data from a data link faulty station
The data input (received) from a data link faulty station can be cleared or kept (in the status
right before an error occurs).
9) Module reset function from a sequence program
When the switch setting is changed or an error occurs in the module, the module can be
reset from a sequence program without resetting the PLC.
(This excludes when the module has a module faulty input (BFM No. A
H
b0 is ON)).
10)RAS function
a) Automatic return function
When a station was disconnected from the link due to power OFF, etc. then returns to
normal status, the station can join the data link again automatically.
b) Link status check
Using the link special relay (SB) and the link special register (SW) in the buffer memory,
the current data link status can be checked.
c) Diagnosis function
Using the switch setting, the hardware and the cable wiring can be checked.
