FX2N-16CCL-M CC-Link System Master Block
a) Number of connected modules
Set the number of remote station modules (including reserved stations) connected to the
master station.
This is not a station count.
The setting range is "1 to 15 (modules)".
Point
The station information (address 20
modules" becomes valid.
b) Number of retries
Set the number of retries to a remote station with a link data error.
The setting range is "1 to 7 (times)".
If a remote station cannot recover the normal data link after executing the specified
number of retries, the station is regarded as a "data link faulty station".
c) Number of automatic return modules
Set the number of remote station modules that can return to the system during one link
scan.
The setting range is "1 to 10 (modules)".
d) Operation specification for CPU shut down
Specify the data link status when an "operation stop error" occurs in the master station
PLC.
The setting range is "0 (stop)" and "1 (continue)".
e) Reserved station specification
Set remote stations which are included in the number of connected modules but are not
actually connected now so that such stations will not be handled as "data link faulty
stations"
1) When a connected remote station is set as a reserved station, the station cannot
execute any data link at all.
2) Set to ON the bits corresponding to the station numbers to be set as reserved.
For a remote station which occupies 2 or more stations, turn on only the bit for the
station Number set by the module's station number setting switch.
Numbers 1 to 15 indicate the station numbers in the table below.
