Data is stored in the link special registers SW000 to SW003F by the sequence
program, and data is automatically stored in SW0040 to SW01FF. The values in
parentheses in the number column indicate the buffer memory addresses.
When the standby master station is controlling the data link, availability is basically
identical to that of the master station.
When the standby master station is operating as a local station, availability is identical
to that of a local station.
Table 8.4 Link special register list (1/7)
Select whether multiple temporary error invalid stations are specified.
00 : Specifies multiple stations indicated by SW0004 to
SW0007.
01 to 64: Specifies a single station from 1 to 64.
(The specified number indicates the station number of a
temporary error invalid station.)
Specifies a temporary error invalid station.
0: Not specified as a temporary error invalid station
1: Specified as a temporary error invalid station

Default value: 0
Sets the monitoring time when a dedicated instruction is used.
Default value: 10 (seconds)
Setting range: 0 to 360 (seconds)
The monitoring time of 360 seconds will be used if a value outside
of the above setting range is specified.
Sets the CPU response monitoring time when the CPU is accessed
with a dedicated instruction.
Default value: 90 (seconds)
Setting range: 0 to 3600 (seconds)
The monitoring time of 3600 seconds will be used if a value outside
of the above setting range is specified.
Indicates the module status.
0 : Normal
Other than 0: Stores the error code (see Section 13.3).
Stores the execution result of the data link restart instruction with
SB0000.
0 : Normal
Other than 0: Stores the error code (see Section 13.3).
Indicates the execution result of refresh instruction at standby master
switching.
0 : Normal
Other than 0: Stores the error code (see Section 13.3).
