Appendix 3.2
Data is stored in the link special registers SW000 to SW001F by the program, and data is automatically stored in
SW0020 to SW01FF.
The values in parentheses in the number column indicate the buffer memory addresses.
When a standby master station is used, refer to the respective columns under "Availability" in the table as explained
below.
• When a standby master station is operating as a master station: "Master station" column
• When a standby master station is operating as a standby master station: "Local station" column
Do not write data to the area of the No. which does not exist in the link special register (SW) list. Writing data to the area of
the No. which does not exist in the list may cause malfunction of the programmable controller system.
The following table lists the link special registers.

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.

Numbers 1 to 64 in the above table indicate the station numbers.
The stations need not be set by the number of occupied stations.
Error invalid stations, reserved stations and any station of the number higher than the
max. are not specified.
Set a station number where the loop test is executed.
0: Entire system (executed for all stations)
01 to 64: Specified station only
Default value: 0
Sets monitoring time when dedicated instructions are used.
Default: 10 (seconds) (value = 0)
Setting range: 1 to 360 (seconds)
If a value outside the range is set, the monitoring time will be 360 seconds.
When SW000B is set, the time until a dedicated instruction fails is as follows:
(Number of retries + 1) Monitoring time
Sets the monitoring time of CPU response when the CPU module is accessed
through transient transmission.
Default: 90 (seconds) (value = 0)
Setting range: 1 to 3600 (seconds)
If a value outside the range is set, the monitoring time will be 3600 seconds.
