Description
Stores the information about operating status of the CC-Link IE TSN Network
synchronous communication function for each station.
0: Asynchronous setting
1: Synchronous setting
Stations which are not executing an inter-module synchronous interrupt program
because the CPU operating status is currently STOP or PAUSE (the status under
which the program cannot be executed) are also treated as asynchronous setting (0).

SW01CF
Each number in the table represents a station number.
 is fixed to 0.
(Conditions)
• Stations that surpass the maximum station number are ignored.
Stores the watchdog counter operating status information for each station in CC-Link
IE TSN network communications.
0: Not operating
1: Operating
Stations that are not performing data links are treated as "0: Not operating" because
the information indicates that the slave station in communication is equipped with a
watchdog counter.

SW01D7
Each number in the table represents a station number.
 is fixed to 0.
(Conditions)
• Stations that surpass the maximum station number are ignored.
Indicates the number of times cyclic data transfer processing is not completed within
the inter-module synchronization cycle. The status is cleared by powering off and on
the system or by resetting the CPU module.
0: Cycle over not occurred
1 to 65535: Cumulative number of times
When FFFFH (maximum value 65535) is counted, counting stops.
Stores the cycle setting value of the fixed interval synchronization of Inter-module
synchronization. (Unit: s)
0 is stored when the inter-module synchronization function is not used.
Stores the request result of 'Remote device forced output request' (SB0016).
0: Normal
1 or greater: Not completed
If not completed, an error code is stored.
When 'Remote device forced output request' (SB0016) is turned off, the stored error
code is cleared.
