(10)Checking CPU module status
The CPU module status is checked using the CC-Link IE Field Network diagnostics as well as link special relays
(SBs) and link special registers (SWs). (
(a) Checking the CPU module status (other stations)
1.
Whether the CPU module is in RUN or STOP can be checked using the following link special relays
(SBs) and link special registers (SWs).
• CPU RUN status (master station) (SB00F1)
• CPU RUN status (station No.0) (SB00FF)
• When CPU RUN status (each station) (SB00F0) is turned on, check the station number using CPU RUN
status (each station) (SW00F0).
2.
A continuation error in the CPU module can be checked using the following link special relays
(SBs) and link special registers (SWs).
• CPU operation status (master station) (2) (SB0111)
• CPU operation status (2) (station No.0) (SB011F)
• When CPU operation status (each station) (2) (SB0110) is turned on, check the station number using
Operation status (each station) (2) (SW0110).
3.
A stop error in the CPU module can be checked using the following link special relays (SBs) and
link special registers (SWs).
• CPU operation status (master station) (1) (SB0101)
• CPU operation status (1) (station No.0) (SB010F)
• When CPU operation status (each station) (1) (SB0100) is turned on, check the station number using
Operation status (each station) (1) (SW0100).

(b) Checking CPU module status (own station)
1.
Whether the CPU module is in RUN or STOP can be checked using CPU RUN status (own station)
(SB004C).
2.
If a continuation error occurs in the CPU module, Own station's CPU status (1) (SB004A) turns on.
If a stop error occurs in the CPU module, Own station's CPU status (2) (SB004B) turns on.
3.
The CPU module status can be checked using Own station's CPU status (SW004B).
