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). (Refer to Chapter 9.)
(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)
• When CPU RUN status (each station) (SB00F0) is turned on, check the
station number using CPU RUN status (each station) (SW00F0 to SW00F7).
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)
• When CPU operation status (each station) (2) (SB0110) is turned on, check
the station number using Operation status (each station) (2) (SW0110 to
SW0117).
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)
• When CPU operation status (each station) (1) (SB0100) is turned on, check
the station number using Operation status (each station) (1) (SW0100 to
SW0107).
Description
(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).
