(10)Checking CPU module status
The CPU module status is checked through the CC IE Control diagnostics, but it also can be checked with link
special relay (SB) and link special register (SW). ( Page 526, Section 10.3)
(a) Checking the CPU module status of other stations
1. Whether the CPU module is in RUN status or STOP status can be checked with the following link
special relay (SB) and link special register (SW).
• CPU RUN status of each station (SB00F0)
• CPU RUN status of each station (SW00F0)
2. When a continuation error occurs with the CPU module, CPU operation status of each station (2)
(SB0110) is turned ON.
The station No. of the station where a continuation error is occurring is stored in CPU operation
status of each station (2) (SW0110).
3. When a stop error occurs with the CPU module, CPU operation status of each station (1) (SB0100)
is turned ON.
The station No. of the station where a stop error is occurring is stored in CPU operation status of
each station (1) (SW0100).
(b) Checking CPU module status of own station
1. Whether the CPU module is in RUN status or STOP status can be checked with Own station's CPU
RUN status (SB005B).
2. When a continuation error occurs with the CPU module, Own station's CPU status (1) (SB004A) is
turned ON.
When a stop error occurs with the CPU module, Own station's CPU status (2) (SB004B) is turned
ON.
3. The CPU module status can be checked with Own station's CPU status (SW004B).
