Low-speed cyclic
transmission start
execution results
Stores execution results for low-speed cyclic transmission start
execution results.
0 : Test normal
Other than 0
: Test error content (refer to the error codes in
Section 8.3)
2: Valid only when SB0047 is off. When it turns on (error), the last data are retained.
7: To reset the SW00CE to SW00E7, turn on the SB0009.
8: For the loop switch request station, stations other than the ones at both ends of the loop may be stored because the loop switch request is issued by the
station that first detected the loop error.
