• If the station number of the slave station that is specified in
'Diagnostic request information' (SD11127) is the start
station number of the occupied stations and the cyclic
transmission is performed for the slave station, 1 is stored
in b0 to b7 and b8 to b15. (If the specified slave station is a
reserved station, 0 is stored in b8 to b15.)
• If the station number of the slave station that is specified in
'Diagnostic request information' (SD11127) is other than the
start station number of the occupied stations or the cyclic
transmission is not performed for the slave station, 0 is
stored in b0 to b7 and b8 to b15.
• When b0 to b7 are valid, the number of occupied stations,
group number, IP address, the accumulated number of
timeouts, and the accumulated number of disconnection
detection are stored in 'Diagnostic request information 1'
(SD11129 to SD11140). When invalid, 0 is stored in
'Diagnostic request information 1' (SD11129 to SD11140).
• When b8 to b15 are valid, the Manufacturer code, Model

detailed module information are stored in 'Diagnostic
request information 2' (SD11144 to SD11153). When
invalid, 0 is stored in 'Diagnostic request information 2'
(SD11144 to SD11153).
When 1 (valid) is stored in b0 to b7 of SD11128, the number of
occupied stations, group number, IP address, the
accumulated number of timeouts, and the accumulated

'Diagnostic information display request' (SD11126) is turned
off and on is executed, the accumulated number of timeouts
that occurred in a slave station specified in 'Diagnostic
request information' (SD11127) is stored.
• 0: No timeouts
• 1 to 65535: Number of timeouts (accumulated number)
■SD11140: Accumulated number of disconnection detection
After the END instruction of the scan where the bit 0 of
'Diagnostic information display request' (SD11126) is turned
off and on is executed, the accumulated number of
disconnections that detected in a slave station specified in
'Diagnostic request information' (SD11127) is stored.
