Diagnostic information 1 When 1 (valid) is stored in b0 to b7 of Un\G1052, the number of
occupied stations, group number, IP address, the accumulated number
of timeouts, and the accumulated number of disconnection detection
are stored. When 0 (invalid) is stored in b0 to b7 of Un\G1052, 0 is
stored.
■Un\G1053: Number of occupied stations
■Un\G1054: Group number
■Un\G1055: IP address (lower)
■Un\G1056: IP address (upper)
1 to 4: First octet to fourth octet
When the IP address has not been set in the parameter, 0 is stored.
■Un\G1063: Accumulated number of timeouts
After the END instruction of the scan where the bit 0 of 'Diagnostic
information display request' (Un\G1050) is turned off and on is
executed, the accumulated number of timeouts that occurred in a slave
station specified in 'Diagnostic request information' (Un\G1051) is
stored.
• 0: No timeouts
• 1 to 65535: Number of timeouts (accumulated number)
*2
■Un\G1064: Accumulated number of disconnection detection
After the END instruction of the scan where the bit 0 of 'Diagnostic
information display request' (Un\G1050) is turned off and on is
executed, the accumulated number of disconnections that detected in
a slave station specified in 'Diagnostic request information' (Un\G1051)
is stored.
• 0: No disconnections
• 1 to 65535: Number of disconnection detection (accumulated
number)

module information, error code, and detailed module information are
stored. When Diagnostic information 2 is invalid (0 is stored in b8 to
b15 of Un\G1052), 0 is stored.
