Data stored Details
Total number of The total number of connected stations set in parameter is stored.
connected stations Range: 1 to 16
Reserved station The reserved station specification status of the slave station specified
specification status in parameter is stored. (0: Not specified, 1: Specified)
b0: Reserved station specification status
b1 to b15: Empty (fixed to 0)
The station number that is specified as a reserved station can be
checked in 'Reserved station specification status of each station'
(Un\G1026).
Reserved station The reserved station specification status is stored using the following
specification status of bit pattern. (Off: Other than the reserved station, On: Reserved station)

• Only the bit of the start station number turns on.
• The status is not stored for the station numbers after the maximum
station number.

Diagnostic information After the END instruction of the scan where the bit 0 is turned off and
display request on is executed, the diagnostic information of a slave station specified in
'Diagnostic request information' (Un\G1051) is read to Un\G1052 to
Un\G1077.
When reading of the diagnostic information has completed at END
processing, 0 is stored.
b0: Diagnostic information display request
