The reserved station specification status is stored using the following
bit pattern. (Off: Other than the reserved station, On: Reserved station)
The numbers in the figure indicate station numbers.
(Condition)
• 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
display request
After the END instruction of the scan where the bit 0 is turned off and
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.
