The bit corresponding to the station number which is in
STOP or PAUSE mode, becomes "1".
Example: When local stations 7 and 15 are in STOP mode,
bits 6 and 14 of SD1248 become "1", and when
SD1248 is monitored, its value is "16448
(4040

Fuse blown
module
Bit pattern in units
of 16 points,
indicating the
modules whose
fuses have blown
0: No blown fuse
1: Blown fuse
present
• The numbers of output modules whose fuses have blown are
input as a bit pattern (in units of 16 points).
(If the module numbers are set by parameter, the parameter-set
numbers are stored.)
• Also detects blown fuse condition at remote station output
modules
