CHAPTER12 PECIAL RELAY LIST AND SPECIAL REGISTER LIST
Details
• When fuse blown modules are detected, the first I/O number of the
lowest number of the detected modules is stored in hexadecimal.
(Example: When fuses of Y50 to 6F output modules have blown,
"50" is stored in hexadecimal)
To monitor the number by peripheral devices, perform monitor
operation given in hexadecimal.
(Cleared when all contents of SD1100 to SD1107 are reset to 0.)
• Fuse blow check is executed also to the output modules of remote
I/O stations.
• Stores the module numbers corresponding to setting switch
numbers or base slot numbers when fuse blow occurred.

• For the remote I/O station, the value of (module I/O No./10H) + 1 is
stored.
• If I/O modules, of which data are different from data entered, are
detected when the power is turned on, the first I/O number of the
lowest number unit among the detected units is stored in
hexadecimal. (Storing method is the same as that of SD1000.)
To monitor the number by peripheral devices, perform monitor
operation given in hexadecimal.
(Cleared when all contents of SD1116 to SD1123 are reset to 0.)
• I/O module verify check is executed also to the modules of remote
I/O terminals.
• When the AC power supply module is used, 1 is added at
occurrence of an instantaneous power failure of within 20ms.
(The value is stored in BIN code.) It is reset when the power supply
is switched from OFF to ON.
• When the DC power supply module is used, 1 is added at
occurrence of an instantaneous power failure of within 10ms.
(The value is stored in BIN code.) It is reset when the power supply
is switched from OFF to ON.
• When error is found as a result of self-diagnosis, error number is
stored in BIN code.
