"F" in the above table indicates a forward loop line, and "R" a reverse
loop line. The bit of the device number corresponding to the station
number of the local station or remote I/O station that has a forward
loop line or reverse loop line error.
Example: When the forward loop line of station 5 has an error, b8 of
SD1232 become "1", and when SD1232 is monitored, its
value is "256 (100 )".
H
Stores the number of times the following transmission errors have
been detected:
CRC, OVER, AB. IF
Count is made to a maximum of FFFF .
H
To return the value to "0", perform reset operation.
Stores whether the slave station corresponds to MELSECNET or
MELSECNET II.
• Bits corresponding to the MELSECNET II stations become "1."
• Bits corresponding to the MELSECNET stations or unconnected
become "0."

• If a local station goes down during the operation, the contents
before going down are retained.
Contents of SD1224 to SD1227 and SD1228 to SD1231 are ORed.
If the corresponding bit is "0", the corresponding bit of the special
register above becomes valid.
• If the host (master) station goes down, the contents before going
down are also retained.
Allows a local station to confirm its own station number
Indicates the number of slave stations in one loop.
Stores the number of times the following transmission errors have
been detected: CRC, OVER, AB. IF
Count is made to a maximum of FFFF . To return the value to "0",
H
perform reset operation.
