Description
Shows the items of the offline test at the response side.
3: Loop test (Forward loop)
4: Loop test (Reverse loop)
(Conditions)
• This register is enabled when 'Offline test response completion (issuance at another
station)' (SB00AF) is on.
Stores the results of the offline test at the response side.
0: Completed normally
1 or greater: Completed with an error (An error code is stored.)
(Conditions)
• This register is enabled when 'Offline test response completion (issuance at another
station)' (SB00AF) is on.
Stores the forward loop (IN-side) use status of each station during multiplex transmission.
Off: Other than forward loop (IN-side)
On: Forward loop (IN-side) used

Each number in the table represents a station number.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Reserved stations and stations with a number equal to or greater than the maximum
station number are ignored.
Stores the reverse loop (OUT-side) use status of each station during multiplex
transmission.
Off: Other than reverse loop (OUT-side)
On: Reverse loop (OUT-side) used

Each number in the table represents a station number.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Reserved stations and stations with a number equal to or greater than the maximum
station number are ignored.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
under-error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
CRC error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
overrun error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
