Description
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication timeout.
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 reception of 2K bytes or more at the
reverse loop (OUT-side).
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 reverse loop (OUT-side)
communication DPLL 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 occurrence count of the forward loop (IN-side) communication retry.
0: No error
1 or greater: Cumulative count
Values may be counted up at power-on or reset, but it is not an error. If the retry count is
unnecessary before data link starts, clear the value using 'Clear retry count' (SB0005).
Stores the cumulative occurrence count of the reverse loop (OUT-side) communication
retry.
0: No error
1 or greater: Cumulative count
Values may be counted up at power-on or reset, but it is not an error. If the retry count is
unnecessary before data link starts, clear the value using 'Clear retry count' (SB0005).
Stores the cumulative occurrence count of the forward loop (IN-side) line error detection
(hardware error detection).
0: No error
1 or greater: Cumulative count
Stores the cumulative occurrence count of the reverse loop (OUT-side) line error
detection (hardware error detection).
0: No error
1 or greater: Cumulative count
Stores the cumulative occurrence count of the loop switch.
0: No count
1 or greater: When 'Clear reverse loop transmission error count' (SB0009) is turned on,
the cumulative count is cleared.
Stores a pointer storing the latest loop switch status in 'Loop switch data' (1) (SW00D0 to
SW00DF).
0: The latest loop switch status is stored in SW00D0.
1: The latest loop switch status is stored in SW00D1.
2: The latest loop switch status is stored in SW00D2.
3: The latest loop switch status is stored in SW00D3.
4: The latest loop switch status is stored in SW00D4.
5: The latest loop switch status is stored in SW00D5.
6: The latest loop switch status is stored in SW00D6.
7: The latest loop switch status is stored in SW00D7.
8: The latest loop switch status is stored in SW00D8.
9: The latest loop switch status is stored in SW00D9.
10: The latest loop switch status is stored in SW00DA.
11: The latest loop switch status is stored in SW00DB.
12: The latest loop switch status is stored in SW00DC.
13: The latest loop switch status is stored in SW00DD.
14: The latest loop switch status is stored in SW00DE.
15: The latest loop switch status is stored in SW00DF.
