(191)
DPLL error on the forward
loop side/coaxial bus
DPLL error
Accumulates and stores the number of "DPLL" errors on the
forward loop side for the optical loop, or the number of "DPLL"
errors of the coaxial bus for the coaxial bus.
Other than 0: Number of errors
3
SW00C0
(192)
UNDER on the reverse
loop side
Accumulates and stores the number of "UNDER" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C1
(193)
CRC on the reverse loop
side
Accumulates and stores the number of "CRC" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C2
(194)
OVER on the reverse
loop side
Accumulates and stores the number of "OVER" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C3
(195)
Short frame on the
reverse loop side
Accumulates and stores the number of "Short frame" errors on
the reverse loop side.
Other than 0: Number of errors
3
SW00C4
(196)
Abort on the reverse loop
side (AB, IF)
Accumulates and stores the number of "AB.IF" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C5
(197)
Timeout on the reverse
loop side (TIME)
Accumulates and stores the number of "TIME" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C6
(198)
Receiving 2k bytes or
more on reverse loop side
(DATA)
Accumulates and stores the number of "DATA" errors on the
reverse loop side.
Other than 0: Number of errors
3
SW00C7
(199)
DPLL error on reverse
loop side
Accumulates and stores the number of "DPLL" errors on the
reverse loop side.
Other than 0: Number of errors
4
SW00C8
(200)
Number of retries on the
forward loop side/ coaxial
bus retries error
Accumulates and stores the number of retries on the forward
loop side for the optical loop, or the number of retries of the
coaxial bus for the coaxial bus.
Other than 0: Number of errors
4
SW00C9
(201)
Number of retries on the
reverse loop side
Accumulates and stores the number of retries on the reverse
loop side.
Other than 0: Number of errors
5
SW00CC
(204)
Line error on the forward
loop side
Accumulates and stores the number of detected line errors on
the forward loop side.
Other than 0: Number of detected line errors
6
SW00CD
(205)
Line error on the reverse
loop side
Accumulates and stores the number of detected line errors on
the reverse loop side.
Other than 0: Number of detected line errors
7
SW00CE
(206)
Number of loop switches
Accumulates and stores the number of loop checks conducted.
Other than 0: Number of loop switches
7
SW00CF
(207)
Loop switch data pointer Stores the pointer that indicates the next loop switch data.
3: To reset from the SW00B8 to C7, turn on the SB0006.
The numbers of times stored in the SW00B8 to SW00C7 will not cause any problems if they are counting up gradually over a long period of time. If they are
counted up rapidly in a short period of time (while monitoring with GX Developer, etc.), the cable may be faulty.
4: This may be counted up at power on/reset, but it is not an error.
Clear with the SB0005 when the number of retries is not required before starting data linking.
5: To reset the SW00CC, turn on the SB0007.
6: To reset the SW00CD, turn on the SB0008.
7: To reset the SW00CE to SW00E7, turn on the SB0009.
