RJ71CN91 error (XF), RJ71CN91 error clear request (YF)
'RJ71CN91 error' (XF) turns on if either bit 1, 3, 4, 5, 6, 8, or 15 of 'Error status' (Un\G29) turns on. ( Page 161 Error
status (Un\G29))
When 'RJ71CN91 error' (XF) turns on, remove the error cause as necessary and then turn on 'RJ71CN91 error clear request'
(YF). Turning on 'RJ71CN91 error clear request' (YF) clears each bit in 'Error status' (Un\G29) and turns off 'RJ71CN91 error'
(XF).
While 'RJ71CN91 error clear request' (YF) is turned on, an error other than a major error cannot be detected.
And, as long as a major error does not occur, any bit of 'Error status' (Un\G29) and 'RJ71CN91 error' (XF) do not turn on.
When 'RJ71CN91 error clear request' (YF) is turned off, error detection resumes.
All the bits of 'Error status' (Un\G29) automatically turn off when the error cause is removed. They are also turned off while
'RJ71CN91 error' (XF) is turned on, but if the error cause is not removed, they will be turned on again when 'RJ71CN91 error'
(XF) is turned off.

• When 'RJ71CN91 error clear request' (YF) is turned on, the ERR LED turns off, and the error information in
the Module Diagnostics window is deleted. (Excluding when a major error occurs)
• While 'RJ71CN91 error clear request' (YF) is turned on, the ERR LED neither turns on nor flashes. And,
error information is not displayed in the Module Diagnostics window or the event history. (Excluding when a
major error occurs)
• The targets to be cleared by 'RJ71CN91 error clear request' (YF) also include an NMT error control failure.
NMT error control failure available (X10), NMT error control failure clear request (Y10)
When NMT error control failed (NMT error control failed in an NMT slave of the RJ71CN91), 'NMT error control failure
available' (X10) turns on.
To clear errors of all CANopen nodes, write 0000H (initial value) in 'NMT error clear node' (Un\G400), and turn on 'NMT error
control failure clear request' (Y10). NMT error control failure is cleared in all CANopen nodes, and 'NMT error control failure
available' (X10) turns off.
To clear errors of a specific CANopen node, write the node ID of the target node in 'NMT error clear node (Un\G400), and turn
on 'NMT error control failure clear request' (Y10). NMT error control failure is cleared in the target node, and if there is no
other errors, 'NMT error control failure available' (X10) turns off.
While 'NMT error control failure clear request' (Y10) is turned on, an NMT error control failure in the target CANopen node is
not detected.
Also, when no NMT error control failure occurs in other CANopen nodes, 'NMT error control failure available' (X10) does not
turn on.
When 'NMT error control failure clear request' (Y10) is turned off, the detection of an NMT error control failure in the target
CANopen node resumes.
For details on NMT error control failure, refer to the following.
Page 168 NMT error control status (Un\G401 to Un\G527)
While 'NMT error control failure clear request' (Y10) is turned on, even if an NMT error control failure occurs in
the target CANopen node, it is not displayed in the event history.
