I/O Signals for the Programmable Controller CPU Detailed Description of the Module
MELSEC-L Series – CANopen Module ME3CAN1-L 3 – 9
ME3CAN1-L error (XnF), ME3CAN1-L error clear request (YnF)
●
If one or more of the following bits in the buffer memory address Un\G29 (error state) are turned
ON, XnF will be turned ON: Bits 1, 2, 4, 5, 6, 8, or 15. Please refer to section 3.5.7.
●
If XnF is turned ON, if necessary please take corrective action to remove the error cause and then
turn ON YnF to clear the error signals XnF and the bits in the error state (Un\G29).
●
If a new error is generated while the ME3CAN1-L error clear request (YnF) is ON, this will be cleared
automatically.
●
After the ME3CAN1-L error clear request (YnF) is turned OFF, the ME3CAN1-L will check for new
errors again.
NMT Error Control failure available (X(n+1)0), NMT Error Control failure clear request (Y(n+1)0)
●
If there is at least one CANopen NMT Error Control failure (at least one of the assigned NMT slaves
failed during NMT Error Control), the NMT error of CANopen node available (X(n+1)0) will turn
ON.
●
How to clear the error of all nodes
To clear the error of all nodes, write 0000
H
to Un\G400 (this is the default setting of Un\G400) and
turn ON the Clear NMT Error Control failure request (Y(n+1)0). The NMT error control failures of
all nodes will be then cleared and the NMT Error Control failure available (X(n+1)0) will be turned
OFF.
●
How to clear the error of a certain node
To clear the error of a node, write the node number to Un\G400 and turn ON NMT Error Control
failure clear request (Y(n+1)0). The NMT error control failures of this node will be cleared and if
there no other NMT error control failures the NMT Error Control failure available (X(n+1)0) will also
be turned OFF.
●
If a new error is generated while the NMT Error Control failure clear request (Y(n+1)0) is ON, this
will be cleared automatically.
●
After the NMT Error Control failure Clear request (Y(n+1)0) is turned OFF, the ME3CAN1-L will
check for new errors again.
●
For more error details on NMT Error Control failure, please refer to section 3.5.15.
