11 PC150 NMI SLC aa cc A communication error occurred in the I/O link.
aa, cc: I/O link error information (Make a written record of this information; it will
be required when an investigation is made by FANUC.)
Possible causes of this error are as follows:
(1) When I/O Unit A is used, bases 1, 2, and 3 are not connected even though
bases 1, 2, and 3 are assigned.
(2) Poor cable connection
(3) There is a defective cable.
(4) Input/output equipment (such as an I/O unit or Power Mate) is faulty.
(5) The PMC board (printed circuit board in the host to which the I/O Link cable
is connected) is faulty.
Solution)
Check the cause of the error.
(1) On the screen brought up by clicking EDIT → MODULE, check the assign-
ment data, and compare it with the actual connection status.
(2) Check whether the cables are connected correctly.
If checks 1 and 2 above reveal no problem, the hardware may be faulty. De-
termine the location of the fault by following the steps explained below.
(3) Refer to “FANUC I/O Unit−MODEL A Connection and Maintenance Manual”
(B−61813E) or the “FANUC I/O Unit−MODEL B Connection Manual”
(B−62163E), and check whether the cables satisfy the specifications.
(4) Replace the interface module, cable, and PMC board of the I/O unit one by
one and, at each step, check whether the error still occurs.
If the error still occurs after all the units related to the I/O Link are replaced
in 4 above, the communication error may have been caused by noise. Deter-
mine the cause of the noise.

Message Contents and solution
ADDRESS BIT NOTHING The address of the relay/coil is not set.
FUNCTION NOT FOUND There is no functional instruction of the input number.
COM FUNCTION MISSING The funcitonal instruction COM (SUB29) is not correctly dealt with.
Correspondence of COM and COME (SUB29) is incorrect.
Or, the number of coil controlled by COM is specified by the model which the number
cannot be specified.
EDIT BUFFER OVER There in no empty area of the buffer for the editing.
(solution) Please reduce NET under editing.
END FUNCTION MISSING Functional instruction END1,END2,END3 and END do not exist. Or, there are error net
in END1,END2,END3,END.
Or, order of END1,END2,END3, and END is not correct.
