ALARM LISTMessagePC150 NMI SLC aa ccSTATUS LED PC160 F–BUS ERROR xxxx yyyyyySTATUS LED PC199 ROM PARITY eeeeeeeeSTATUS LED Contents and solutionThe communication error occurred in the I/O Link.aa, cc : I/O Link error information. Note 2)This error may occur by the following causes.1. When I/O Unit–MODEL A is used, base1, 2 or 3 is not connected though allocated.2. The connection of cable is insufficient.3. Defects of cable.4. Defects of DI/DO units (I/O unit, Power Mate etc.)5. Defects of PMC board (printed circuit board on host side where I/O Link cable is connected.)(solution) Investigate the cause of error.1. Please confirm the allocation data (by ”EDIT”→”MODULE” screen) and comparewith the actual connection.2. Please confirm whether the cable is correctly connected.If you cannot find the causewith the ways above, it may be the defect of hardware.Please investigate a defective place by the following methods.3. Please confirm the specification of the cable referring to”FANUC I/O Unit–MODELA CONNECTION MAINTENANCE MANUAL (B–61813E)” or ”FANUC I/O Unit–MODEL B CONNECTION MANUAL (B–62163E)”.4. Exchange the interface module of I/O Unit, the cable and the PMC board, etc. oneby one and, confirm whether this error occurs again.The communication may fail bythe noise etc. when this error still occurs after replacing all DI/DO units.Please investigate the cause of noise.The BUS error (access to disabled address) occurred.xxxx : Segment selector where system error occurred.yyyyyy : Offset address where system error occurredThe parity error occur in PMC system ROM.eeeeeeee : ROM parity error information.STATUS LED (green) are LED1, LED2 on PMC–RC. CAP–II is LED3 and LED4. : Off, : On, : BlinkingNOTE1 The system error on PMC–RA1, RA2, RA3, RB,RB2 and RB3 is displayed as a system erroron the CNC side. (Refer to the “FANUC Series 16/18/160/180–MC Operator’s Manual(B–62764EN)” or “FANUC Series 16/18/160/180–TC Operator’s Manual (B–62754EN)”.)2 Error information is needed to investigate on FANUC, please take notes of it.(2) Alarm messages (For EDIT 1)MessageContents and solutionADDRESS BIT NOTHINGFUNCTION NOT FOUNDCOM FUNCTION MISSINGEDIT BUFFER OVEREND FUNCTION MISSINGERROR NET FOUNDThe address of the relay/coil is not set.There is no functional instruction of the input number.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 numbercannot be specified.There in no empty area of the buffer for the editing.(solution) Please reduce NET under editing.Functional instruction END1,END2,END3 and END do not exist.
