: For a multiple PLC system, the slot number or PLC number is
stored depending on the error that occurred.
Slot 0 in the multiple PLC system is the one on the slot on the
right of the rightmost CPU.
(Refer to the corresponding error code for which number has
been stored.)
PLC No. 1: 1, PLC No. 2: 2, PLC No. 3: 3, PLC No. 4: 4
2
: If a fuse blown or I/O verify error occurred in the module loaded
in the MELSECNET/H remote I/O station, the network number
is stored into the upper 8 bits and the station number into the
lower 8 bits.
Use the I/O No. to check the module where the fuse blown or
I/O verify error occurred.
