AD error status is shown in the table below
D8403 (AD
sampling error)
ON state
OFF state
Bit 0
There is an error, and any non-zero A/D
conversion of Bit 0~Bit 3 will stop
No error
Bit 1
Wrong offset/gain setting
Offset/gain correct
Bit 3
Hardware malfunction
Hardware is normal
Bit 4
Number is outside the range of -2048 to 2047
Digital output is normal
Bit 5
Sampling filter constant exceeds the range of
1 to 4096
Sampling filter constant
is normal
Bit 15
AD parameter initialization is unsuccessful,
need to set M8420 to reinitialize
AD parameter
initialization is normal
DA error status is shown in the table below
