Conversion setting for disconnection detection
Conversion setting for disconnection detection (address: 010FH) can configure the values stored in CH Digital output value
(RWr2 to RWr5) and CH Digital output value (32 bits) (RWr10 to RWr17) upon disconnection detection. Thus, disconnection
detection is enabled only by checking CH Digital output value (RWr2 to RWr5) and CH Digital output value (32 bits)
(RWr10 to RWr17) without monitoring Disconnection detection signal (RX1B). The default value of Conversion setting for
disconnection detection (address: 010FH) is Down scale (1H). Change the setting value as needed.
Conversion setting for disconnection detection
Up scale (0H)
Down scale (1H)
Arbitrary value (2H)
Value immediately before disconnection (3H)
■Up scale and down scale
The up-scale value (upper limit value + 5% of the input range) and down-scale value (lower limit value - 5% of the input range)
of the input range currently set are stored in CH Digital output value (RWr2 to RWr5) and CH Digital output value (32 bits)
(RWr10 to RWr17) when a disconnection occurs.
Moreover, if the value of "upper limit value + 5% of the input range" is 32767 or more when up scale is selected, 32767 is
stored.
Whereas, if the value of "lower limit value - 5% of the input range" is -32768 or less when down scale is selected, -32768 is
stored.

Processing at disconnection detection
The up scale value (upper limit value + 5% of the input range) of the input
range currently set is stored in CH Digital output value (RWr2 to RWr5) and
CH Digital output value (32 bits) (RWr10 to RWr17).
The down scale value (lower limit value - 5% of the input range) of the input
range currently set is stored in CH Digital output value (RWr2 to RWr5) and
CH Digital output value (32 bits) (RWr10 to RWr17).
The value set in CH Conversion setting value for disconnection detection
(address: 0110H to 0117H) is stored in CH Digital output value (RWr2 to
RWr5) and CH Digital output value (32 bits) (RWr10 to RWr17).
The value immediately before a disconnection occurs is held in CH Digital
output value (RWr2 to RWr5) and CH Digital output value (32 bits) (RWr10
to RWr17).
