Note When the input range is set to –10 V to +10 V, the 15
status of 0 indicates "+" and a bit status of 1 indicates "–." There is no sign bit
when the scaling or square root function is being executed.
When scaling, mean value processing, peak value, or square root calculation is
executed, the resulting data is output.
Note When scaling is executed, it is set in IR words n+1 through n+8 in BCD.
Item
Not used. Set these bits to 00 (OFF).
Turn these bits to 1 (ON) to execute the peak value function for the
corresponding input. Bits 00 through 07 correspond to inputs 1
through 8.
Refer to 2-3-7 Peak Value Function for more details.
Item
The A/D conversion data is set here for each input.
The conversion data range is as follows when the input signal range The conversion data range is as follows when the in ut signal range
is set to 0 to 10 V, 1 to 5 V, or 4 to 20 mA:
The conversion data range is as follows when the input signal range
is set to –10 to 10 V: i

being executed.) being executed.)
The processing results for the scaling, mean value, peak value, and
square root functions are output here when those functions are being square root functions are out ut here when those functions are being
executed.
When the limit warning has been set, these bits are turned ON to
indicate that the corresponding input's value has exceeded the
range. Bits 08 through 15 correspond to inputs 1 through 8.
These bits are turned ON to indicate that a disconnection or broken
wire has occurred in the corresponding input. Bits 00 through 07
correspond to inputs 1 through 8.
