Inputs 7 and 8
DM (m + 1)
Set DM word m+1 to "50AA" to set the desired input signal ranges.
Sets whether the digital conversion data is output in binary or BCD. The digital
data is output to IR words n+1 through n+8.
The scaling and square root functions can process BCD data only, so the data
type setting is ignored when these functions are being used.
Set the data type with bit 8 of DM word m.
The following table shows the range of data that is output to IR words n+1
through n+8.
Input range
0 to +10 V, 0000 to 0FA0
+1 to +5 V,
+4 to +20 mA
–10 to +10 V 87D0 to 8001, 0000 to 07D0
(–07D0 to –0001, 0000 to 07D0)
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.
