0000 and 8000 = 0 and –0 are converted to 0 V
Hex Hex
87FF =
Hex
Data cannot be converted in ranges 0800
Example programs are shown below for the C500-DA103 Analog Output Unit
mounted in the C1000H.
The conversion data is stored in DM 0100. The Unit uses IR 000 through IR 003.
Only the programming for point 1 (IR 0000) is shown.
Output
10 V

2047 is converted to 10 V
–2047 is converted to –10 V
to 7FFF

The conversion data is transferred to
DM 0100
IR 000, then converted by the Unit.
