F2-8AD4DA-1 Analog Input/Output - continued
Input Resolution Selection (WYn+4)
If not using Do-more Designer version 1.1 or newer, each of the eight input channels can
be individually configured for 12, 14, or 16 bit resolution or disabled with memory address
WYn+4 (WYn: Starting WY address assigned to this module). Two (2) bits in this memory
address are assigned to each analog input channel.
The HEX data format is used to set up the input resolution as seen in the following example.
Example: An F2-8AD4DA-1 is installed in slot 0 and WY4 is used for the input resolution
selection. Input channels 1-4 are 12 bit, channel 5 is 14 bit, channel 6 is 16 bit, and channels
7 and 8 are disabled. In this case, 0xF900 needs to be written into WY4.
Use the MOVE instruction to write the Hex value 0xF900 into WY4.
