MKY44-AD16A
|
CUnet slave IC, two 16-bit AD channels + DIO |
 |
|
The MKY44-AD16A is a CUnet station (hereafter "slave") IC with analog input function. |
||
AD capture and DO output speeds depend on the cycle time of the CUnet network.
For analog input, the data acquisition timing can be selected from 5 modes.
Analog input data is automatically input to the MKY44-AD16A's self-owned memory block.
The input data is automatically copied to all CUnet ICs through CUnet communication (memory sharing), so the user CPU can acquire analog data easily just by reading the memory blocks corresponding to each slave IC.
Existing users of CUnet can get analog input just by adding this product to their networks.
New users have the opportunity to reduce A/D wiring that used to use parallel connections and to achieve easy, networked analog input.
