9.4.1 Programming the KV-AD4
This section describes the A/D conversion mechanism, and the digital data that is
written to the CPU by the KV-AD4 after A/D conversion. It also describes how to
calculate actual voltage and current values based upon the digital data written to
CPU.
A/D Conversion Mechanism
This item describes the A/D conversion mechanism on the KV-AD4. Check this item
before writing sequence programs for the KV-AD4.
1. The analog signal (voltage or current) is input to the KV-AD4 from the external
instrument.
• This operation is called "analog input."
2. The KV-AD4 converts the analog signal to digital data.
• This operation is called "A/D conversion."
3. The KV-AD4 then writes the digital data to the data memory for A/D conversion
on the CPU.
• Digital data is automatically written at each scan.
➮
For details, see "About Digital Data after A/D Conversion" on the next page.
4. If necessary, the digital data is processed by the sequence program on the CPU.
• The value of the actual input voltage or current can be calculated from the
digital data.
➮
For details, see "Calculating Voltage and Current Values from Digital Data"on page 1-352.
The calculated values can be used for further processing besides the sequence program.
• The digital data can also be output as analog data as it is.
