Sample Programs
Program Example
The following program can be executed only with the C200HS, C200HX/HG/HE CPU Units.
• Data Flow (Unit Number 0): Word 101 (AD Conversion Value) → DM 0001 (Mean Value Result)
Execution condition
The number of samplings will be no more than 64 when the AVG instruction is used.
Sample Program 9: Peak Value Holding
This is a program for Analog Output Unit peak value holding. If the output value range is exceeded, the output
voltage or current is held when the Conversion Enable Bit turns OFF.
