Program Example
• Data Flow (Unit Number 0):
Word 2001 (A/D Conversion Value)
→
Words 0201 and 0200 (Conversion Result)
(1) If the leftmost bit is a 1 (negative number) in 16-bit binary data, the data is reversed and the leftmost word
becomes F000.
(2) 16-bit binary data is converted to BCD.
(3) Signed BCD data is output to words 0200 and 0201.
Square Root Calculation
Data expressed as quadratic curves, such as thermocouple inputs, is converted and output to linear data (0000
to 4000).
