2-8 Quick Start for Experienced Users
9. Understanding analog outputs. Reference
Analog outputs convert 16-bit integer values placed in the output image to voltage or current
signals for the slot that the analog card is in. Chapter 4

10. Write ladder logic to process the module’s analog data. Reference
Several programming examples are provided in chapter 6 that demonstrate how to scale the raw
data from the analog card into engineering units such as psi, percent, etc. Study these examples
and apply them to your application as appropriate. Chapter 5
