Processor and Module Considerations
This chapter describes concepts that you need to understand to
program the fast analog I/O module in an SLC 500 system.
The following are processor considerations.
• Update processor analog I/O data
• Monitor analog I/O data
• Address I/O image words
The following are module considerations.
• Resolve data of the module’s I/O channel converters
• Convert analog input data
• Compute the analog input signal level
• Convert analog output data
• Compute the analog output
• Filter input channel
• Compute time delay for A/D conversion
• Determine response to slot disable
• Determine safe state for outputs
• Enter module ID code
