Time Driven Sequencer Application Example
The following application example illustrates the use of the TON and SQO
instructions in a traffic signal at an intersection. The timing requirements are:
• Red light – 30 seconds
• Y ellow light – 15 seconds
• Green light – 60 seconds
The timer , when it reaches its preset, steps the sequencer that in turn controls which
traffic signal is illuminated. For a detailed explanation of:
• XIC, XIO, and T ON instructions, see chapter 6.
• SQO and SQC instructions, see chapter 1 1.
