❏ Prepare a general description of how you want your
automated process to operate.
❏ Identify the hardware requirements.
❏ Match inputs and outputs with actions of the process.
❏ Add these actions to the functional specifications.
Do you need:
❏ Special interrupt routines?
❏ High-speed counting features?
❏ Sequencing Operations?
❏ FIFO or LIFO stack operations?
❏ Make sure I/O addresses match correct input and
output devices.
❏ Enter program using the MicroLogix 1000 HHP.
❏ Review your functional specification and detailed
analysis for missing or incomplete information.
The resulting program should match your
functional specification.
❏ Monitor and, if necessary, troubleshoot the
program that you entered.
Start program in RRUN,
RCSN, or RSSN mode.
