PLATFORM SUMMARY
APPLICATIONS

Review program size, scan cycle, networks, motion control and machine-safety requirements.

Define the architecture around availability, redundancy, remote I/O, communications and engineering software.

Structure the control system around I/O scale, network topology and maintenance.

Begin migration review with the original program, module list, firmware, networks and wiring.
