When is the best time to upgrade a decades-trusted PLC system? This was the challenge for a global supplier of spice ingredients. Their Allen Bradley PLC-5 system was commissioned over 25 years ago and, while it performed well for many years, the outdated platform began experiencing constraints. The obsolete equipment was limiting network connections. This urged the global spice supplier to seek a system integrator that could provide timely PLC migration support using the latest technology available. Automation Group was recruited to modernize their obsolete PLC system to a more IIOT friendly platform.
