PLC-5 and SLC500 controllers have been around a long time, but the time has come when they no longer provide the capability that modern production systems demand. Support for these systems becomes very expensive, as spare parts become more difficult to obtain, and experienced technicians leave the field. Though refurbished equipment may be available from specialty companies, the quality of these controllers can often cause problems, as there is simply no way to equate their reliability with that of a new control module that has a full warranty. Additionally, manufacturers may no longer support their old PLC-5 software, making programmability and security a very real concern. The time has come to upgrade to the current technology and Grantek is prepared to help.

Grantek’s extensive industry experience ensures that systems will experience minimal downtime during migration of legacy systems to new controllers. Grantek is a certified Rockwell Automation Systems Integrator; we are experts at replacing out-of-date PLC-5 equipment with current Rockwell ControlLogix equipment. Grantek can even replace older systems that may still be in production if necessary, such as PLC 2 and PLC3.

Grantek always begins by auditing the current system to determine whether it is currently providing the functionality needed, meets with machine and process operators to analyze the PLC programming code and other inputs that interact with the system, completes necessary re-engineering, including interactive panel design, custom build, equipment procurement, risk analysis and a Site Acceptance Test. Finally, Grantek analyzes system documentation for completeness and accuracy, providing updated documents reflective of the new system after migration is complete.

Advantages of working with Grantek include our extensive experience, but also our close relationships with partners such as Rockwell Automation, which ensure our engineers receive ongoing training on current products. Grantek also holds Cisco network certifications and have vast experience working with Festo, SMC, SICK, and other sensor manufacturers.

Grantek’s systematic and holistic approach to Legacy System Migration provides an upgraded system that will perform as it has in the past, but with reduced risk of failure and more efficiency. It will also be easier and less costly to maintain as the production environment changes.
