The Importance of PLC Migration

Programmable Control Systems have been evolving rapidly in the last 30 years. PLC Manufacturers have made major changes and upgrades to their equipment. Managers and Plant Engineers have found that it has become increasing difficult and expensive for their staff to maintain and support these legacy PLC systems.


To support your PLC migration efforts - give Systems Interface a call!

Systems Interface engineers are familiar with Allen-Bradley, Siemens, Texas Instruments, GE, Toshiba and other manufacturers.


PLC's that were installed in the 80's and early 90's are reaching the end of their life cycle and it is time to upgrade them. Systems Interface has been working with many of our clients to make these upgrades. The two pictures below are from a recent conversion. The picture on the left is a legacy Allen-Bradley PLC 5 Control System shown prior to the conversion. The picture on the right is the same panel after Systems Interface upgraded it to a Rockwell Automation CompactLogix ® PLC System.

On PLC Migration projects of this nature,Systems Interface will work with you to upgrade the original schematics, convert the ladder logic to the new platform and fully test the control system once installed.


The amount of downtime required can vary, and we can schedule the migration to have minimal impact on your plant. We can arrange for after hours, weekend, or scheduled maintenance downtime as well.



If your plant is ready for a PLC Migration project, please give us a call to get a proposal.
