For the last eight months we’ve been converting a proprietary control system to an Epic Groov based system. We had to reuse the existing cabinets due to space limitations so the arrangement is slightly goofy.
The original system was monolithic - it had one controller for all three cabinets connected via some flavor of RS485. With our approach we split it into three separate systems which had the added cost of extra controllers, but without the division the upgrade was not deemed feasible given the site constraints.
We did everything in-house - design, assembly, programming, and install. Overall fairly happy with the outcome
