What a better-integrated Manufacturing Execution System (MES) can unlock:


Have you been frustrated by…
- Out-of-date Proficy Plant Applications versions that are hard to support and risky to upgrade.
- Operators who avoid the system because it is confusing and slow, creating spreadsheets and workarounds on the side.
- MES integrations that break whenever you change lines, products, or equipment.
- Limited visibility into real-time performance and quality, making it hard to hit productivity and OEE targets.
Your Proficy MES was supposed to make the plant run better. It is wrong for a Proficy MES investment to slow you down instead of speeding you up.
Turn Proficy into a modern MES that your operators actually use with Rain as your Proficy MES integration partner.


As Proficy-focused manufacturing systems integrators, we help you:
- Modernize and simplify your MES screens so operators can run production without fighting the system.
- Improve shop floor productivity with better workflows, real-time visibility, and fewer manual steps.
- Tighten security, standardize integrations, and reduce downtime across lines, sites, and products.
