Chemical manufacturing demands absolute precision and uninterrupted uptime. Process control systems manage complex reactions, environmental controls, and quality parameters that have been painstakingly programmed and refined over decades. The failure of a single control point can halt production lines, compromise product quality, or create safety hazards.

Many chemical plants still depend on legacy VAX, Alpha, and OpenVMS systems that were originally programmed in FORTRAN and C during the 1980s and 1990s. These systems contain irreplaceable process knowledge, but the hardware is aging, vendor support has expired, and the technical staff who built them are retiring. Salem Automation specializes in preserving this critical investment while migrating to modern, supportable platforms with zero production downtime.
