...completion, and proper PLC–SCADA integration so it can operate reliably in real site conditions. My approach will be to first analyze and stabilize the existing PLC structure, correct incomplete signal linking, and validate encoder and measurement behavior. I will then implement the proper calibration workflow and finalize key derived calculations such as ROP, gain/loss, and bit weight to ensure accurate and consistent readings. Once the core logic is verified, I will proceed with SCADA alignment — correcting tag mapping, trend plotting, and alarm behavior — followed by final validation. The work will be executed in phases with regular confirmations to ensure each step matches operational expectations and avoids unnecessary rework. Initial...

I need a compact, custom gateway that sits between an existing VAX / OpenVMS host (running DECnet Phase IV) and modern Windows-based SCADA software that only understands raw TCP frames. The current middleware is read-only; this replacement must provide full bidirectional READ and WRITE capability so I can both monitor and issue control commands in real time. Key requirements • Hardware: x86-class embedded Linux controller (Debian or Yocto are fine as long as the kernel exposes raw sockets). • Protocol handling: native DECnet Phase IV on one side; raw TCP frames on user-defined port numbers on the other. In addition, it should expose an OPC UA/DA endpoint for external clients that prefer that interface. • Data scope: “Real Time Data monitoring and control&...

Our production line runs entirely on an FA Feurer Automation PLC platform that now needs a careful round of maintenance and strategic upgrades. The immediate focus is on the core controllers and the associated communication networks that tie the line together. You will review the existing ladder logic and hardware configuration, identify firmware or parameter discrepancies, and then implement improvements that boost stability and cycle-time performance. After each change I expect clear documentation describing what was adjusted, why, and how to roll back if ever required. Because the install is proprietary FA Feurer equipment rather than a mainstream Siemens or Allen-Bradley rack, prior, hands-on experience with FA Feurer tools, programming environment and diagnostic utilities i...
