Styrax PLC HVAC
Budget: $2 – $8 USD
Our factory’s HVAC automation runs on a Styrax Instruments PLC / controller network, and I’m ready to fine-tune it before full hand-over. The architecture is already in place, yet I still need focused help on the PLC/controller configuration so it operates flawlessly with our chiller loop and the rest of the HVAC plant.
Key focus
• Review the current Styrax program and hardware setup, then adjust parameters or logic that affect chiller control and feedback.
• Verify every RS485 Modbus RTU link, confirm register maps, and make sure the PLC exchanges data cleanly with our BMS/SCADA front end.
• Walk me through any code or register edits required to guarantee compatibility with the existing HVAC sequence of operation.
• Remotely support start-up, testing, and commissioning; I’ll be on site with VPN and secure screen-sharing ready.
Acceptance criteria
1. All chiller status, alarms, and set-points read/writable from the PLC and visible in SCADA without time-outs.
2. No CRC or framing errors on RS485 for 48 continuous hours.
3. Final controller logic documented and backed up in a version-controlled file sent to me in Styrax’s native format plus PDF printout.
If you have hands-on experience with Styrax controllers, industrial HVAC, and Modbus diagnostics—and you can collaborate online across time zones—let’s get this system running perfectly.
