Schneider HMI & Control Solution for HVAC System

We need a a solution created for a Schneider Zelio based PLC controller (SR3B261BD) interfacing with a Schneider HMI (HMISTO501).

The solution will allow for the control of an existing multi-zoned HVAC system.

The functionality required via HMI includes but is not limited to:

- Monitoring of temperature and humidity in two zones, when system is engaged, heating, cooling and humidity

- Turning on / off exhaust equipment

- Monitoring status of heat / high heat / aux heat / cool and blowers

- Monitoring status of Temperatures

- Ability to have session and on-going timers for certain modes (i.e. Total hours exhaust used)

The solution will include:

- gathering of requirements and functionality from our users based on information we can provide;

- confirming the requirements with us, designing a solution that integrates the Schneider PLC and HMI along with other required components;

- programming of the PLC with the completed solution in FDM/SoMachine;

- design of the HMI functionality, layout and graphics in Vijeo Designer;

- specification of the additional parts required to complete the solution within budget of end user;

- providing documentation and/or remote assistance during installation / testing.

Control Items:

- Outputs

-- Summer Relay DPDT

-- Winter Relay DPDT

-- Exhaust Relay

- Inputs (Analog)

-- Temp - Fresh Air

-- Temp - Discharge Air

-- Humidity - Fresh Air

-- Humidity - Discharge

-Input (Digital)

-- Damper Status

-- Exhaust Status

Please include direct references to your experience with Schneider Zelio PLCs and related HMI equipment with your proposal.

Skills: Mechanical Engineering, PLC & SCADA, User Interface / IA
