# ControlBus

> ControlBus designs industrial IoT products: custom circuit boards and embedded firmware, edge systems, and the software that connects equipment in the field to the people who run it.

RYDM, rail yard fuel control, is the first ControlBus product line. A second, for greenhouse and farm technology, is in development.

## What we build

Source: https://controlbus.com/

### 1. Circuit boards and firmware

Custom PCBs and embedded firmware, designed for the sensors, controllers and conditions of the job.

### 2. Edge systems

Devices and gateways on site that read PLCs, meters and sensors and carry their data to the cloud.

### 3. Software

Applications, reports, alerts and integrations for the people accountable for the operation.

## Product lines

### RYDM

In service, rail yard fuel control. Tanks, meters, nozzles and AEI tag reads at locomotive fueling facilities, on the equipment already in the yard. Details: https://rydm.com/

### Greenhouse and farm technology

In development. Sensing and control for greenhouses and farms, built on the same circuit boards, edge systems and software as RYDM.

## How a product comes together

### 1. Learn the operation

We start on site: the equipment, the conditions, the controllers already installed and the people who answer for the result.

### 2. Design the board

Schematics, PCB layout and embedded firmware for the sensors and controllers the product has to read and run.

### 3. Prove it in the field

Prototypes are brought up, tested and run on a real site with our partner before anything is built at scale.

### 4. Deploy and support

Edge systems go in with the partner who services the site, and the software turns their readings into records and alerts.

## Three rules we build by

Source: https://controlbus.com/engineering

### 1. Design the whole stack together

Circuit board, firmware, edge and software are designed as one system, so the reading taken in the field is the number people act on.

### 2. Work with what is installed

Our products read the PLCs, meters and sensors already on site. Nobody should have to replace working equipment to get good data from it.

### 3. Build with the operators

Each product line is built with a partner who runs the operation or services it in the field. For RYDM, that is CWI Railroad System Specialists.
