DO-1 enables the integration of different manufacturers of measured value monitoring devices and sensors, which use the Modbus standard RTU or

TCP

, into a monitoring network. The variety of devices offers numerous application possibilities. You can customize monitoring and visualization via user-defined dashboards and configure alarm functions and user rights and roles individually. Plus, there are no license fees for DO-1.

A wide range of parameters and conditions can be monitored with the help of measured value monitoring devices or sensors. Example: In a warehouse, various sensors are used for monitoring and safety to ensure the conditions and protection of goods and employees. These sensors are monitored using DO-1.

DO-1 allows you to monitor a variety of parameters and conditions. Among others:

• Temperature
• Humidity
• Pressure
• Motion
• Light
• Sound
• Gas
• Liquid level
• Distance
• Air quality
• Vibration
• Current
• Voltage
• Energy
• Water quality
• Position

The areas of application are diverse and range from industry to healthcare. Sensors capture data, control processes and improve safety in various areas:

• Temperature: Use in heating, ventilation and air conditioning (HVAC) systems, process control, weather monitoring and healthcare.
• Humidity: HVAC control, sensitive goods storage, agricultural monitoring and precision manufacturing.
• Pressure: Industrial process control, hydraulic and pneumatic systems, weather forecasting and geotechnical.
• Motion: Security systems, building automation, automotive and robotics.
• Light: Lighting control, light sensors for imaging, street lighting and environmental monitoring.
• Sound: Noise level monitoring, quality assurance, acoustic measurements and environmental noise monitoring.
• Gas: Gas detection in industrial plants, carbon monoxide monitoring in homes, environmental protection and safety.
• Liquid level: Level monitoring in tanks and vessels, water management and process industry.
• Distance: Positioning in robotics, object detection in vehicles, automatic door opening and obstacle detection.
• Air quality: Indoor pollutant monitoring, environmental monitoring and healthcare.
• Vibration: Structural monitoring, machine condition monitoring, earthquake detection, and vehicle dynamics.
• Power: Energy management, electrical load monitoring, electromobility, and electrical equipment monitoring.
• Voltage: Power supply monitoring, power supply quality and battery monitoring.
• Energy: Energy management, consumption monitoring, solar system monitoring, and electric vehicle charging stations.
• Water quality: Water parameters monitoring in drinking water systems, environmental protection and water treatment.
• Position: GPS tracking, navigation systems, aircraft guidance, vehicle tracking and robotics.

Please follow the steps described in the user manual for device installation and configuration.

No, the DO-1 is supplied with pre-installed software so that no additional software is required. The device can only be addressed via its IP address. However, if the IP address is unknown, a specially developed program is available for download under DO-1 Device Finder. This program locates the DO-1 in the local network (LAN) and provides information such as type, IP address, location and port details.

The device has the following dimensions: width 55mm, height 30mm, length 71mm and weight 130g.

Currently only two versions are available:

• A stand-alone version
• A version with an adapter for the 35mm DIN rail.

The device has an internal memory of 5 GB, which can be expanded up to 128 GB using an SD card.

Yes, you can individually adapt the settings to the connected measured value monitoring devices or sensors from different manufacturers. You also have the option to customize digital monitoring and visualization via dashboards. Alarm functions, user rights and roles are also customizable.

You can integrate devices that communicate via RS-485 and are equipped with an RS-485 port. This port can be in the form of simple screw terminals, a DB9 connector or an RJ45 connector. In addition, you can integrate devices that support Modbus TCP.

No, in a 2-wire RS485 (Modbus RTU) network, only one Master is supported. However, in an Ethernet Network or LAN (Modbus TCP), multiple clients (masters) can be accommodated as each client has a unique IP address.

While the functionalities are similar, the terminology used (master-slave vs. client-server) distinguishes between the roles and interactions of devices within a Modbus network. Master-Slave configuration is used in the Modbus RTU protocol, whereas Client-Server configuration is used in the Modbus TCP protocol.

It is recommended to use a 2-core shielded and twisted cable for signal transmission.

The integration of Selec device templates offers several advantages. It significantly reduces implementation time, especially without specific device selection from other manufacturers. In addition, Selec devices are tested to work with DO-1 and offer excellent value for money.

Alarms can be displayed via email, on the dashboard, and can also be signaled audibly or visually using an RS-485 output module.

Yes, by using an RS-485 output module.

To access DO-1, both the DO-1 and the computer, laptop, tablet or smartphone must be on the same network (LAN). You can then access the DO-1’s web-based user interface using any web browser.

The device is switched on and off by plugging or unplugging the green 2-pin connector connected to the 12-24 V power supply.

The most common problems are related to RS-485 communication, especially physical wire connections and communication settings. To solve these problems, carefully follow the instructions in the Troubleshooting RS-485 communication problems section. In addition, problems and errors can occur due to device and register requirements of different manufacturers. Many manufacturers interpret the Modbus standard differently, which can lead to confusion, especially when reading Modbus registers, because different terminologies are used.

Many manufacturers interpret the Modbus standard differently, which can lead to confusion, especially when reading Modbus registers, as different terminologies are used depending on the manufacturer.

Log in to DO-1 (through the Web GUI) as an administrator, click on the ‘System’ menu item and then click on the ‘Status’ menu item. In the ‘Updates’ tile, check for an update by clicking on the appropriate button. Follow the instructions.
