TeleEco - LoRa wireless transfer of analog and discrete industrial signals

Built on modular principle – up to 6 input-output boards can be installed in each TeleEco.

There are many engineering tasks where the use of a cable is impossible or too expensive or too complex. TeleEco helps to solve such kind of problems. TeleEco is effective when:

- it is necessary to overcome obstacles - rivers, railways, roads, concrete platforms, fields, rocky or forest terrain;

- the sources and/or receivers of signals are mounted on mobile equipment such as excavators, electric buses, units in wastewater treatment plants, etc.;

- transmitting signals over long distances, where the use of control cables is expensive;
- due to absence of power supply to remote sensors.

Description

TeleEco devices provide wireless data transmission of standard industrial analog and discrete signals, and wireless transmission of data received via a serial RS485 interface as well.

TeleEco works as a replacement of control cables connecting signal sources and signal receivers. Data received at the input of one device is transferred to an analogical output in another device. Copying data from an input to an output is automatic.

TeleEco devices are modular based and allow configurations with different number and functionality of input-output modules. Each TeleEco device can contain up to 6 input-output modules. This gives flexibility to the new automation systems, as well as an ability easy to expand existing systems.

In addition to standard inputs and outputs, TeleEco also has an RS485 interface for connecting external sensors via Modbus RTU protocol. In this case TeleEco is a Master and the external sensor is a Slave.

The following types of data are transmitted by TeleEco:
• Status data about the own discrete and analog inputs
• Status data about the own discrete and analog outputs
• data about the values of Modbus registers, received from external sensors via RS485.

Communication technology

Built-in TeleEco is LoRa^® technology, operating in ISM 868 MHz frequency range and with low power consumption (LPWAN), providing data transmission at distances of up to 20 km.

Communication Topologies

TeleEco can work in systems based on the following communication topologies: "point-to-point", "full mesh" and "star".

• Point to point topology - a pair of devices communicate with each other, each of them transmitting the states of its input signals to the other device, and the data is replicated to corresponding output signals, i.e. the inputs on one side are copied to the outputs on the other and vice versa.

• Full mesh topology - each device transmits the states of its own inputs to another device or to all other devices in the system, and each device receives on its outputs data about the input states from one or more remote devices.

• Star topology – a special TeleEco device with a gateway functionality is necessary. All other TeleEco devices in the system send data about their inputs, outputs and Modbus registers to this central TeleEco gateway. The TeleEco gateway publishes both the data from the remote devices and data about its own inputs, outputs and Modbus registers to a MQTT broker. It is also possible at data change in the MQTT broker the gateway to send a control command to the outputs of each device in the "star" network.

TeleEco models according to their functional characteristics

Depending on the functions executed by the device, TeleEco can be:

- TeleEco Node - performs basic functions as periodically sending of its inputs, outputs and Modbus registers status to one, several or all devices in the LoRa^® network. The Node function can be performed by every TeleEco hardware model.

- TeleEco Gateway - in addition to performing the functions of a Node, the TeleEco Gateway also works with a MQTT broker, connecting all inputs, outputs and Modbus registers belonging to all devices in the LoRa^® network to topics from this MQTT broker. The Gateway function cannot be performed by the solar-powered TeleEco2 model.

TeleEco hardware models

Input/output modules for TeleEco. Up to 6 different input/output modules can be placed in one TeleEco device.

Configuration – via a web configurator.
