TecoRoute

The TecoRoute package provides software components for better usability of the TecoRoute service from Teco a.s. It consists of TecoRoute server and EPSNET connector.

For the proxy server, which automatically authenticates the user to the TecoRoute web interface, see TecoRoute Proxy.

Components

TecoRoute server

With the SetPlcIp utility, it is possible to set the address of TecoRoute server for the PLC, so there is no restriction to using Teco's TecoRoute service, but it is possible to have a private server.

The TecoRoute server is not fully opensourced yet. Please contact Czetech at hello@cze.tech for this component first.

TecoRoute EPSNET connector

The TecoRoute connector provides various types of EPSNET access to the PLC via the TecoRoute service. By default, the connector is authenticated as Teco's Mosaic, so on the portal this application must be enabled for the user.

Command-line interface

The basic functionality of the components can be invoked from the command-line. Currently, there is only one mode of operation, which is the UDP connector.

Connector

Connector locally opens UPD port 61682, which can be accessed in the same way as the PLC in a local network (e.g. communicate using EPSNET or connect to Mosaic). Example:

tecoroute connector \
  --mode udp \
  --username BroukPytlik \
  --password ferda1 \
  --plc AB_1234

The program terminates in case of any error (for example, temporary loss of connection), so it is up to the user to start the program again.

For all options, run tecoroute connector --help.

Library API

Thanks to the library's asynchronous design, it is possible to operate thousands of connections at the same time very efficiently.

As in the command-line example, in Python the UDP connector starts with the code:

from asyncio import run
from logging import INFO, basicConfig

from tecoroute.connector import UdpConnector

basicConfig(level=INFO)


async def main():
    connector = UdpConnector(username='BroukPytlik', password='ferda1',
                             plc='AB_1234')
    await connector.run()


run(main())

There is an example of the implementation of simultaneously running connectors according to the data from the MariaDB table at https://github.com/czetech/tecoroute-manager.
