Tunnel – Use of an MTX as local data-logger modbus local, without SIM card or GPRS connections
Scenario details: Over one month we intend to get the records of maximum and minimum temperatures in an industrial plant in order to perform a study on energy efficiency We want the MTX-Tunnel to work as a local data-logger modbus; that is, it acts and reads data without needing to send them to any web server. The […]
Tunnel – Advanced example for modbus devices reading and broadcasting to a web platform via a JSON object
Scenario details: We have 3 modbus RTU devices. It is recommended that the MTX-Tunnel polls them periodically sending the records to a web platform via a JSON object. The web platform requires login and password authentication The MTX-Tunnel must periodically poll, every 2 minutes and via its serial port RS485, the 3 ModBus devices. The records to read […]
Tunnel – Regular reading and delivery of Modbus records of a PLC + IP gateway for remote update of the PLC firmware to a webserver
Scenario details: We have a PLC Modbus RTU. This PLC has a series of variables/records (for example, a temperature value and 3 meters, etc.) in its internal memory, which must be periodically read and sent to a Web server In order to read said records, the MTX-Tunnel must periodically poll the PLC, every 15 minutes, […]
Tunnel – Regular reading of 3 Modbus temperature sensors and then sending to a webserver(Model MTX-Temp-RS485-IP65 of MTX accesories)
Scenario details: We have 3 temperature sensors MTX-Temp-RS485-IP65, which can be found in the MTX accessories catalogue of Matrix Electronica The MTX-Tunnel must periodically poll, every 10 minutes, the three temperature sensors, which use ModBus protocol. The modbus temperature record is 1. The ModBus addresses for the sensors have been previously set as 1, 2 […]
Tunnel – Reading and periodic sending of records of 5 Electric meters with ModBus RTU protocol and memory map for different records to a webserver
Scenario details: We have 5 electric meters with modbus RTU protocol. These meters have, in their internal memory, a series of variables/records (for example, accumulated and average consumption) that must be periodically read and sent to a web server To do so, the MTX-Tunnel must periodically question, every 15 minutes, via a serial port, the […]
Tunnel – Periodically obtaining readings from 5 electronic meters and sending them to a webserver using the ModBus RTU protocol
Scenario details: We have 5 electric meters with ModBus RTU protocol. These meters have a series of readings in their internal memory (e.g. cumulative consumption and average consumption) which should be read and sent to a Web server periodically Therefore every 15 minutes the MTX-Tunnel has to question the 5 meters to read the records […]
Tunnel – PLC Modbus RTU periodically registers readings, sends them as a JSON object to webserver
Scenario details: There is a Modbus RTU PLC. This PLC records some variables such as temperature, pulses, etc. in their register memory table from external devices connected to it. We need to read them and send them to a WebServer MTXTunnel will connect every 15 minutes to the PLC serial port. The number for storing […]
Tunnel – Modbus TCP/Modbus RTU 2G/3G/4G gateway.
Scenario details: We need to monitor remote ModBus RTU devices with the RS485 port from a central Server which has a software application to control ModBus TCP. MTX-Tunnel will create a ModBus TCP/ModBus RTU GPRS gateway ModBus remote devices need to be available at all times, so the modem connected to those devices is permanently connected to the […]
