Tunnel – Relays control, MTX modem digital and analog inputs from a SCADA system using Modbus TCP protocol
Scenario details: It is necessary to control 4 relays located in 3 locations, as well as 4 digital inputs and 2 analog inputs. This will use 3 2G/3G/4G modems, each in a different location The communication will be made from a SCADA system using Modbus TCP protocol For simplicity it is intended to use SIM […]
Tunnel – Periodical sending of vehicle’s GPS locations and the registers of Modbus RTU temperature sensor RS485 to a Web server. Occasional 3G-5RS232 gateway for PLC’s firmware actualization
Scenario details: We have a truck whose GPS location and temperature of the 3 temperature sensors should be monitored. The truck is also equipped with a control PLC with RS232 serial port.There should be the possibility to update the PLC’s firmware remotely by the above mentioned serial port at any moment The modem must collect […]
Tunnel – Reading and sending Modbus registers from a PLC to a webserver. Remote and occasional access to PLC registers in real time and for remote update of PLC’s firmware
Scenario details: We have a PLC Modbus RTU. In its internal memory this PLC contains a number of variables/registers (for example, one temperature and three counters,…) which should be read and sent periodically to Web server Therefore, MTX-Tunnel should request periodically (every 15 minutes) the PLC through a serial port in order to read the […]
Tunnel – Reading and writing Modbus registers via SMS
Scenario details: We have a PLC with Modbus protocol and address 1 It is necessary to read different Modbus registers via SMS. Register 10 (current temperature), register 12 (pressure) and register 14 (current humidity) It is also necessary to be able to write “1” via SMS in Modus16 register. This way the PLC will activate […]
Tunnel – Reading modbus Word and Binary registries, sending data to webplaform using JSON object
Scenario details: We want to read 12 modbus registers from a PLC 10 registers are binary and and the other 2 are word. It is necessary to use the modbus command 0x01 to read binary registers and the 0x03 modbus command to read word registers. Binary registers are in the addresses 10,11,12, … 17 and […]
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 […]
Enter the “ethernet” or “modem” connection type:
For an ethernet configuration, make sure the IP parameters are compatible with server access according to the concentrator local network configuration. For an ethernet connection, the configuration must be compatible with the concentrator’s local network topology so that it can access the servers. This configuration is done from the “Networks” configuration page (see section 3.2.2.3: “Networks”).
For a modem connection, the modem configuration must be correct before a connection can be set up. This configuration is done from the “Modem” configuration page (see section 3.2.2.4: “Modem”).
The parameters for the servers to be configured are at least the following:
Therefore the following fields need to be configured: “Interface”, “Type”, “Server type”, “Address”, “Port”, “Login” and “Password”.
The other fields can be left at the default values subject to the directories having been properly created beforehand. See section 3.1.2: “Configuration files” for more details.
Wait. The concentrator will reboot using its factory configuration.
