Details of the example scenario:
- We need to provide Internet connectivity to a network analyzer with an Ethernet interface. The LAN IP address of the Ethernet device 192.168.1.70
- We also have 3 Modbus RTU modules. One of them, with address Modbus1, is to ready 8 digital inputs. The module with address 2 allows us to read 2 analog inputs (4-20mA). The module with address 3 has 8 relay outputs
- We can change Relay1 in module 3 (by writing “1” in register 1) when the digital inputs 1, 2 and 3 (registers 1, 2 and 3) in module 1 are activated (all three of them have the value “1”). Also, Relay2 in module 3 will be changed (writing 1 in register 2) when the digital entries 4 or 5 (registers 4 and 5) in module 1 are not activated or when the analog input 1 in module 2 has a value of 10mA or less. Finally, an SMS alert should be sent and an internal relay in the Titan minidevice should be changed when the second analog input in module 2 has a value greater than 18mA
Solution: MTX-Router-Titan mini
Configuration example ready for use:
We can easily load the example from the router’s web configuration environment from the menu “Other>Backup / Examples”.
Details:
- After loading the configuration on our router, we can access the router’s configuration with the default username and password: “admin” and “admin” and the IP address “192.168.1.2”
- Check the configuration in the menus “Wan>Basic Settings”, “LAN>Basic Settings”, “Serial Settings>Serial Port 1”, “Other>Titan Scripts”
Details (2):
The exact meaning of the scripts is:
Condition: [If register 1 of the device with address 1 is equal to 1] AND [If register 2 of the device with address 1 is equal to 1] AND [If register 3 of the device with address 1 is equal to 1]
If true: write “1” in register 1 of the device with address 3
If false: write “0” in register 1 of the device with address 3
Condition: [If register 4 of the device with address 1 is equal to 0] OR [If register 5 of the device with address 1 is equal to 1] OR [If register 1 of the device with address 2 is greater than or equal to 1]
If true: write “1” in register 2 of the device with address 3
If false: write “0” in register 2 of the device with address 3
Condition: [If register 2 of the device with address 2 is greater than or equal to 18]
If true: send an SMS to the telephone 666274646 with the text “alert value: [the current value of register 2 in the device with address 2]” AND activate the Titan device’s relay 1
If false: desactivate the Titan device’s relay 1
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.
