Scenario details:
- 2 analog sensors need to be monitored, one 0-10V and the other 4-20mA
- If the 0-10V sensor registers a voltage greater than 8V or less than 2V, an alert voice call must be made to a series of telephone numbers
- If the 4-20mA sensor registers a current greater than 16mA or less than 8mA, an alert voice call must be made to a series of telephone numbers
- The phone numbers that will receive the alert calls are +34666123456, +34666123457 and +346661234568
- To avoid sending a high number of calls (when the measured value is just within the alarm limits), a hysteresis of 100mV must be configured for the 0-10V sensor and 0.5mA for the 4-20mA sensor.
- A timeout of 5 minutes per input must also be established, that is, no more than 1 call will be made in a 5-minute window due to the activation of a certain analog input
Solution: MTX-Tunnel firmware + MTX-IOT-S [4-N]
Configuration example (config.txt file) for the indicated scenario:

Details:
- The configuration of the inputs as “call; 1; 300” indicates the following:
“call” > The input is configured to send alarm by voice call (the voice call will be made, but will not play any audio on the other end of the phone)
“1” > The 2 indicates that the digital input is configured to make the voice call by activation of the input (when it closes taking it to ground)
“300” > Indicates the timeout of the digital input, in seconds. This means that, even if there are multiple changes in the digital input, there will never be more than 1 call in a 5-minute window (5 minutes = 300 seconds)
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.
