Configuration of the device

The device when used for the first time needs to be configured. There are two methods to do so. The network configuration can be easily changed by Inveo “Discoverer” (https://inveo.com.pl/software/) software:

6.1 Changing the device’s IP address by Discoverer applicatio n
When the “Discoverer” is opened and the relevant device is found, choose the Interface list box and click on Change IP button.

In a new opened dialog box, settings such as IP address, MASK, GATEWAY, DNS1/DNS2, and the Hostname can be changed.
Please save correct settings by choosing Change button.
If Remote Config is disabled (enabled by default), it is necessary to configure the device by changing the computer’s subnet (chapter 6.2).
To enable the remote configuration it is necessary to enter the Administration tab and mark Enable Remote Network Config.

Save the setup by selecting Save Config button.
6.2 Changing the PC’s subnet address, for the device configuration
After the device is connected to a network, a subnet address of a PC that is connected to the same network has to be changed. To do so, go to the PC’s MS Windows network configuration: Start->Control panel ->Network and Sharing Center->Network and Internet->Network Connections, choose the related controller, and right-click on „Properties”. After selecting this option configuration window will show up:

Next choose “Internet Protocol (TCP/IP)”, double click on it, and enter the following settings:

After saving changes by clicking OK, open an Internet browser and enter in the browser’s address line: 192.168.111.15.
Default user name/password: admin/admin00
In the Network tab, it is possible to change LAN parameters.

To change the network settings, use the following fields:

• Host Name – NETBIOS name,
• DHCP – checking this box forces use of the address assigned by the DHCP server,
• IP Address – the IP address of the reader,
• Gateway – network gateway,
• Subnet Mask – IP subnet mask,
• Gateway – network gateway,
• DNS1, DNS2 – DNS servers addresses.
• Destination IP – the IP address of the device in the M2M connection (chapter 7.3),
• Destination Port – the listening port of the external device in the M2M connection. After all changes, select Save Config.

6.3 Security settings and administration
The Administration settings allow for changing access passwords and to enable/disable particular services in the device.

Password change
To change the password, in the Current Password field write a current password. Next, in the New Password field write your new password and confirm it at the Re-type Password field.
Service settings
The device allows choosing which services are to be available. Selecting the check box next to the service name activates the selected service.
Enable Program Access – a service of access by a computer program (Windows, Linux) and TCP / IP protocol operating on port 9761,
Enable MODBUS TCP Protocol – enables Modbus TCP server,
Enable SNMP – enables SNMP protocol supporting,
Enable Destination Client – connecting to a remote host service (chapter 7.3), Enable MQTT Inveo – a service that sends data to the INVEO MQTT cloud, Enable Remote Network Config – remote configuration (via the Discoverer application),
Enable TFTP Bootloader – enables a bootloader.
Attention:
TFTP Bootloader and Remote Network Config ought to be disabled during normal work operations. It should be enabled for a firmware update only.

The device functions

7.1 Preview of the measured temperature
In the Home tab, the current temperature read from the sensor connected to the bus is displayed and the over-temperature condition is signaled.

7.2 Alarms
In the Channel tab, it is possible to set alarm thresholds. If the temperature is out of range, the alarm will be active.

Alarm Mode

• Off — alarm disabled,
• Lower — if the temperature is lower than value set in the Alarm Low field, the alarm will be active.
• Higher — if the temperature is higher than value set in the Alarm High field, the alarm will be active.
• Lower or Higher — if the temperature is lower than value set in the Alarm Low field or if the temperature is higher than value set in the Alarm High field, the alarm will be active.

Sensor Offset — the value that will be added to the measured value.
All changes must be confirmed with the Save button.
The occurrence of an alarm condition is signaled on the homepage of the module, and the display or LED is flashing.

If the alarm is active, the virtual output No. 1 is enabled **(

Attention!
If an alarm has occurred, return to normal device operation (without alarm signaling) will take place only after crossing the hysteresis zone equal to 1 degree Celsius. For example, if the Alarm Low is set to 20 degrees Celsius, the alarm will be activated when the temperature reaches 20 degrees and turns off when the temperature reaches 21 degrees Celsius.

7.3 Destination Client
Inveo devices such as LanTick, Nano Temperature Sensor, Nano Digital Input, Nano Relay Output, or others are able to send information data to the server or to another module with outputs using the TCP or UDP protocol. It means that this another module can react to activation of channel or when an alarm occurs (Nano Sensors). The message is sent each time state is changed and additionally every 5 seconds.
Configuration of devices receiving messages (external devices)
To enable the service, enter the Administration tab and select Enable Program Access and confirm with the Save Config button.
Configuration of devices sending alarm status messages
To enable the service, enter the Administration tab and select Enable Destination Client and confirm with the Save Config button.

In the Network tab, fill in the Destination IP and Destination Port fields.
The Destination IP field is an IP address of the external device or a server.
The Destination Port field is a port number of the external device (9731 by default).

Then, in the Channel tab select the appropriate output which will be enabled in the external device or – select type of the message.

The user can choose the following fields:

• TCP Ch:x – the function uses the connection protocol e. the TCP protocol. Number Ch:x is the selected output channel in an external device, e.g. LanTick, which will be enabled when the channel state of the local device changes. The TCP frame sends in the format #1,
• UDP Ch:x – the function uses the connectionless protocol e. the UDP protocol. Number Ch:x is the selected output channel in an external device, e.g. LanTick, which will be enabled when the channel state of the local device changes. The UDP frame sends in the format #1,
• Status – sends the device channel status, TCP frame sent in the format #2,
• MAC+Status – sends the MAC address of the device and current channel status, TCP frame sent in the format #3,
• HTTP GET – sends the MAC address of the device’s current alarm status and temperature value, a frame sent in format #4.

TCP frames formats
Format #1
The frame in format #1 is sent in binary form.
An example TCP frame sent with active alarm and Dest:5 set

An example TCP frame sent with inactive alarm and Dest:5 set

Values RAW_LSB and RAW_MSB is the temperature read directly from the sensor.
The temperature read off should be divided by 16
Value TEMP it’s the temperature without the decimal part.
Calculation of CRC:
CRC = (SOF+CMD+CH+F_ID+ALARM+!ALARM+TEMP+RES+RAW_LSB+RAW_MSB) MOD 256
Format #2
The frame #2 is sent as a string (STRING).
