+Are you looking for an affordable temperature measurement solution, need to read the temperature at longer distances, or want to automate a boiler room? Then the [[https://www.unipi.technology/unipi-extension-xg18-p331|Extension xG18]] is the ideal solution.
 This compact module is designed as a simple and reliable tool capable of reading temperature from up to 8 Unipi 1-Wire temperature sensors (DS18B20). Modbus RTU protocol on RS-485 serial line is used to provide the data to the control system.

 Each 1-Wire channel is dedicated for just the one 1-Wire sensor with a RJ45 connector, which highly increases reliabily of the measurements.

 ===== 1 Connecting xG18 to an Unipi PLC =====
-Extension xG18 communicates with the PLC using a two-wire RS-485 connection. The module can be powered by the same power source as the PLC (if the power supply's specification allows it). Alternatively, you can use a standalone 5-24V DC power supply. As to temperature sensors, simply plug them into the available RJ45 ports.

 ===== 2 Attaching the xG18 to a Mervis IDE project =====
 Create a new project or integrate the device into an already-existing one. Follow the steps below:
+<WRAP center round box 95%>
+In case of adding the module to an already existing Modbus RTU channel, make sure the communication parameters (parity speed, etc.) are set correctly. If so, continue with [[#automatic_detection_using_module_autodetect|Chapter 2.1]].

-You can use an existing Modbus RTU channel (if you have one). In this case, you need only to ensure all communication parameters (bitrate, parity etc.) are set correctly.
+Alternatively, create a new channel. Right-click on the PLC's name and choose **Add Channel**. Set its name to **Modbus_RTU**.
-Alternatively create a new channel. Right-click on the PLC's name and choose ''Add Channel''. Set its name to **Modbus_RTU**.
