1-Wire interface of iRidium server UMC C3 controller

Power supply and digital information via one wire

The documentation was updated on 02.12.2021

Advantages

1-Wire (MicroLan) is a digital interface that allows to send data from several devices at the same time via a twisted pair to the distance of 300 meters. 1-Wire is suitable for home automation. There are inexpensive digital temperature sensors and multichannel input-output modules, etc. on the market.

iRidium server UMC C3 supports devices only with microchips of DS18••• (Dallas Semiconductor) series.
1-Wire interface is optional. Check that your UMC C3 has it.

Connecting 1-Wire devices to UMC C3

Connect 1-Wire devices to the X6 terminal block (in the top part of the body).

Working in iRidium studio

Create a server project.

There are two ways to configure 1-Wire driver in iRidium studio:

to import tags from the server web-interface,
to set the driver manually.

Importing Tags from JSON file

1 Go to 1-Wire tab in the server web-interface.

Only UMC C3 controllers have 1-Wire tab.

2 Click Scan, IDs of devices found in 1-Wire bus will appear

3 Export data about devices as a .json file by clicking the Export button.

4 Go to your project in iRidium studio. Click a button to import the .json file (OneWire JSON Files).

5 A set driver with all tags appears in the project device tree. You can rename the tags.

Setting the Driver Manually

1 Add 1-Wire driver.

2 Set ContainerPath parameter - /sys/bus/w1/devices/.

3 Add required tags to the driver. Set a unique ID to each added driver.

Setting Commands and Feedback Channels

To control equipment it is required to set commands (Commands) and feedback channels (Feedbacks). To send a command, drag'n'drop it on a graphic item and enter a value to send. To display feedback value drag'n'drop a feedback channel on a graphic item and choose how to output a value.

Read more about work with graphic items in the "Types of graphic items" article.
