## What is irBoard Lite?

Using irBoard Lite, you can conveniently monitor the status and operation of FA equipment and IoT devices through an iPad or any other iOS device.
The control device known as a PLC (Programmable Logic Controller) has communication protocols.  irBoard Lite communicates with PLCs via its protocol.
Additionally, it has the capability to communicate effectively with IoT devices, specifically the ESP32 device at present.
You don’t need additional software besides irBoard Lite because the screen editor is already included.

=====================================
irBoard Lite is a limited version of irBoard.
The Lite edition allows users to connect to only one project per day and the launch page only with a maximum of ten items.
And importing a project is not allowed.
To lift these limitations, you can either acquire an unlock item or redeem a ticket to access for four hours.
=====================================

FEATURE:
- You can conveniently monitor the status and operation of FA equipment and IoT devices.
- Although the FA equipment has fixed touch panels installed, the irBoard Lite on iOS devices offers superior portability.
- It is possible to remotely check the status of a device in PLCs.
- To ensure safety, manipulating connected PLC devices is only allowed on a single iOS device.
- By switching projects, you can easily connect to multiple FA machines using just one iOS device.
- irBoard Lite supports the following PLCs via Ethernet connection: MITSUBISHI Electric, KEYENCE, OMRON, and YOKOGAWA Electric, and support Modbus/TCP.
- It can also connect to an open-source PLC LadderDrive running on Raspberry Pi. (https://github.com/ito-soft-design/ladder_drive)
- The irBoard Library for ESP32 library supports ESP32 devices.(https://github.com/ito-soft-design/irboard_esp32)
- The irBoard.NET library supports Windows  .NET applications.(https://github.com/ito-soft-design/irboard-dotnet)
- Using the LadderDrive protocol, allows for communication with IoT devices such as ESP32 without any difficulty.
- The screen editor has already been included. it is easy for you to make modifications to the pages.

=====================================
--- Notes --- 

With irBoard Lite, you have the ability to turn devices on and off. If you require the interlocking of PLC-controlled devices, it is necessary to configure this on the PLC. To ensure safety, we suggest setting the status of such devices to read-only.

You can monitor the health status to determine if the connection is stable. If the connection is lost, it’s important to take precautionary measures when operating your PLC.
