Click PLC to Modbus TCP RTU Remote IO Controller BX MBIO

The Click PLC can communicate to remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces for remote IO. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication.
More information can be obtained on our website. This includes all of the links mentioned in this video.

Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

We will connect the Click Ethernet PLC to the Modbus remote IO. This will be done using the Modbus TCP and Modbus RTU protocol. Ethernet and serial RS485 communication to the BX-MBIO unit will be the media.
The BX-MBIO remote I/O expansion units feature the following:
• RJ45 Ethernet port for communications via Modbus TCP
• RS485 serial port for communications via Modbus RTU
• Supports up to 8 additional Expansion Modules (Add the discrete or analog I/O you require)
• AC and DC powered units available
• AC powered units include an integral 24VDC auxiliary output power supply
• Power connector and serial port connector included
Let's get started.

There are several reasons why we are using the Click PLC. Here are just a few.
- Investment is low for the hardware and the software is free
- Standalone PLC with built-in I/O
- Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc.
- Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.

background music is really annoying, but this is an excellent video. very helpful!

[@ACCautomation]

Thanks for the comment. I'm glad you found it helpful. Garry

[@mitchellkeeney3367]

Where are you getting the bits c40-c44?

[@ACCautomation]

Hi Mitchell Keeney, In the subroutines on rung 6, we are packing these bits into a word in order to use them on the remote unit. Regards, Garry

Excellent video. Is there a location I can download this example? I'm especially interested in the RTU subroutine. Sorry if you mentioned the location and I missed it. Thanks!

Hi Machine 27, Thank you for the comment. Each video has a corresponding web page post. accautomation.ca/click-plc-to-modbus-tcp-rtu-remote-io-controller-bx-mbio/ At the end of the post is the link to download the program. Here is the download location for this video. www.dropbox.com/s/no7e5omp1gmgt4z/Click%20PLC%20to%20Modbus%20TCP%20RTU%20Remote%20IO%20Controller%20BX-MBIO.zip?dl=0 Regards, Garry
