Click PLC to Click PLC Communication RS485

This video will show you how to use Click PLC to Click PLC communication using serial RS485. This communication method allows you to control Click PLC remotely using Modbus RTU.
By showing you this example, we hope to provide you with a better understanding of how this communication method works and help you to use it in your own projects.

We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs.
The send and receive commands have been covered before in our Click PLC Series, but we will look further at the timing of the communication. Detecting and correcting communication errors will be discussed and implemented. We will also create a heartbeat for the remote Click slave (server) PLC. This will allow the remote controller to determine if communications have stopped with the Click master (client). Wiring a pushbutton and some ladder logic code will allow us to time the throughput of each of the communication methods.
CLICK PLCs were designed with simplicity, providing reliable control at a low cost and with little to no learning curve.
This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications, or anywhere a simple system needs a budget-saving control solution.
Building on the original CLICK’s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging.

Features of the new Click PLUS PLC (C2-0xCPU) include the following:
• Micro USB
• DHCP support
• DNS support
• Wi-Fi (programming and Modbus TCP)
• Bluetooth (Wi-Fi) provisioning
• SD Card (Data Logging)
• Data Logger
• Network Time Service
• MQTT (Publish/Subscribe)
• Required PLC Password
• Disable Ports
• Strong Password Support
• Disable Ping Response
• Encrypted Password Transfer
We are using the Click and Click PLUS PLCs for several reasons. 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 directly expand the system with various modules, including RTD and Thermocouple inputs.

in the slave i would connect t11 to an output so I know if comm is lost.

The heartbeat bit from the Modbus RTU Master would pulse in the slave. You would start a timer for the pulse bit off and a separate timer for the pulse bit on. If either timer times out, then communication has failed. Regards, Garry
