Suppanel Android HMI to Click PLC

Suppanel is an Android app that is used to create a human machine interface (HMI). This HMI panel can be created on your computer, tablet or phone using the appropriate operating system or software. You can use this software to create panels that you can control or modify values in your automated system. These panels can be shared with other Suppanel users.

We will be creating a Suppanel Panel to monitor and control a Solo Process Temperature Controller via the Click programmable logic controller (PLC). The Click will be communicating to the Solo with serial RS485 using Modbus RTU protocol. The Suppanel HMI will be communicating to the Click PLC using Ethernet Modbus TCP protocol.

Let’s get started.

Suppanel Installation
Install the Suppanel software on your android device. The software requires android 4.1 or higher versions. A 60 day trial is automatically started when you install the software.

Open the Google Play Store and search for Suppanel. You can also click the link below.
https://play.google.com/store/apps/details?id=com.suppanel.suppanel&hl=es

If you are running on a windows machine, you can use your chrome browser and run ARC Welder to run the Suppanel application.

This is the method that we are using in the video below to demonstrate our communications to the Click PLC.
Note: ARC Welder will not allow In-App Purchases so you will only have 60 days for a trial period.

Click PLC Program
We will be using a modified version of the program that we demonstrated the send and receive commands in the click. Here is the post that will describe the setup of the Solo process temperature controller and the Click PLC.
https://accautomation.ca/click-plc-send-and-receive-instructions/
The communication to the solo uses port number 3 (RS485). This is a twisted pair serial communication with the Modbus RTU protocol.

Here is our program:
Click PLC Communication to Solo Process Temperature Controller
Set up the time for each of the communication instructions to be executed.
In our case 50 ms timer is used.

Communication Timing Sequence
We use a shift register that will self reset. This way we ensure that only one bit is on at a time for our communication. The bit get shifted based on the timer T1 above.

Process Value (PV) read from the Solo

LED Status read from the Solo

Y301 to Y308 represent the LED status of the Solo
Bit 0 – Y301 – ALM3
Bit 1 – Y302 – ALM2
Bit 2 – Y303 – F degrees
Bit 3 – Y304 – C degrees
Bit 4 – Y305 – ALM1
Bit 5 – Y306 – OUT1
Bit 6 – Y307 – OUT2
Bit 7 – Y308 – AT (Auto Tuning)
