C-More EA9 HMI Series Headless RHMI to Solo and Click PLC Controllers




The cmore EA9 HMI has an event manager that can be used to trigger actions based on various events.

We will be adding a Click PLC to our headless RHMI cmore EA9 program that we created last time to communicate to the solo process temperature controller. The Solo will be connected via RS485 using the Modbus RTU protocol. Using the Modbus TCP protocol we will connect the Click PLC to the Ethernet port. Using the event manager we will be writing the set value (SV) and present value (PV) of the solo process temperature controller to the Click PLC. We will also allow the Click PLC to write the SV into the solo. This is in addition to the writing of the set value via remote apps and the solo itself. Let’s get started. Continue Reading!

C-More EA9 HMI Series Headless RHMI to Solo Process Temperature Controller




The cmore EA9 HMI can connect to the Solo process temperature controller using the built-in RS485 serial communication port. This will connect up to 32 solo units back to the HMI for display and control.

We will be setting up our headless RHMI cmore EA9 to communicate to the Solo process temperature controller. Using the information that we have discussed previously, we will set up data logging, file transfer protocol (FTP), bitmaps, etc.

We will also set up an object library of the Solo 4896. This will consist of a bitmap, numeric display, numeric edit, indication lights and up and down increment. The system will then be controlled using the remote applications discussed last time. Let’s get started. Continue Reading!

Click PLC Logging Data with Time and Date Stamp




The Click PLC can perform indirect addressing. This means that I can ask for information to be moved to and from locations in the PLC using a pointer that will indicate the address.

Stephen Covey in The 7 Habits of Highly Effective People said: “Begin With the End in Mind.” This is especially true when looking at storing or logging data within the programmable logic controller. (PLC) It is important to fully define what you want to accomplish with your program.

In our Click PLC example, we want to take a series of consecutive memory locations (DS1 to DS10) and store them in memory areas DS100 to DS4100 each minute. We will be able to store 400 entries (400 minutes) in our storage area. Every entry will include the real-time clock (RTC) of the Click. This will show the date and time of each entry. Let’s get started! Keep on Reading!

C-More EA9 HMI Series Headless RHMI Remote Control




Remote access will allow for viewing or controlling the C-More EA9 HMI series. We can use any windows based machine or use the C-More remote HMI App from Apple iTunes store, Google Play or Amazon App Store for mobile devices. This software is available free of charge.

Setting up the EA9 series for remote access and control is done through the C-More programming software to the HMI. We will be downloading the Windows application from the c-more panel. This is done through the web browser of your computer. We will also look at the c-more remote HMI app from Google play. Let’s get started. Continue Reading!

Wiring 3 Wire DC NPN and PNP Sensors




I recently received a question on PNP and NPN sensors. They wanted an explanation of what a sink is and how to wire one. Confusion over the Normally Open and Normally Closed function of the sensor is also a common question. Several diagrams will show a resistor attached to the blue wire and a load across the others, what does it all mean?

It is quite confusing sometimes the language we use for these devices. Sometimes it is the way we talk about the sensor and sometimes about the device we are connecting. (PLC)
We will break it down and go over the wiring to a PLC input. Let’s get started. Continue Reading!

C-More EA9 HMI Series Headless RHMI Setup Screens

The C-more headless EA9-RHMI is programmed using the C-more Programming Software, EA9-PGMSW. The developed project is transferred from the PC to the HMI by either a USB or an Ethernet connection between the two. Previously we used the Ethernet connection to establish communication.

We will be using the USB connection to establish communication, save the program and review the setup screens of the Headless C-more.

Troubleshooting of the USB connection and windows driver will also be discussed. Let’s get started. Continue Reading!

Stride MQTT Gateway to Adafruit IO

MQTT protocol is used for machine to machine (M2M), internet of things (IoT) communication. This publish/subscribe messaging is used where limited device resources are available or network bandwidth is low. The MQTT protocol provides small size, low power usage, minimized data packets, and efficient distribution of information to one or many receivers.

The Stride MQTT Gateway is an industrial 4.0 hardware component (IIoT – Industrial Internet of Things) that provides isolation and can easily interface with existing Modbus RTU and Modbus TCP communication protocols.

We will again be connecting a Stride MQTT Gateway to a Solo process temperature controller with Modbus RTU(RS485). The MQTT Gateway will communicate to the Adafruit IO Broker. The broker can display, log and allow us to control the data. This is done in an easily configured interface. Let’s get started. Continue Reading!

C-More EA9 HMI Series Headless RHMI Panel

The C-More EA9 HMI Panel now comes in a headless version. (EA9-RHMI) All of the great features that are already built into the EA9 are available with the new headless model. This unit can be mounted within the cabinet and you can decide how to display the information.

This user-friendly, time-saving software platform allows your system data to now be shown to the operators in new ways thanks to the C-More headless HMI panel. Capabilities like data logging, FTP (File Transfer Protocol), secure email, remote HMI and data sharing can now be added to existing PLC hardware.

We will be unboxing this EA9-RHMI unit. Once power is supplied to the unit we will then establish communication and save the program. Let’s get started. Continue Reading!

We will be connecting a Stride MQTT Gateway to a Click PLC (Ethernet) via Modbus TCP. Previously we connected the Solo process temperature controller with Modbus RTU(RS485). We will leave this connection in place and add the Click PLC. The MQTT Gateway will communicate with HiveMQ Broker. MQTTBox Client will then read and write to the Click PLC and Solo process temperature controller. Let’s get started. Continue Reading!

C-More EA9 HMI Series Panel Sending Email

The C-More EA9 HMI Panel through the Ethernet port can send secure email messages. These mail messages with attachments can be sent through a specified mail server.

We will be sending an email using a Gmail account with authentication. This will also include an attached logged data file. We will also discuss how the C-More HMI can send a text (SMS) message. Let’s get started. Continue Reading!
