The Stride Field I/O Modules are simple and compact. They provide an economical means to connect inputs and outputs to an Ethernet Modbus TCP communication network. Every module operates as a standalone Modbus TCP server and can be configured via a built-in web server.
We will be looking at the following two Stride Remote IO Modules:
– STRIDE discrete combo module, Input: 8-point, 12-24 VDC, sinking, Output: 4-point, relay, (4) Form C (SPDT) relays, 2A/point, (1) Ethernet (RJ45) port(s), Modbus TCP server.
– STRIDE analog input module, 4-channel, current/voltage, 16-bit, isolated, input current signal range(s) of +/- 20 mA, input voltage signal range(s) of +/- 10 VDC, (1) Ethernet (RJ45) port(s), Modbus TCP server, external 20-30 VDC required.
We will be unboxing both of these units. Powering and then setting them up (configuring) via the webserver. Let’s get started. Continue Reading!
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!

It is a good time to be in the automation business. Technologies are merging and communicating like never before. What was impossible is now possible for the industrial plant floor. We are looking forward to the New Year and new possibilities for implementing your control solution.
Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you.
2019 has been our best year yet thanks to you. Keep on Reading!
Stack lights are usually modular stackable components that provide a visually illuminated and audible indication for machines, systems, and processes. They are usually located on top of equipment to provide this notification to personnel in the area.
Stack lights are also known as signal tower lights, indicator lights, warning lights, industrial signal lights, tower lights, and light towers.
We will be connecting a Patlite NPS-402-RYGB Super Slim stack light to our Click PLC.
These stack lights come in preassembled units in the most popular combinations of colours with ABS resin main bodies that offer superior impact and heat resistance; double-insulated construction enhances durability and safety. Interchangeable light modules require no rewiring. Let’s get started. Continue Reading!
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.

Recently I was asked to demonstrate communication between a BRX PLC and Click PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. It works on a Master / Slave configuration. You can have only one master per network on Modbus RTU (Remote Terminal Unit). A maximum of 32 devices (Nodes) on the network can communicate to the master. A review of the Modbus RTU protocol (RTU frames) can be seen at the following URL.
Using the BRX PLC as a Master, we will be communicating to the Click PLC (Slave). Our example will read 10 registers from the Click PLC and write 10 registers from the BRX PLC. Let’s get started! Continue Reading!
We would like to take a few minutes and reflect on the past, current and future of ACC Automation. You have help us succeed in our best year yet.
Starting off we learned how to:
Create a PLC with HMI Training and Learning Environment Free – Utilized the Do-More Designer Software and the AdvancedHMI Software we communicated Modbus TCP to the Do-More simulator. This was all done on one computer without any need for additional hardware. The best thing about this was that the investment was only time learning the packages. Continue Reading!
Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is that the software is free. We will look at using AdvancedHMI with the Click PLC. Our sample Click PLC program will read the present value (PV) and the indicating lights on our Solo Process Temperature Controller. It will then write the set value (SV) to the Solo. This communication will be done using Modbus RTU protocol over a RS485 serial port on the Click. The AdvancedHMI package will communicate Modbus TCP over Ethernet to the Click PLC. We will be able to monitor our PV and set our SV on the Solo via the AdvancedHMI window. Keep on Reading!
Receive and Send instructions will allow you to send and receive serial data to an external device. The communication method that you setup can be ASCII or Modbus. ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer. Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. We will demonstrate the Send and Receive instruction by communicating Modbus to a Solo Temperature Controller. Our example will read the current process (PV) value and write the set point value (SV) in the controller. Keep on Reading!
The program control instructions will allow us to specify what parts of the logic get solved and when this happens. This will control how the PLC will scan and solve your logic in your program. Keep on Reading!
