BRX Do-More PLC Peerlink Ethernet Network


The BRX Do-More PLC Peerlink Ethernet communication network is one of the easiest networks to set up and run. Peerlink is a shared programmable logic controller (PLC) common memory area within a local network. Do-More central processing units (CPUs) or DirectLogic PLC systems using ECOM100 modules can read the entire area and write to their programmed area if selected.

The network uses TCP/IP broadcast packets to publish the blocks of data PEERLINK (PL) memory to all of the devices attached. This broadcast will share the data network to the local domain only. Each member can optionally send data to the other members of the data-sharing network by electing to “publish” one or more blocks of PEERLINK (PL) memory.
This can sound confusing at first, but it is the simplest network to set up. You can have your Peerlink network up and running in a matter of minutes. We will be setting up and demonstrating the Peerlink network using a BRX BX-DM1E-18ED13 and the Do-More Simulator. Let’s get started. Continue Reading!

Productivity Suite PLC Simulator Software Free Download


The productivity suite software now contains a plc simulator. The software is a free download and is available from automation direct. This software will now allow you to test or troubleshoot your program without the physical hardware present. The entire family of controllers can use the simulator. P1000, P2000, and P3000 emulation can happen on the following parts of the productivity series hardware:
– P1000 CPU’s and local I/O stack, P2000 and P3000 CPU’s and local bases
– All basic I/O modules, both analog and digital
– Modbus TCP Server/Client connections on external Ethernet port
Productivity Suite PLC Simulator Software Free Download
The simulation mode is available on the Productivity Suite version 3.8.x.x or higher. We will be discussing the PAC (Programmable Automation Controller) PLC Simulator. Testing this simulator will be done using our first program (Start-Stop Circuit) and the PID instruction in our Productivity 1000 series. We will also be connecting to physical hardware after using our simulator to test the program. Let’s get started. Keep on Reading!

Productivity 1000 PLC Documenting the Program

Last time we created our first program and transferred this to our connected Productivity 1000 Series PLC. This was programmed with our computer running the Productivity Suite Software. One of the most important aspects of programming the PLC is to document. This will aid you and your team in programming, troubleshooting, and modifying the automation control system. Your documentation should read like a book so information can be quickly obtained when required. Time spent on the documentation will be priceless when you go to read your program in 1, 3 or 10 years from now. The Productivity Suite software provides several different methods for documenting your program.
Productivity 1000 Series PLC Documenting the Program
Tag Names and Details, Task Names and Descriptions, Rung Comments and Instruction comments are the ways that we will be looking at documenting our program.

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.
Suppanel Android HMI to Click PLC (Modbus TCP)
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.

BRX PLC AdvancedHMI Communication – Modbus TCP

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 BRX Series PLC.

Our sample BRX PLC program will display a digital panel meter and a gauge of a value in the PLC. Stop and start momentary pushbuttons on the HMI will allow this number to increase or stop. An indication will turn green when the number is increasing and red when it has stopped. The AdvancedHMI package will communicate Modbus TCP over Ethernet to the BRX PLC. We will be able to monitor our process via the AdvancedHMI window. Lets get started. Watch on YouTube…

BRX PLC Data Logging

Data logging does not have to be complicated anymore. The BRX Series PLC can log your specific data up to 32 Gigabits on a Micro SD Card. It will store your data for future data analysis in a CSV (Comma Separated Value) Txt file based on time and/or event.
This is all accomplished with just one instruction in the BRX PLC. Excel is just one program that you can import and analysis this CSV Text file.
Do-More Designer has a Browse PLC File Systems window that will allow you to copy, create and delete the files from the connected computer. This will save you from going to each controller, removing and copying the files on the Micro SD Card.
We will be looking at the data logging instruction in the BRX Series PLC and how to retrieve and view this information. Let’s get started. Continue Reading!

ACC Automation 2017 Review

ACC Automation


We would like to take a few minutes and reflect on the past, current and future of ACC Automation. 2017 has been our best year yet thanks to you. Your questions, comments and suggestions have helped us to build the site that you see today.
Thank you. Continue Reading!

BRX PLC Serial Communication – Modbus RTU to Solo Process Temperature Controller

Serial communication instructions will allow you to send and receive serial data to an external device. The communication method that you setup can be ASCII or numeric (binary). ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer or display.

Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC.

The BRX Series PLC will allow you to use instructions such as STREAMIN and STREAMOUT to send and receive data from devices mentioned above. They are usually a one to one device and do not have a protocol.
A protocol is like a language used to communicate to different devices connected together. Modbus serial communication (Modbus RTU) is a standard protocol used in many industrial automation devices. The BRX Series PLC has a MRX (Modbus Network Read) and MWX (Modbus Network Write) instructions.

We will demonstrate these instructions by communicating Modbus RTU to a Solo Temperature Controller. (RS485) Our example will read the current process (PV) value and write the set point value (SV) in the controller. Let’s get started. Continue Reading!

BRX PLC Drum Instruction

Drum instructions are great tools when you have a simple sequence of events that need to occur at a set time interval or as a result of an event. They mimic an electromagnetically drum sequencer. The BRX Series PLC has a drum in the instruction set.
Have you ever seen the mechanisms of a music box? Ok so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is on the drum. So in the PLC you can have a drum driven by an event, (input from a limit switch or button), or by time.
We will discuss the drum instruction and look at an example of controlling traffic lights with a cross walk signal. Continue Reading!

BRX PLC Shifting Instructions

PLC shifting instructions will move bits in memory areas a fixed amount when instructed. Bits are on/off, 1 or 0 and are usually associated together to form a memory location. The memory location can be used for numbers or positions.
PLC BITS NUMBERS AND POSITION is a post that will review the different methods that the PLC will interpret the information in memory
We will be looking at the shifting (moving) of the bits within the memory location in several different ways. ROTL rotate left, ROTR rotate right, Math shift left operator, Math shift right operator, Math unsigned shift right operator and SR shift register are some of the instructions in our BRX PLC that will shift bits.
Let’s look at some samples of each of the above mentioned instructions. Continue Reading!
