BRX PLC System Hardware

The BRX series of programmable logic controllers is a stackable micro brick. This is sometimes also referred to as a shoebox PLC because of the shape and way in which expansion modules are added. This new BRX series PLC is the latest in the Do-More series of controllers that have hit the market.

Do-More H2 (Micro Modular PLC)
Do-More T1H (Stackable PLC)
BRX Series PLC (Stackable Micro Brick)

The BRX series offer built-in data logging, integrated motion control, customization communication ports and expansion capabilities. These features like other Automation Direct products are offered at a very good price point. BRX series of controllers will use the same software as the other Do-More PLCs (Do-More Designer) and is a free download. We will be looking at this full featured software that comes with a simulator later in this series.

We will be walking through allot of the features of this powerful controller. Let’s start by looking at the hardware. Continue Reading!

ACC Automation 2016 Review

Acc Automation

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!

Horner XL4 Report Generator

The Horner APG XL4 all in one controller has a feature to generate text reports. These reports can consist of text and data from memory locations in the controller. Reports can be printed using a serial interface printer through any of the serial ports of the unit or can be saved on the removable micro SD media card attached to the device. We will be taking our process mixing tank and generating a report that will show when the batch started, filled the tank and when the batch was finished emptying. This report will be saved on the removable micro SD media card attached to the unit. Continue Reading!

Horner XL4 Recipe Instruction

The Horner APG XL4 all in one controller has recipe instructions. Recipes allow you to send or update multiple registers in your program from the removable micro SD memory card. Each recipe can have 250 ingredients and 1024 products. The number of recipes will be limited to the size of the removable memory card. We will be looking at applying recipes to our process mixer application. Editing, Save, Load and View instructions for the recipe will be discussed. Continue Reading!

Horner XL4 Math Instructions

Math instructions in the Horner APG XL4 OCS all-in-one controller are broken down into Basic Math Operations and Advanced Math Operations.
Basic Math Operations include the following:
Math Equation Element, Add, Subtract, Multiply, Divide, Modulo, Square Root, Absolute Value
Advanced Math Operations include the following:
Power of X, Base 10 Logarithm, Power of e, Natural Logarithm, Sine, Cosine, Tangent, Inverse Sine, Inverse Cosine, Inverse Tangent, Convert to Radians, Convert to Degrees, Scale

We will be looking at the expression and scaling math functions. Continue Reading!

Horner XL4 Compare and Move Instructions

Compare and move instructions in the Horner XL4 OCS all-in-one controller can be very powerful. We will be looking at how to use these instructions. Combining these two instructions to build a sequencer, we will apply this to an application example. Our application will be a simple traffic light. The HMI screen will show a picture of each of the lights. Continue Reading!

The 7 Essential Parts of a PLC System

When I was in school PLC’s were just in their infancy. We were taught that the PLC consisted of the central processing unit (CPU), analog and digital inputs and outputs. Everything was programmed with dedicated handheld devices and/or software devices on specialized hardware. We now have modern PLC systems that are capable of so much more. Let’s look at how we can now break up these modern PLC system into the seven essential components.

CPU
Inputs and Outputs (I/O)
Analog I/O
Specialty I/O
Programming Tools
HMI
Networking Continue Reading…

Horner XL4 Cscape Software Setup

The Horner XL4 OCS all-in-one controller is programmed using Csape. Cscape (Control Station Central Application Programming Environment) We will now setup the Cscape software so we can easily communicate and program our controller. Continue Reading!

Horner XL4 System Hardware

The Horner XL4 OCS is an All-in-one controller. This means that this modern unit combines a logic controller, operator interface, I/O and networking all into one package. This OCS (Operator Control Station) family was first released in 1998. New features to the line-up have been added over the years. Today the OCS family has a very competitive advantage as you will soon see.
Programming is done with a single programming software package. Cscape (Control Station Central Application Programming Environment) is designed to be easy to use and maintain.

This series on the Horner XL4 all-in-one controller (PLC) will go step by step through learning how to use this innovative unit. Continue Reading…

Click PLC Shift Register Instruction

Allot of times when programming a PLC you need to track what has previously happened. Shift registers allow you to do just that. The Click PLC has a shift register in the instruction set. We will discuss the shift register and look at an example.  Keep on Reading!
