Productivity 1000 Series PLC Numbering Systems and Tag Database

The Productivity Suite Software allows us to use tags in the PLC. Tags are a method for assigning and referencing memory locations within the programmable logic controller. They allow a more structured programming approach and are stored within a tag database. The tag database is stored in the memory of the Productivity Series of PLC’s from Automation Direct. Do not over think tags. Tags are just names that we assign to variables of any data type stored in the PLC memory.

We will be looking at data types available in the Productivity PLC and how to use the tag database. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Online Editing and Debug Mode

The Productivity Suite Software allows us to modify our existing program and execute the new code without stopping the scanning of the PLC. This is referred to as online editing. We change the ladder logic code and when we save it to the PLC, the current scan of the PLC is held until the new code is written into the unit. It then releases the scan and our new program start to execute. This happens in milliseconds so our process can continue to operate.
Troubleshooting the logic in our PLC sometimes can be difficult. The Productivity Suite Software has a Debug Mode. This will allow us to control the scan cycle of the PLC, decide on the rungs to execute and control the physical outputs during this time. This ability of control helps to fix errors or understand existing code in our programmable logic controller.
We will be taking our existing Start / Stop circuit from last time and add a Jog input using online editing. We will then use the debug mode in the Productivity Suite software to understand the scan and the jog function that we added.
Let’s get started. Continue Reading!

Productivity 1000 Series PLC First Program

Last time we connected the Productivity 1000 Series PLC with our computer running the Productivity Suite Software. A micro USB and an Ethernet (RJ45) communication link was made to our programmable logic controller. We will now create our first program for our Productivity 1000 Series PLC. Our program will be a simple start stop circuit for a motor. Here is a post that will explain the logic behind our program circuit.

Productivity 1000 Series PLC Installing the Software

The Productivity 1000 Series PLC uses the Productivity Suite Software. The software can be downloaded free of charge. It is the full package without restrictions or limitations.

The latest Productivity Suite software version is 3.1.0.11. Automation Direct has put 20 years of programmable controller software experience along with customer suggestions and feedback into this programming package. It has great features that we will be exploring as we program our Productivity 1000 Series PLC.
This is the same software that will program the entire Productivity Series of programmable logic controllers.

Productivity 1000 (Stackable Micro PLC)
Productivity 2000 (Micro Modular Programmable Controller)
Productivity 3000 (Modular Programmable Controller)
We will be installing and reviewing the Productivity Suite software version 3.1.0.11.
Let’s get started. Continue Reading!

BRX PLC Analog IO – System Configuration

One of the features of the BRX Series PLC is the ability to expand its capability to fit your application. This is easily done by “snap-on” modules that will fit on the side of the BRX MPU (Multi Processor Unit). As we have seen before in the BRX PLC System Configuration post we can add additional discrete inputs and outputs. Automation Direct now offers Analog Voltage and Analog Current input and output modules. These modules come as an 8 point channel unit. There is also a 4 point thermocouple input module also available. We will be configuring, scaling and programming the Analog input and output Voltage modules for our BRX PLC. Let’s get started.

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 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!

PLC Programming Example – Palletizer Drum Instructions

How many ways can you program the PLC for the same function? The answer is allot of different ways. You can have ten different programmers working on the same program and get ten different automatic control PLC programs. Sure they may have similarities but, they are all unique in their code within the PLC. As a system integrator you will see many different ways of programming the PLC. We will now look at reprogramming our palletizer example using drum instructions. (Sequencer)
Last time we applied the five steps to PLC program development to a palletizer example. We will review our steps and then change our programming code to incorporate the drum instructions. Like our original example we will allow the operator to change the layers of boxes you want on each skid. We will also add in this example a manual operation sequence to cycle thought each of the steps for troubleshooting the program.

Developing the PLC program is a process that can be clearly defined. In our series on the five steps to PLC program development we have done some similar practical examples.
PLC Programming Examples – Five Steps to PLC Program Development
– Press
Process Mixer
Shift Register (Conveyor Reject)
Paint Spraying
Delay Starting of 7 Motors
– Pick and Place
– Sorting Station (Shift Register)
Palletizer

Define the task: (1)
Watch the sequence of operation video below. This will demonstrate the pallet layer selection, running and resetting of the machine.
