Productivity 1000 Series PLC Contact and Coil Instructions

The Productivity Suite Software consists of more than 82 instructions divided into 13 categories for the PLC. Contacts and Coils are two of the categories of instructions. Contact instructions include NO / NC, NO Edge / NC Edge and Compare. Coil instructions include Out, Set, Reset, OR Out, Flasher, Debounce, Timed, Toggle, Program End and No Operation.

We will be looking at these instructions in the Productivity 1000 series PLC. Adding to our favorite instructions helps us to organize the instructions. We will also look at organizing your favorite instructions. 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.

Productivity 1000 Series 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.

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.

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 System Hardware

The Productivity 1000 series of programmable logic controllers has a slim stackable super compact design. This is sometimes also referred to as a shoebox PLC because of the shape and way in which expansion modules are added. This new Productivity 1000 series PLC is the latest in the Productivity series of controllers that have hit the market.

Productivity 1000 (Stackable Micro PLC)
Productivity 2000 (Micro Modular Programmable Controller)
Productivity 3000 (Modular Programmable Controller)

These three series currently make up the Productivity Series form Automation Direct.

The Productivity 1000 series PLC provides the following features for your automation control panel.
– 50MB user memory – Can handle very complex applications easily.
– 4 built-in communication ports – Easy connectivity to your network. This would include your PC, HMI, Networks, etc.
– Data logging up to 32 GB on a microSD card
– Add up to 8 IP modules to communicate to your field sensors. This will give you a total of 128 discrete IO points or 32 analog IO channels.
– Free Software and 30 days of free training with every CPU from Automation Direct.
– Interactive PLC Configuration Tool
– Tag Names
– Auto discovery IO – Physical I/O tags will be generated based on each module’s position in the base. You can also reconfigure the setup and assign new tags manually.
– I/O Modules have QR codes under the wiring cover. This can be scanned so you can have the latest specifications / wiring diagrams for the module.
– Limitless PID – Auto tuning – Individual or Cascade Mode – etc
– Web Server and Mobile Access
– Advanced Software instruction set

We will be looking at allot of these features of this powerful controller. Let’s start by looking at the hardware. 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.

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!
