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 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 Monitoring and Testing the Program

The Productivity Suite Software provides tools for us to monitor and test our programs. Last time we used Tag Names and Details, Task Names and Descriptions, Rung Comments and Instruction comments to document our first program and transferred this to our connected Productivity 1000 Series PLC. We will be monitoring our ladder using the ladder editor window and display the information two different ways. Data View is a powerful tool to help us to test and view our program. We will be forcing the IO, toggling the IO view and graphing our tags to test our PLC logic circuit.
Let’s get started. Continue Reading!

Productivity 1000 Series PLC Establishing Communication

We will be connecting the Productivity 1000 Series PLC with our computer running the Productivity Suite Software. A micro USB and an Ethernet (RJ45) communication link will be made to our programmable logic controller.
The latest Productivity Suite software version is 3.1.0.11. This is the programming software that we will be using to create our logic for control.

Let’s get started. Continue Reading!

BRX PLC Program Control

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 using a synchronous PLC Scan. Understanding the PLC program scan will explain the synchronous and asynchronous program scanning. Ladder logic programs get solved left to right, top to bottom. The result of the rung before is available for the next rung.
Using programs, tasks and subroutines in our BRX Series PLC we can divide up our program into smaller segments. This will help when we troubleshoot the system in the field as the system integrator. Let’s look at some samples of each of the above mentioned methods. Continue Reading!

BRX PLC Online Editing and Debug Mode

Our first program for the BRX PLC involved a start stop jog circuit. We will now use the Do-More Designer Software to modify this program while the PLC is scanning the logic. This is referred to as online programming or online editing. As a system integrator, this ability can prove very useful to you in the field when commissioning your automation system.
We will also be using the special Debug Mode of the software to monitor the ladder logic status and bits on a scan by scan basis. Forcing the inputs and outputs, we will control the execution of the PLC scan. This is a great feature of the Do-More Designer software.
Here is a link explaining the logic behind our circuit.

BRX PLC Installing the Software

The BRX PLC uses the Do-More Designer software which can be downloaded free of charge and includes a simulator. The latest Do-More Designer software version is 2.0.3. This is the same software that we used in the Learn PLC Programming Fee Video Series.
The Do-More Designer software can be used to program the whole series of programmable logic controllers.

Do-More H2 (Micro Modular PLC)
Do-More T1H (Stackable PLC)
BRX Series PLC (Stackable Micro Brick)
We will be installing and reviewing the Do-More Designer software version 2.0.3. Version 2 is mainly to accommodate the new BRX Series PLC. Continue Reading!

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!

Horner XL4 Data Logging

Data logging is the ability to save and view data from the PLC in a format that we can utilize elsewhere on the network. The Horner APG XL4 has this feature in its design to periodically log registers to removable media. (Micro SD) This data is stored in .CSV (comma separated value) format which is compatible with many computer applications such as Microsoft Excel.
Horner provides one of the easiest methods that I have seen to get data logging. You can log 30 registers in a log group and have 10 separate groups. Each group has its own configurable timer that determines the automatic reading and logging of the variables (registers). The group also has a manual trigger bit that can be set to log the variables.
This all in one controller provides the easiest way to log data. We will look at how to configure and utilize this feature of the PLC. Continue Reading!
