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 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!
