Productivity 1000 Series PLC Counter Instructions

A majority of programmable logic controller (PLC) programs will include a counter instruction. The Productivity 1000 Series PLC has a couple of different counter instructions for your program. Under the data handling instructions we have the increment / decrement instruction (INC). We could use this with the compare contact (CMP) instruction that we discussed in our Contact and Coil Instructions (Video) to create a counter application.

The productivity suite software has a Simple Counter (SCNT) and the Counter (CNT) instructions. We will be reviewing these instructions and looking how to implement then in our ladder logic program. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Timer Instructions

Just about every programmable logic controller (PLC) program will include a timer instruction. The Productivity 1000 Series PLC has several different timer instructions for your program. We discussed the timed coil (TMC) and flasher coil (FLS) last time as part of the contacts and coil discussion. (Contact and Coil InstructionsVideo)

We will now look at using the Simple Timer (STMR) and the Timer (TMR) instructions in the productivity suite software. Let’s get started. Continue Reading!

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 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.
