Math instructions are used to perform mathematical calculations. The Productivity 1000 Series PLC has math instructions that can be used in a wide variety of applications. We will be looking at the Data Statistics (DATA) and the Math Editor (MATH).
Your automation system that you implement may involve these instructions. As a system integrator you will require the use of these instructions in your commissioned programs.
Let’s get started with the Productivity 1000 Series PLC Math Instructions. Continue Reading!
Cofaso 7 is a computer aided engineering (CAE) solution software package. Its special system technology with direct access to applicable logic for each schematic allows industry design and documentation for all solutions. Electrical engineering project tasks will become easier with Cofaso 7. This parameter controlled system is available in 13 languages and supports all the common windows versions.
Cofaso 7 meets all global evaluation standards. It offers complete authoring and editing of electrical engineering documents. Some of the features in the package include: Cross-references, wiring lists, terminal diagrams, terminal connection diagrams, interconnect diagrams, PLC cross references, mounting plate design and more.
Cofaso provides flexible editing features:
XML, EXF and graphics interfaces such as DXF guarantee data interchange with other CAx systems and ensure the integration of cofaso into the unified production chain. Article data of any kind be imported or incorporated. An intelligent article number search function provides an additional aid to locating components used in the diagram.
We will be creating a PLC drawing with 5 outputs. These outputs will be connected to another box with the same reference numbers. We will also show the automated connection list. Anytime a reference name is changed all document items will change for that reference. Let’s get started. Continue Reading!
We will now put our first program into the C-More Micro HMI Panel using the C-More Micro programming software. The Do-More Designer Simulator will be used with a modified Start Stop Jog Circuit so we can use our HMI screen to control the output as well as the inputs on the PLC.
The PLC logic for our circuit can be found on our post: How to Make a Start / Stop / Jog Circuit in a PLC. The YouTube video can be seen here.
Our C-More Micro HMI Panel will be communicating to the PLC simulator via Ethernet with the Modbus TCP protocol. Let’s get started. Continue Reading!
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!
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 Instructions – Video)
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!
The C-more Micro HMI Panels from Automation Direct include a series of built in Systems Setup Screens. They are split into three categories; Information, Setting and Test Menu.
Information – Under the information menu we will find the panel model number, available memory and usage, the protocol being used by the panel and the version information of the firmware and boot loader.
Setting – Under the setting menu we can adjust the brightness of the display, enable or disable the internal beeper, calibrate the touch panel, clear the user memory, reset the unit to factory defaults and set the loading screen hourglass icon delay or disable the display.
Test Menu – The test menu includes communication tests of the serial ports (loop back test), communication test to the PLC, test operation of the panel’s beeper, and test of the touch panel surface.
We will be reviewing these system screens of the C-More Micro HMI Panel. Let’s get started. Continue Reading!
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!
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!
The C-more Micro Programming Software is a free download from Automation Direct. This is similar to the more powerful C-more Touch Panel programming software. This free HMI (Human Machine Interface) software has features designed to reduce your configuration time. Simply drag and drop the objects from the object bar onto the screen construction area. Configure your PLC tags and click on the objects you want to use. A built in simulator will allow you to review your work on the computer before downloading the project.
We will be installing the C-more Micro Programming Software onto our PC (computer). Updating the software is also very easily done. See video below.
Let’s get started. Continue Reading!
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!
