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!

Modbus RTU Click PLC Master to BRX PLC Slave Communication

Recently I was asked to demonstrate communication between a Click PLC and BRX PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. It works on a Master / Slave configuration. You can have only one master per network on Modbus RTU (Remote Terminal Unit). A maximum of 32 devices (Nodes) on the network can communicate to the master. A review of the Modbus RTU protocol (RTU frames) can be seen at the following URL.

Using the Click PLC as a Master we will be communicating to the BRX PLC (Slave). Our example will read 10 registers from the BRX PLC and write 10 registers to the Click PLC. Let’s get started! Keep on Reading!

Click PLC AdvancedHMI Communication

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 Click PLC. Our sample Click PLC program will read the present value (PV) and the indicating lights on our Solo Process Temperature Controller. It will then write the set value (SV) to the Solo. This communication will be done using Modbus RTU protocol over a RS485 serial port on the Click. The AdvancedHMI package will communicate Modbus TCP over Ethernet to the Click PLC. We will be able to monitor our PV and set our SV on the Solo via the AdvancedHMI window.  Keep on Reading!

Click PLC Send and Receive Instructions

Receive and Send instructions will allow you to send and receive serial data to an external device. The communication method that you setup can be ASCII or Modbus. ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer. Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. We will demonstrate the Send and Receive instruction by communicating Modbus to a Solo Temperature Controller. Our example will read the current process (PV) value and write the set point value (SV) in the controller.  Keep on Reading!

Click PLC Drum Instruction

Drum instructions are great tools when you have a simple sequence of events that need to occur at a set time interval or as a result of an event. They mimic an electromechanically drum sequencer. The Click PLC has a drum in the instruction set. We will discuss the drum instruction and look at an example of controlling traffic lights.  Keep on Reading!

Click PLC Shift Register Instruction

Allot of times when programming a PLC you need to track what has previously happened. Shift registers allow you to do just that. The Click PLC has a shift register in the instruction set. We will discuss the shift register and look at an example.  Keep on Reading!
