Productivity 1000 Series PLC Modbus TCP Ethernet Communication

The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Ethernet protocols like Modbus TCP can be utilized with the RJ45 port on this PLC. Modbus TCP is an open (published) protocol that uses the Server (Master) / Client (Slave) architecture. It’s a very common protocol used in industrial automation controls.

We will be using the RJ45 (Ethernet) port to communicate to a Click PLC. Modbus TCP will be the protocol used on this Ethernet communication media. The Productivity 1000 PLC will be the server and the Click PLC will be the client. We will be creating a network between the two PLC units. A heartbeat will be used so if communications is lost, the server (slave) will know. The throughput time will be timed by using a small program in the Click PLC. You will soon see how the Productivity Series of PLC’s is the best way to handle communication to other devices. Let’s get started. Continue Reading!

C-More Micro HMI Object Text

The C-More Micro HMI Panel software uses virtual components called Objects. Five different text objects are available for your industrial human machine interface. (HMI) Static text will place words on your HMI page. Lookup text will display a message corresponding to a value in a tag register. Dynamic text will display the ASCII (American Standard Code for Information Interchange) equivalent of the information in the tag register specified. Scroll text will display information too large to display in the area assigned. This will move the information in the display area so the entire message can be seen. Text entry will allow the user through a pop up key pad to enter ASCII characters into a tag register.

We will now look at all five of these text objects our HMI micro panel. A new page will be made to show all of the text object functions and operations. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Modbus RTU Serial Communication

The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with either the RS232 or RS485 ports on this PLC. Modbus RTU is an open (published) protocol that uses the Master / Slave architecture. It’s a very common protocol used in industrial automation controls.

We will be using the RS485 (2-wire) port to communicate to a Solo Process Temperature Controller. Modbus RTU will be the protocol used on this serial communication media. The PLC will be the master and the Solo process temperature controller will be the slave. You will soon see how the Productivity Series of PLC’s is the best way to handle communication to other devices. Let’s get started. Continue Reading!

C-More Micro HMI Object Recipe

The C-More Micro HMI Panel software uses virtual components called Objects. Recipe buttons are part of these objects. The Recipe Button Object changes the value of a tag or multiple tags. The Recipe Button Object looks and acts like a Pushbutton Object on the screen. When the Recipe Button Object is pressed, the values in the Source Data Tags are written to Destination Data Tags.

We will now look at recipes that we can use with our HMI micro panel. They include the recipe button. We will program 3 recipes into the unit that will control 4 different timers. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Web Server

The productivity series of PLCs has a built in web server. This web server function can make a non secure (HTTP) connection to the CPU. This is done with your browser. You can then view read only system tags and open, save or delete files stored on the micro SD drive.

Previously we stored data logged files on the USB (Micro SD) storage device. We will now start and configure the web server function. Look at the files from our data logger and view the system files available. Let’s get started. Continue Reading!

C-More Micro HMI Object Bitmap

The C-More Micro HMI Panel software uses virtual components called Objects. Bitmaps are part of these objects. These bitmaps are images that are made up of tiny dots called pixels. Each of these dots are actually a small square that contains one colour. Bitmaps will help you produce simple, intuitive looking human machine interfaces.

We will now look at bitmaps that we can use with our HMI micro panel. They include bitmap buttons, static bitmap, dynamic bitmaps and multi-state bitmaps. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Data Logger

The productivity series of PLCs has a built in data logger. This easy data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of a Boolean tag (event) or configured to occur at regular intervals (scheduled).

A USB storage device should be normally connected if logging data. The CPU maintains an internal 73KB buffer for temporarily logging data while no USB storage device is present. Data in the buffer will not be retained through a power cycle. Let’s get started. Continue Reading!

C-More Micro HMI Object Meters and Graphs

The C-More Micro HMI Panel software uses virtual components called Objects. Meters and Graphs are part of these objects. They can represent a range of numbers and are programmable to simulate the functions that you require on your automation project. This helps you produce simple, intuitive looking human machine interfaces.

We will now look at the meters and graphs that we can use with our HMI micro panel. They can replace the older chart recorder equipment that is still in use in some manufacturing facilities. These objects will represent the data in the PLC for the user to interpret. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Drum Sequencer Instructions

The productivity series of PLCs has a Drum and Sequencer instruction.
Drum instructions are great tools. They mimic an electromagnetically drum sequencer. Have you ever seen the mechanisms of a music box? Ok so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is on the drum. So in the PLC you can have a drum driven by an event, (input from a limit switch or button), or by time.

Sequencers are similar to the drum instruction. The sequencer output can have up to 16 Boolean, Integer or Numerical Tags per step. Drum instruction outputs are limited to the same 16 bit (Boolean) outputs. Each step in the sequencer can be defined by time or /and event and specified outputs can be set going into and out of the step.
We have done similar Drum instructions for the BRX Series PLC and the Click PLC.

We will be discussing the drum and sequencer instructions in the Productivity Series PLC. Simple examples will be done to demonstrate the power of these instructions. Let’s get started. Continue Reading!

C-More Micro HMI Object Numeric Entry

The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Several of these objects can be placed on one panel screen and you can have multiple panel screens. This helps you produce simple, intuitive looking human machine interfaces.

Continuing from last time we will now look at the numeric entries that we can use with our HMI micro panel. Let’s get started. Continue Reading!
