CTT Counter Timer Tachometer – Tachometer Mode

The CTT series from Automation Direct are multi-function digital units. They incorporate a multi-function digital counter, timer and tachometer all within the same unit. Tachometer mode will bring in pulses that can be from a sensor, incremental encoder, etc. and convert this to a rate. Rates such as speed or frequency deal with units per time. The CTT makes converting and using these pulses easy. The tachometer mode has four different output settings; 2Lo1Lo, 2Lo1Hi, 2Hi1Lo and 2Hi1Hi.

We will be reviewing the tachometer mode of the CTT and programming a rate based on the frequency of a relay output of a PLC. Let’s get started. Continue Reading!

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!

CTT Counter Timer Tachometer – Counter Timer Mixed Modes

The CTT series from Automation Direct are multi-function digital units. They incorporate a multi-function digital counter, timer and tachometer all within the same unit. The counter timer mixed mode will operate in sixteen (16) different ways. Two different count input modes can be selected. Up or Down can be selected. We will program eight of the modes with the UP input. A number of output modes can be selected so this unit can adapt to a great number of applications.

In Timer Counter Mixed Mode, timer period setting value SV1 controls Output 1 and counter setting value SV2 controls Output 2. 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!

CTT Counter Timer Tachometer – Counter Modes

The CTT series from Automation Direct are multi-function digital units. They incorporate a multi-function digital counter, timer and tachometer all within the same unit. The counter mode will operate in five (5) different ways. Up to five different count input modes can be selected. Up, Down, UP/Command Counting Down (UdA), UP/Counting Down (UdC) and Quadrature (UdC) can be selected. We also have a number of output modes to select so this unit can adapt to a great number of applications.

We will be looking at each of the Counter modes using the Up count input on this versatile digital unit. 1-Stage, 2-Stage, Batch, Total and Dual are the modes. 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!

CTT Counter Timer Tachometer – Timer Modes

The CTT series from Automation Direct are multi-function digital units. They incorporate a multi-function digital counter, timer and tachometer all within the same unit. The timer mode will operate in twelve (12) different ways.

We will be looking at each of the timer modes on this versatile digital unit. Let’s get started. Continue Reading!
