Different numbering systems in the programmable controller.

Do-More Designer Element Browser


The element browser in the Do-More Designer software will display valid memory locations, add documentation, and show how to cast from one memory type to another.

We will be discussing the element browser and how to take advantage of this in your Do-More program. Let’s get started. Continue Reading!

Productivity Numbering Systems and Tag Database

We will now look at the tag numbering systems used with the Productivity controller. The Productivity Suite Software allows us to use tags in the PLC. Tags are a method for assigning and referencing memory locations (numbering systems) 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 PLCs from Automation Direct. Do not overthink tags. Tags are just names that we assign to variables (numbering systems) 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!

BRX Do-More PLC Numbering Systems and Addressing

We will look at numbering systems in our BRX Do-More controller. This will include physical IO, casting, and indirect addressing. The BRX Do-More PLC like all of the PLCs in the Do-More Series use strong data typing. This means that there are fixed memory structures to work within your program. Errors will be displayed if you try to put the wrong type of value in the memory location. The data structures will automatically assist you in your automation system.
Memory can now be as flexible as you want and need. You can define and allocate all the data memory the way you want it up to specific maximums. As a system integrator, you determine what best fits your automation framework.
We will be looking at the addressing and numbering systems in the BRX Do-More Series PLC. Let’s get started. Continue Reading!

Omron CP1H Numbering Systems and Addressing

The Omron CP1H series of programmable logic controllers have a fixed input and output addressing system. Every PLC has its own way of addressing its inputs and outputs. We will be looking at how the CP1H series of controller addresses its inputs and outputs. Numbering systems used in this controller will also be looked at as well as addressing. Addressing can be direct or indirect. We will look at how this can be accomplished using examples in the CP1H controller. Continue Reading!

Horner XL4 Numbering System and Addressing

We will now look at the Horner XL4 numbering system and addressing. Data is stored in different memory-type locations called registers. The registers can be either bits or words (16bit). Multiple registers can be used together to store a 32-bit value. (Double word) This all in one controller has several additional registers to handle some of the HMI communication. Let’s look at all of the areas in the controller. Continue Reading!
