Practical Tips and Techniques
An array is a storage area for a group of common data type tags. They usually have some relationship to each other and need to be manipulated as a group. Last time we defined an array and use this in an indirect addressing program. It sequenced bits in an output card indirectly. In this second … Read more
An array is a storage area for a group of common data type tags. They usually have some relationship with each other and need to be manipulated as a group. We can use arrays for motion control, recipe management, sequencing (indirect addressing), math, etc. The Productivity 1000 Series PLC uses arrays that are programmed using … Read more
Data handling instructions are used to perform movement and manipulations of the memory in the programmable logic controller. The Productivity 1000 Series PLC has fifteen different data handling instructions that can be used in a wide variety of applications. In this second part we will be looking at the following instructions: Lookup Table (LKUP) – … Read more
Data handling instructions are used to perform movement and manipulations of the memory in the programmable logic controller. The Productivity 1000 Series PLC has fifteen different data handling instructions that can be used in a wide variety of applications. In this first part we will be looking at the following instructions: Absolute Encoder (ABSE) – … Read more
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). The automation system that you implement may involve these instructions. As a system integrator, you … Read more
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 … Read more
