Let’s look at when this instruction will execute: Instructions can have different variations. Links are provided at the end of this post.
A full explanation can be obtained by using the help menu in the CX-Programmer software or the Programming Manual for the CP1H. Several different math group instructions are available in the CP1H. Setting, Forcing, and Online Editing – Video Previously in this CP1H series, we have discussed: Examples of some of the instructions will be presented. We will be looking at some of the math instructions in the Omron CP1H PLC.
You must refer to the programming manual of the controller that you are programming for specific math instruction information. If you subscribe to our website you will get a free copy of the article on numbering systems which includes understanding floating points. The following is a post on what everybody ought to know about PLC numbering systems. Binary, BCD (Binary Coded Decimal), and floating-point single and double are examples of some numbering systems. Every controller has different methods to handle math with different numbering systems. Modern PLC controllers now come with several math instructions to expand the ability to perform math routines. Programmable logic controllers are not typically known for their math ability.
