This instruction will subtract two 16 bit words from each other and set the carry flag if the value is less than 0. The BCD with carry instruction will add zero to the result word. When the carry flag is set we use a BCD add with carry instruction. In the following example, we are using the BCD add without carry instruction. This instruction will add two 16 bit words together and set the carry flag if the value is over 9999. The word can be a signed (negative numbers) or unsigned value, single or double word. These instructions deal with binary or BCD addition, subtraction, multiplication, and division. The following example will demonstrate the use of the carry flag. If the result is 9999 (0000 вЂ“ 1) then the carry flag will be set. This instruction will decrement the selected word by 1. We will use it to execute another BCD increment on the next register In the following example you will see the use of the carry flag. If the result is 0000 (9999 + 1) then the carry flag will be set. This instruction will increment the selected word by 1. These instructions are useful for indirect addressing. In total, we have 8 different variations of these instructions. It can also be a single 16-bit address or a double 32-bit long address. The instruction can use a binary or BCD number. Incrementing and decrementing instructions are used to add 1 or subtract 1 from a specified word. Increment / Decrement Instructions вЂ“ Omron CP1H Math

We will now go over some of the math instructions in the Omron CP1H.

Please refer to the programming manual or help file in CX-Programmer for different variations of the instructions that you want to use. This will trigger the instruction to happen only once. ++B(594) when used will be scanned and executed every cycle of the PLC that the input condition is when used will be executed when the input condition turns from off to on. LetвЂ™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 вЂ“ 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.
