If you wanted to redirect the memory movement to a different address you would just update the address value stored in D300. Using pointers allows you to not have to modify your MOV instruction, for example, if you want to direct a value to a series of different places in different conditions. Software: CX-Programmer Course Level: Beginners Language: English (India) You need our Youtube membership to get access to a few videos in the course. You can also use the * modifier to do and this will treat the 0100 stored in D300 as a BCD value - in other words, instead of pointing to D256 it will point to D100! The Omron PLC programming training course is designed for engineers and technicians using the CX-programmer software. If D300 = then a MOV instruction to will move data to D256 (hex 0100). Note that the symbol is used for pointers in binary/hex format. 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. If, as in the above example, D300 contained the value (=256 decimal) and if I used the instruction to D300 but I would move it to the address contained in D300 - in this case D256. Several different data conversion instructions are available in the CP1H. To be clear, #1 (the second argument) is a hexadecimal (symbol #) constant of value x0001. 2007 7:53 am Step 2: Define one of the Modbus Poll Registration Key If you. If I used the instruction I would move the hex data to memory location D300. and indicates values using differences in voltage CP1E PLC in Modbus TCP. In this case the symbol works like a pointer. There are no hard and fast rules about this, of course - in a lot of circumstances you can use CIO bits in place of W bits, for example, if you want to, but each has certain unique features that differentiate them and make them more suitable for certain purposes.

W (work) is used to store working memory bits (think RAM), H (hold) is used to store bits whose values must be retained if power is lost (think Hard Drive, bit data). CIO is usually used for input/output bits only. There are many memory areas of an Omron PLC.
