Rslogix copy int to two bytes
data 0 (byte) width data 1 (byte) (width > 8) For converting an integer to four bytes the code would be. But UDTs and some other types take at least 4. The base types like DINT take two bytes for type info. I copy the type bytes into local memory and send them back unchanged on write. To test performance, I wrote a test program to read multiple tags from a RS Logix 5000 processor. For converting two bytes the cleanest solution is. Before the first write, I make sure I do a read.Welcome to The Automation Blog's “Flashback Friday!” Today I'm highlighting some simple code I wrote and published twelve years ago using RSLogix version 10. Flashback Friday! RSLogix 5000 ASCII Integer from Word to String.
#Rslogix copy int to two bytes how to#
How to move/copy two integer values consecutively into one DINT tag, so the first value goes into the first 16 bit of the DINT and the second - into the second part. The second argument to specifies the start index of the array of bytes.
Type returnedMethodboolchardoubleshortintlongfloatushortuintulongExampleThis example initializes an array of bytes, reverses the array if the computer architecture is little-endian (that is, the least significant byte is stored first), and then calls the method to convert four bytes in the array to an int. In addition to the method in the example, the following table lists methods in the class that convert bytes (from an array of bytes) to other built-in types. You may have to convert from bytes to a built-in data type after you read bytes off the network, for example. Contributors.In this articleThis example shows you how to use the class to convert an array of bytes to an and back to an array of bytes. How to: Convert a byte Array to an int (C# Programming Guide).
