Comparison Instructions, Data Conversion, and Analog Scaling
I'm a new user of ABB PLC's and Codesys, I'm trying to write a program using Ladder Logic, and I need to compare values. Every other PLC I've ever worked with has had Equal to, Greater than, etc instructions, are these not available with these PLC's? Same with Analog Scaling and Data conversion blocks. Are these available?

Hi Andrew
like other programming language, Codesys have the same blocks to compare values.
You can insert one new block EN in your program, then you can choose between different type of function, simple editing the name of the inserted block.
Then you choose the desired function, in the example GT
The help in line of Codesys give you the complete information about the available function
Hope this help you
