Structured Text in Allen Bradley RSLogix5000

[neilm]

Hello Everyone,

I had a doubt in reading expressions written in structured text in format c := a and b. Where a is a DINT and b is a constant value. What is the logical interpretation of it?

Thank you.

This is a bitwise ‘and’ operation. Each bit of ‘a’ is ANDed with the corresponding bits of ‘b’ and the result is stored in ‘c’.

Got it! Thank you Jeremy.
