The MEQ, also known as the Masked Equals, is an instruction which will perform a similar function to the EQU (Equals) Instruction, with one key difference: a mask is applied to the compared bits. This instruction will take three operands: two which will be compared and a mask which needs to be applied.

The Masked Equals Instruction (MEQ) allows for efficient bit manipulation in PLC programming. Learn about a PLC routine that is used for recipe manipulation.

The MEQ instruction passes the Source and Compare values through a Mask and compares the results.
