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.

ab plc的meq指令是用来做什么的，怎么用？ MEQ 测试一个值是否大于或等于另一个值：测试源A的值是否大于或等于源B的值 测试一个值是否大于另一个值：测试源A的值是否大于源B的值 测试一个值是否小于或等于另一个值：

2018年7月7日 · Masked Comparison for Equal (MEQ) Use the MEQ instruction to compare data at a source address with data at a compare address. Use of this instruction allows portions of the data to be masked by a separate word.

The Mask Equal To instruction is a ladder logic rung input instruction that compares a source value to a compare value through a mask. If the adjusted source and compare values are equal the logic to the right of the instruction, or rung-condition-out, is enabled and disabled if otherwise.
