[NEQ]는 Not Equal Instruction 의 약어다
좀 간단한 명령어 인것 같군요.
Source A [N7:9]의 데이터 와
Source B 데이터 정수 900 비교 해서 같으면 출력 Coil On
The NEQ instruction is used to test whether two values are not equal. If source A and source B
are not equal, the instruction is logically true. If the two values are equal, the intruction is
logically false.
The symbol for the not equal command is illustrated above. The NEQ command is placed on
the left side of the rung to determine if a rung will be true or false for an output command. There
are two parameters to enter Source A and Source B:
Source A - must be a Address.
Source B - can be either a program constant or an address. Negative integers are stored in
two's complemntary form.
