Common instructions
Common instructions include instructions that:
- Monitor and control the status bits.
- Change the flow of logic.
Instruction | Description |
|---|---|
Supports a Boolean operation between a connection line state and a Boolean variable. | |
Supports a Boolean operation between a connection line state and the falling edge of a Boolean variable. | |
Supports a Boolean operation between a connection line state and the Boolean negation of a Boolean variable. | |
Supports a Boolean operation between a connection line state and the rising edge of a Boolean variable. | |
Supports a Boolean output of a connection line Boolean state. | |
Supports a Boolean output of a connection line Boolean state. | |
Enables a Boolean output of a connection line Boolean state. | |
Enables a Boolean output according to the Boolean negation of a connection line state. | |
Enables a Boolean output according to the Boolean negation of a connection line state. | |
Enables Boolean output of a connection line Boolean state. | |
LBL and JMP skip portions of ladder logic. JMP controls the execution of a diagram and LBL is the target for JMP. | |
Returns are outputs that represent a conditional end of a ladder diagram (LD) program. |
