6.12.3 Sequence control relay

Input/output

Operand

Data type

Boolean

SCR instruction is good at dealing with repetitive

operations.

SCR: load the SCR section, you can use the SET

instruction.

SCRT: Jump to another SCR segment and close the

current SCR segment.

SCRE: The instruction signs the end of SCR segment.

Example:
