<p>A processor for PLC (programmable logic controller) that executes logic operation. The processor (1) comprises means (2) for executing logical operation, jump inhibit means (3), jump condition determining means (4) for determining whether the execution of a next instruction be omitted and jumped depending upon the result of logical operation, and jump instruction execution means (5) which executes the jump instruction. When the jump condition determining means (4) determines that the next instruction needs not be executed and should be jumped, the jump instruction execution means executes the jump without executing unnecessary instructions so that the operation is carried out at high speeds.</p> |
