A-1 Instruction Functions
The CP2E CPU Units support the following instructions.
Refer to the CP1E/CP2E CPU Unit Instructions Reference Manual (Cat. No. W483) for details.
A-1-1 Sequence Input Instructions
Instruction Mnemonic Variations Symbol/Operand Function
LOAD LD @/%/!/!@/!% Indicates a logical start and creates an ON/OFF execution condi-
tion based on the ON/OFF status of the specified operand bit.
LOAD NOT LD NOT @/%/!/!@/!% Indicates a logical start and creates an ON/OFF execution condi-
tion based on the reverse of the ON/OFF status of the specified
operand bit.
AND AND @/%/!/!@/!% Symbol Takes a logical AND of the status of the specified operand bit and
the current execution condition.
AND NOT AND NOT @/%/!/!@/!% Symbol Reverses the status of the specified operand bit and takes a logi-
cal AND with the current execution condition.
OR OR @/%/!/!@/!% Takes a logical OR of the ON/OFF status of the specified operand
bit and the current execution condition.
OR NOT OR NOT @/%/!/!@/!% Reverses the status of the specified bit and takes a logical OR
with the current execution condition.
