Cautions
• When not using the nest structure, clear the number of times of batch-storage before executing
ZPUSH (FNC102) instruction.
• When using the nest structure, clear the number of times of batch-storage before executing ZPUSH
(FNC102) instruction for the first time.
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When the range of points used after in ZPUSH (FNC102) instruction exceeds the corresponding
device range (error code: K6706)
• When the number of times of batch-storage stores a negative value while ZPUSH (FNC102)
instruction is executed (error code: K6707)
Instruction Description
ZPOP(FNC103)
