[Function] Set the output type in the output field to be used when a PATH or PSPL command is
executed.
When a PATH or PSPL command is executed, the output will operate as follows in
accordance with the setting of the POTP command.
(1) POTP [Operand 1] = 0 (ON upon completion of operation)
The output port or flag will turn ON upon completion of operation.
(2) POTP [Operand 1] = 1 (Increment and output on approaching each position; ON upon
completion of operation for the last position)
During PATH or PSPL operation, the output port number or flag number specified in the
output field will be incremented and turned ON when each specified position approaches.
At the last position, however, the output will turn ON upon completion of operation. This
setting provides a rough guide for output in sequence control.
(Note 1) The default value of POTP, before it is set, is “0.”
(Note 2) If POTP = 1 and there is no valid data at the specified position, the output number will be
incremented but the output will not turn ON. (The output number will be incremented
regardless of the size of position numbers specified in operands 1 and 2 in a PATH or PSPL
command.)
[Example] POTP 1
PATH 1 5 300 Turn ON output port Nos. 300 through 304 sequentially
each time a specified position approaches during a
pass movement from position Nos. 1 through 5, starting
from the first position.
