MEMO
When using PO as an output signal that indicates the target position's point number
for point movement commands (ABS-PT, INC-PT):
•When a point movement is received through a parallel I/O, the target position's
point number is output to the corresponding parallel I/O (PO0 to PO5). When
received through a serial I/O such as a CC-Link, the target position's point number
is output to the corresponding serial I/O (PO200 to PO205).
•All PO outputs are reset (OFF) when a program reset is performed.
When using PO as an output signal that indicates the corresponding point number at
the point zone output function:
• The corresponding point number for the point zone output function is output to
both the corresponding parallel I/O (PO0 to PO5) and the serial I/O (PO200 to
PO205). In the SRCP/SRCD series, however, the point number is only output to
the serial I/O.
•All PO outputs are reset (OFF) when a program reset is performed.
When using PO as an output signal that indicates the corresponding point number at
the movement point zone output function:
•The corresponding point number for the movement point zone output function is
output to both the corresponding parallel I/O (PO0 to PO5) and the serial I/O
(PO200 to PO205). In the SRCP/SRCD series, however, the point number is only
output to the serial I/O.
•Movement points are reset immediately after a controller power on, and all PO
outputs are therefore turned off at that time. Movement points are also reset if a
program reset is performed, and the movement point zone PO outputs are reset
(OFF) at that time as well.
■ Return-to-origin complete output / Zone output 0 (ORG-O / ZONE0)
This output notifies that return-to-origin operation is complete. When Zone 0
output is enabled with the Zone output selection parameter (single-axis controllers:
PRM53, dual-axis controllers: PRM24), the ORG-O output is used as the output
port of Zone 0 (ZONE0).
The ORG-O output is an output signal having the same function as bit 6 of the
output channel "n". For details on the output signal, refer to "Return-to-origin
status output (ORG-O)" in "2-7-7 Dedicated output".
The ZONE0 output is an output signal having the same function as bit 1 of the
output channel "n". For details on the output signal, refer to "Zone output (ZONE0
to ZONE3)" in "2-7-7 Dedicated output" and also to "Zone output selection"
described in the controller user's manual.
■ Servo status output / Zone output 1 (SRV-O / ZONE 1)
This is the servo status output. When Zone 1 output is enabled with the Zone output
selection parameter (single-axis controllers: PRM53, dual-axis controllers: PRM24),
the SRV-O output is used as the output port of Zone 1 (ZONE1).
The SRV-O output is an output signal having the same function as bit 0 of the output
channel "n". For details on the output signal, refer to "Servo status output (SRV-O)"
in "2-7-7 Dedicated output".
The ZONE1 output is an output signal having the same function as bit 2 of the output
channel "n". For details on the output signal, refer to "Zone output (ZONE0 to ZONE3)"
in "2-7-7 Dedicated output" and also to "Zone output selection" described in the
controller user's manual.
