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 num-
ber 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 address lm.6. 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 address lm.1. 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 address lm.0. 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 address lm.2. 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.
