A50 04 Serial Port 1 (EX)
Communication Error
Flag ON when a communication error has
occurred at the Serial Port 1 (EX). ON: Error
OFF: Normal
Retained Cleared Refreshed
when error
occurs
05 Serial Port 1 (EX)
Send Ready Flag
(No-protocol Mode) ON when the Serial Port 1 (EX) is able
to send data in no-protocol mode. ON: Able-to-send
OFF: Unable-to-send
Retained Cleared Written after
transmission.
06 Serial Port 1 (EX)
Reception Completed
Flag (No-protocol
Mode) ON when the Serial Port 1 (EX) has
completed the reception in no-protocol
mode.
• When the number of bytes was
specified: ON when the specified
number of bytes is received.
• When the end code was specified:
ON when the end code is received or
256 bytes are received.
ON: Reception
completed
OFF: Reception not
completed
Retained Cleared Written after
transmission.
07 Serial Port 1 (EX)
Reception Overflow
Flag (No-protocol
Mode) • ON when a data overflow occurred
during reception through the Serial
Port 1 (EX) in no-protocol mode.
• When the number of bytes was
specified: ON when more data is
received after the reception was
completed but before RXD was exe-
cuted.
• When the end code was specified:
ON when more data is received after
the end code was received but
before RXD was executed.
• ON when 257 bytes are received
before the end code.
ON: Overflow
OFF: No overflow
Retained Cleared Written after
transmission.
A51 00 to
07 Serial Port 1(EX)
Polled Unit
Communications Flags The corresponding bit will be ON when
the Serial Port 1(EX) is communicating
with Serial PLC Link mode.
Bits 0 to 7 correspond to Units 0 to 7.
ON: Communicating
OFF: Not
communicating
Retained Cleared Refreshed
when there is a
normal
response to
the token.
00 to
15 Serial Port 1(EX)
Reception Counter
(No-protocol mode
only) Indicates (in binary) the number of
bytes of data received when the serial
port 1(EX) is in no-protocol mode. Retained Cleared Refreshed
when data is
received.
A52 --- Pulse
Output 2
PV Lower four
digits Contain the number of pulses output
from the corresponding pulse output
port.
PV range:
8 000 0000 to 7FFF FFFF
hex (-2,147,4 83 ,64 8 to 2,147,4 83 ,647)
When pulses are being output in the
CW direction, the PV is incremented by
1 for each pulse.
When pulses are being output in the
CCW direction, the PV is decremented
by 1 for each pulse.
PV after overflow: 7FFF FFFF hex
PV after underflow:
8 000 0000 hex
Note If the coordinate system is rela-
tive coordinates (undefined ori-
gin), the PV will be cleared to 0
when a pulse output starts, i.e.
when a pulse output instruction
(SPED, ACC, PLS2, ITPL or
IFEED) is executed.
Cleared Cleared • Refreshed

instruction is
executed
