Meaning
If a write to EEPROM fails for the error log, it
is assumed the EEPROM is beyond its use-
ful life and this flag is turned ON. With a
Serial Communications Unit, the ERC indica-
tor will also light. Although this has no effect
on communications and other functions,
replace the Board or Unit promptly for ease
of maintenance.
This flag is turned ON if an error is detected
in the protocol data SUM check when the
power is turned ON. With a Serial Communi-
cations Board, the ERR/ALM indicator on the
CPU Unit will also flash and the RDY indica-
tor will flash at 1-second intervals. A42409
(Board only) of the Auxiliary Area will also
turn ON.
With a Serial Communications Unit, the RDY
and ERC indicator will flash.
This error may occur if the communications
connector becomes disconnected or the
PLC power is turned OFF during protocol
data transfer. Use the CX-Protocol to trans-
fer of the protocol data again.
This flag is turned ON if a Setup error occurs
in the allocated DM Area, After changing the
Setup, turn ON the power again, restart the
Board/Unit, restart the port, or execute the
STUP(237) instruction.
ON when the port can operate correctly.
OFF when protocol macro data is being
transferred.
This flag indicates the receive status of a
remote Unit during SEND when Xon/Xoff
flow control or RS/CS flow control is set in
the transmission control parameters. When
Xon/Xoff flow control is set, the reception
buffer is cleared when the sequence starts,
so the status area is set to remote Unit
receive wait (0).
1: Remote Unit receive busy
(Reception is disabled because the
reception buffer is full.)
0: Remote Unit receive wait (Reception is
enabled.)
