Function
The time that operation stopped as a result of changing
the operating mode to PROGRAM mode is stored here
in BCD.
A518.00 to A518.07: Seconds (00 to 59)
A518.08 to A518.15: Minutes (01 to 59)
A519.00 to A519.07: Hour (00 to 23)
A519.08 to A519.15: Day of month (01 to 31)
A520.00 to A520.07: Month (01 to 12)
A520.08 to A520.15: Year (00 to 99)
If an error occurs in operation, the time of the error will
be stored. If the operating mode is then changed to
PROGRAM mode, the time that PROGRAM mode was
entered will be stored.
Contains the total time that the PLC has been on in 10-
hour units. The data is stored in binary and it is updated
every 10 hours. To reset this value, overwrite the cur-
rent value with 0000 hex.
This word is not cleared at startup, but it is cleared to
0000 when the Memory Corruption Detected Flag
(A395.11) goes ON.
Turn this bit ON to restart the RS-232C port. (Do not
use this bit when the port is operating in Peripheral Bus
Mode.)
This bit is turned OFF automatically when the restart
processing is completed.
The Online Editing Disable Bit (A527.09) is valid only
when this byte contains 5A.
To disable online editing from the CX-Programmer, set
this byte to 5A and turn ON A527.09.
(Online editing refers to changing or adding to the pro-
gram while the PLC is operating in MONITOR mode.)
Turn this bit ON to disable online editing. The setting of
this bit is valid only when A527.00 to A527.07 have
been set to 5 A.
These flags indicate what kind of error has occurred at
the RS-232C port; they are automatically turned OFF
when the RS-232C port is restarted.
(These flags are valid in Serial Gateway mode. They
are not valid in peripheral bus mode and only bit 5 is
valid in NT Link mode.)
Only the following bits are valid in Serial PLC Link
Mode.
Polling Unit:
Bit 5: ON for timeout error.
Polled Units:
Bit 3: ON for framing error.
Bit 4: ON for overrun error.
Bit 5: ON for timeout error.
These bits can be cleared by the CX-Programmer.
Set a dummy FAL/FALS number to use to simulate the
system error using FAL(006) or FALS(007).
When FAL(006) or FALS(007) is executed and the num-
ber in A529 is the same as the one specified in the
operand of the instruction, the system error given in the
operand of the instruction will be generated instead of a
user-defined error.
