3. The instruction's 2-digit BCD FALS number (01 to 99) will be written to
SR 25300 to SR 25307.
The FALS numbers can be set arbitrarily to indicate particular conditions, but
the same number should not be used as both an FAL number and an FALS
number.
To clear an FALS error, use a Programming Device to switch the PC to PRO-
GRAM Mode, correct the cause of the error, and then clear the error.
MSG(46) is used to display a message on a Programming Device connected
to the CPM2C-S. The message, which can be up to 16 characters long, is dis-
played when the instruction's execution condition is ON.
PC operation and program execution will continue after one or more of these
errors have occurred. Although PC operation will continue, the cause of the
error should be corrected and the error cleared as soon as possible.
When one of these errors occurs, the POWER and RUN indicators will remain
lit and the ERR/ALM indicator will flash.
Meaning and appropriate response
An FAL(06) instruction has been executed in the program. Check the FAL number to
determine conditions that would cause execution, correct the cause, and clear the
error.
An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.
AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to
DM 6614) when power was turned ON. Correct the settings in PROGRAM Mode and
turn ON the power again.
AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to
DM 6644) when switching to RUN or MONITOR mode. Correct the settings in PRO-
GRAM Mode and switch to RUN or MONITOR mode again.
AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to
DM 6655) during operation. Correct the settings and clear the error.
The cycle time has exceeded 100 ms. (SR 25309 will be ON.)
This indicates that the program cycle time is longer than recommended. Reduce cycle
time if possible. (The CPM2C-S can be set so that this error won't be detected.)
If the Low Battery Detection Switch is ON and the voltage of the CPM2C-BAT01
backup battery is below the minimum level, the ERR/ALM indicator will flash and SR
25308 will be turned ON. (See page 46 for details on the Low Battery Detection
Switch.)
Replace the battery. (See 9-7 Battery Replacement for details.)
Meaning and appropriate response
If the POWER and ERC indicators are lit and the SD and RD indicators are not lit, an
error may have occurred in the CompoBus/S communications. Restart after checking
slaves and communications paths.
The POWER indicator will be lit and the COMM indicator will not be lit if this error
occurs.
AR 0804 ON: An error has occurred in communications between the RS-232C port and
peripheral device.
AR 0812 ON: An error has occurred in communications between the peripheral port
and peripheral device.
Restart after checking communications path.
