Bit A34311 is turned ON when the specified file is not on the installed card or
no card is installed.
Bit A34312 is turned ON when the Memory Card is being written to from the
program (FILW(181)).
Bit A34313 is turned ON when an instruction affecting Memory Card files
(FILR(180), FILW(181), FILP(182), or FLSP(183)) is being executed.
Bit A34314 is turned ON when the Memory Card is being accessed.
Bit A34315 is turned ON when the Memory Card is write-protected by the
write-protect switch on the card.
Word A346 contains the number of words left to transfer to or from the
Memory Card (FILW(181) or FILR(180)). When either instruction is first
executed, the number of words in the file is placed in word A346 and as data
is transferred, the number of words transferred is subtracted from this num-
ber.
The number of words to transfer is recorded in 4-digit BCD.

3-6-21 Error Code
When an error or alarm occurs, the error code is written to A400. If two errors
occur simultaneously, the more serious error, with a higher error code, is re-
corded. Refer to
Section 8 Error Processing
for details on error codes.
3-6-22 FALS Flag
Bit A40106 is turned ON when the SEVERE ALARM FAILURE instruction
(FALS(007)) is executed. The FAL number is written to word A400.
3-6-23 SFC Fatal Error Flag and Error Code
Bit A40107 is turned ON if an error that stops operation occurs while the SFC
program is being executed. The SFC Fatal Error Code is written in BCD to word
A414. Refer to
Section 8 Error Processing
for details on the error codes.
3-6-24 Cycle Time Too Long Flag
Bit A40108 is turned ON if the cycle time exceeds the cycle time monitoring
time (i.e., the maximum cycle time) set in the PC Setup.
3-6-25 Program Error Flag
Bit A40109 is turned ON if there is a program syntax error (including no
END(001) instruction).
3-6-26 I/O Setting Error Flag
Bit A40110 is turned ON if the I/O designation of a slot has changed, e.g., an
Input Unit has been installed in an Output Unit’s slot, or vice versa.
3-6-27 Too Many I/O Points Flag
Bit A40111 is turned ON if the total number of I/O points being used exceeds the
maximum for the PC. The total number of I/O points being used on CPU and Ex-
