Name Label Operation
Error Flag ER • ON if the file memory type specified in C does not exist.
• ON if the settings in C are not within the specified range.
• ON if the filename specified in D2 does not satisfy the required conditions.
• ON if the File Memory Operation Flag was ON.
• ON if a constant was not specified for C (only for CS-series CS1 CPU Units prior to V1).
• ON if data specified for D1 is out of range (all CPU Units except for CS-series CS1 CPU Units prior to
V1).
• ON if an illegal area is specified for S.
• With the CS1D CPU Units: ON if the active and standby CPU Units could not be synchronized.
• OFF in all other cases.
Name Address Operation
Memory Card Type A343.00 to A343.02 Contains a binary number indicating the type of Memory Card, if any, that is installed.
(0: None, 4: Flash ROM)
Memory Card Format Error Flag A343.07 ON when the Memory Card is not formatted or a formatting error has occurred.
File Write Error Flag A343.08 ON when an error occurred when writing to the file.
File Write Impossible Flag A343.09 ON when the data could not be written because the file was write-protected or there
was insufficient free memory.
No File Flag A343.11 ON when the specified directory does not exist when writing a file.
File Memory Operation Flag A343.13 ON for any of the following:
The CPU Unit has sent a FINS command to itself using CMND(490).
FREAD(700) or FWRIT(701) are being executed.
The program is being overwritten using a control bit in memory.
A simple backup operation is being performed.
Accessing File Flag A343.14 ON when file data is actually being accessed.
Memory Card Detected Flag A343.15 ON when a Memory Card has been detected.
0 (OFF) when a Memory Card cannot be detected.
EM File Memory Format Error Flag A343.06 ON when there is a format error in the starting bank of EM file memory.
Number of Data to Transfer A346 to A347 The contents of these words indicate the status of data file transfers.
When an FWRIT(701) instruction is executed, the number of words or fields to be
transferred is written to these words. The value is decremented by 1 as each word is
transferred.
A346 contains the rightmost 16 bits and A347 contains the leftmost 16 bits of the 32-bit
binary value.
