[3] Error Code in Response
A communication error may occur while receiving a command. In this case, this module
replies with ER (character string) and an error code.
The following error codes are provided.

FA-M3 (F3LC11-1N and F3LC11-2N)
• CPU number is out of the valid range of 1 to 4.
• Command does not exist.
• Command is not executable.
• Device name does not exist. (See Table C4.2, “Detailed Error Codes.”)
• The specification is not correct when a bit device is used in words.
• Characters other than 0 and 1 are used for bit setting. Refer to Table C4.2,
“Detailed Error Code.”
• word setting is out of the valid range of 0000 to FFFF.
• Start position exceeds the address range in Load/Save, etc.
• Specified bit count, word count, etc. exceeds the specification range (see Table
C4.2, “Detailed Error Code.”)
• The specified data count and the device parameter count, etc. do not match.
• Monitor is operated without monitor specification (BRS, WRS)
• A parameter other than those mentioned above is invalid.
• Error has occurred during communication (see Table C4.2, “Detailed Error Codes.”)
• Value of checksum differs. (Bit omitted or changed characters)
• Data received exceeds stipulated value.
• Ending character or ETX was not received.
• Timeout duration is 5 seconds.
• Sequence CPU hardware failure
• Sequence CPU command reception disabled
This failure may occur temporarily in the following cases:
• Immediately after supplying power to a sequence CPU with a 9 K-step or
longer program,
• Immediately after downloading a 9 K-step or longer program to the CPU, or
• Immediately after online editing of a 9 K-step or longer program.
Corrective action: Re-send commands.
• Insufficient sequence CPU service time
This may occur if the Ladder Diagram Programming Tool M3 is used and more than
20 READ/WRITE/DREF instructions are executed each scan.
Corrective action: • Reduce the number of READ/ WRITE/DREF instructions
executed in each scan or
• specify constant scan.
If detailed error code E1 is added, consult Table C4.2.
• CPU has detected an error during processing.
• Error has occurred in internal processing.
