Note Error clear codes are 1-word (2-byte) data, so the above codes are
specified with the low byte first. The low to high bytes for the above
codes are set as high to low bytes in I/O memory, when setting the
codes as data for operand S of CMND(490). For example, to specify
battery error 00F7 Hex, specify the error code as F7 Hex followed by
00 Hex, as shown in the following diagram.
The settings for operand S and following words for CMND(490) are shown in
the following diagram.
No. of bytes received (response): The number of bytes received from the
destination node address (remote node) is returned in hexadecimal.
Destination node address (response): The node address of the CS/CJ-
series DeviceNet Unit from which the response was sent is returned in hexa-
decimal.
00F7 Battery error
0200 to 020F CS/CJ-series CPU Bus Unit error (last 2 digits are binary code for
the Unit No.)
For parity errors generated when data transferred between CS/CJ-
series CPU Bus Unit and CPU Unit
For watchdog timer errors in CS/CJ-series CPU Bus Unit
0400 to 040F CPU Bus settings error (last 2 digits are binary code for the Unit
No.)
System error (FAL): FAL instruction executed
4101 to 42FF
