Parameters
Ethernet communication (FR-A800-E)
FR-A800
5 - 775
The serial No. is given by the external device for message recognition. If a request message with a
serial No. is sent, the same serial No. will also be added on the response message. The serial No. is
used when multiple request messages are sent from an external device to the same inverter.
Monitoring timer
2 bytes
Little
Set the waiting time until the inverter completes reading/writing after
receiving a request message from the external device.
When the inverter does not return the response message within the
waiting time, the response message will be discarded.
앫
H0000: Unlimited (until the execution is completed)
앫
H0001 to HFFFF (1 to 65535): Waiting time (Unit: 0.25 s)
Recommended settings:
Request data
Variable
Little
Specify the command, subcommand, and data that indicate the
requested operation. (Refer to page 5-776.)
Response data
length
2 bytes
Little
The data length from the end code to the response data (when
completed) or error information (when failed) is stored in hexadecimal.
(Unit: byte)
End code
2 bytes
Little
The command processing result is stored. The value "0" is stored for
normal completion. The error code of the access destination (refer to
page 5-785) is stored for failed completion.
Response data
Variable
Little
When the command is completed normally, data such as the read data
corresponding to the command is stored.
Error information
9 bytes
—
The network No. (responding station) (1 byte), station No. (responding
station) (1 byte), destination unit I/O No. (2 bytes), and destination
multidrop station No. (1 byte) of the stations which respond errors are
stored for failed completion. Numbers different from those in the
request message may be stored because the information on the station
with error response is stored. The command (2 bytes) and the
subcommand (2 bytes) being issued when an error occurred are also
stored.
Footer
—
—
The footer is used for the TCP/IP and UDP/IP protocols. The footer is
added by the external device before transmission.
