*1 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.
 Command
• The following table lists the commands and subcommands. (When the inverter receives a command other than listed in
the following table, it returns an error code (HC059).)

information (when failed) is stored in hexadecimal. (Unit: byte)
The command processing result is stored. The value "0" is stored for normal completion. The

When the command is completed normally, data such as the read data corresponding to the
Little
command is stored.
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.
The footer is used for the TCP/IP and UDP protocols. The footer is added by the external

Description
The inverter reads the value in bit devices (with
consecutive device numbers) in 1-bit units.
The inverter reads the value in bit devices (with
consecutive device numbers) in 16-bit units.
The inverter reads the value in word devices (with
consecutive device numbers) in 1-word units.
The inverter writes the value to bit devices (with
consecutive device numbers) in 1-bit units.
The inverter writes the value to bit devices (with
consecutive device numbers) in 16-bit units.
The inverter writes the value to word devices (with
consecutive device numbers) in 1-word units.
The inverter reads the value in the devices with the
specified numbers. The devices with non-consecutive
numbers can be specified. The value is read from the
word devices in 1-word or 2-word units.
The inverter writes the value to the bit devices with the
specified device numbers (each set of 1 bits has a
device number). The devices with non-consecutive
numbers can be specified.
The inverter writes the value to the bit devices with the
specified device numbers (each set of 16 bits has a
device number). The devices with non-consecutive
numbers can be specified.
The inverter writes the value to the word devices with
the specified device numbers (each word or each set of
two words has a device number). The devices with non-
consecutive numbers can be specified.
Remote Run is performed to the inverter.
Remote Stop is performed to the inverter.
The model name and model code of the inverter are
read.
