This header is for TCP/IP and UDP/IP. Add the header on the external device
side before sending a message.
TCP/IP is supported by servo amplifiers with software version A3 or later.
2 bytes Big At a request: 5000h
At a response: D000h
6 bytes Big At a request: 5400h + Serial number + 0000h
At a response: D400h + Serial number + 0000h
1 bytes Specify the network No. of the access destination. Specify it in hexadecimal.
Store a value of a request message.
1 bytes Specify the station number of the access destination. Specify it in
hexadecimal.
Store a value of a request message.
2 bytes Little 03FFh (fixed)
1 bytes 00h (fixed)
2 bytes Little Specify the data length from the monitoring timer to the request data in
hexadecimal.
Example) For 24 bytes: 1800h
2 bytes Little Set the waiting time until the servo amplifier that had received a request
message from an external device completes read or write processing.
When the servo amplifier cannot return a response message within the
waiting time, the response message will be discarded.
Variable Little Specify the command, sub command, and data that indicate the request
content.
2 bytes Little Refer to section 2.4.3.
2 bytes Little Refer to section 2.4.3.
2 bytes Little The data length from the end code to the response data (at normal
completion) or error information (at abnormal completion) is stored in
hexadecimal. (Unit: byte)
2 bytes Little The command processing result is stored. 0 is stored at normal completion. An
error code of the servo amplifier is stored at abnormal completion.
Refer to section 2.4.5 for the error code.
Variable Little The read data and others corresponding to the command are stored at normal
completion.
9 bytes The network No. (responding station) (1 byte), station No. (responding station)
(1 byte), request destination module I/O No. (2 bytes), and request destination
multi-drop station No. (1 byte) of a station that responds an error are stored at
abnormal completion. Numbers that do not correspond to the content of the
request message may be stored because the information of the station that
responds an error is stored at abnormal completion. The command (2 bytes)
and sub command (2 bytes) in which an error occurs are also stored.
This footer is for TCP/IP and UDP/IP. Add the footer on the external device
side before sending a message.
TCP/IP is supported by servo amplifiers with software version A3 or later.
0000h: Waiting until the processing is completed
0001h to FFFFh (1 to 65535): Waiting time (Unit: 0.25 s)
