Parameters Destination node address (command): The node address of the CS/CJ-

hexadecimal.
Service code (command, response): IF Hex is specified for commands. For
responses, the highest bit will turn ON and 9F Hex will be returned.
Class ID (command): Always 002F Hex.
Instance ID (command): The memory area to which the data is written is
specified in hexadecimal as shown in the following table.
Address L, Address H (command): The address of the first word to which
the data is written is specified in hexadecimal as shown below.
Address L: The lower 2 digits when the first word address is displayed in 4-

Address H: The higher 2 digits when the first word address is displayed in 4-

Write data (response): The specified area and write data is returned in order
from word L (lower byte: bits 0 to 7) to word H (higher byte: bits 8 to 15).
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 that returned the response is returned in hexadecimal.
Important Points The actual address L, address H, and number of read words that can be spec-
ified depends on the mode of CPU Unit for the CS/CJ-series DeviceNet Unit
and the type of memory areas. Do not exceed the boundary of the data areas
for the PC you are using.
