This example shows the instruction operands and results when 20 words of
data are written through a Master mounted in a CS1, CVM1, or CV-series PC
to words IR 010 to IR 029 in a Slave.

EXPLICIT MESSAGE SEND command code = 2801 (Hex)
Slave node number = 02 (Hex)
READ BYTE DATA command service code = 1C (Hex)
Class ID = 002F (Hex)
Instance ID = 0001 (Hex) specifies data area
Starting read address = 000A (Hex) specifies IR 010
Address L = 0A (Hex); Address H = 00 (Hex)
Number of bytes = 28 (Hex) specifies 40 bytes
(The rightmost byte of S+5 is not used.)
EXPLICIT MESSAGE SEND command code = 2801 (Hex)
Normal completion code = 0000 (Hex)
Number of bytes received = 2A (Hex) indicates 42 bytes
(This is the number of bytes from D+3 to the end.)
Slave's node number = 02 (Hex)
READ BYTE DATA response service code = 9C (Hex)
These words contain the data read from slave words IR 010 to
IR 029. When the READ BYTE DATA command is executed
:
from an OMRON Master, the bytes are stored in the same order
(HH LL) in which they were stored in the Slave.
Number of bytes of command data beginning with word S =
0B (Hex) specifies 11 bytes
Number of bytes of response data beginning with word D =
30 (Hex) specifies 48 bytes
Destination network address = 01 (Hex)
Master's node number = 3F (Hex) specifies 63
Master's unit address = FE (Hex) specifies the local Unit
Response required
Transmission port number = 00 (Hex) specifies 0
Number of retries = 00 (Hex) specifies 0
Response monitoring time = 64 (Hex) specifies 10.0 seconds
