CS/CJ, CVM1, and CV-series PCs: Writing Data with CMND(194)
• Command Words
Word Contents
(Hex)
S 28 01 EXPLICIT MESSAGE SEND command code = 2801 (Hex)
S+1 02 1C Slave node number = 02 (Hex)
READ BYTE DATA command service code = 1C (Hex)
S+2 00 2F Class ID = 002F (Hex)
S+3 00 01 Instance ID = 0001 (Hex) specifies data area
S+4 0A 00 Starting read address = 000A (Hex) specifies IR 010
Address L = 0A (Hex); Address H = 00 (Hex)
S+5 28 00 Number of bytes = 28 (Hex) specifies 40 bytes
(The rightmost byte of S+5 is not used.)
• Response Words
(The results are stored as follows.)
Word Contents
(Hex)
D 28 01 EXPLICIT MESSAGE SEND command code = 2801 (Hex)
D+1 00 00 Normal completion code = 0000 (Hex)
D+2 00 2A Number of bytes received = 2A (Hex) indicates 42 bytes
(This is the number of bytes from D+3 to the end.)
D+3 02 9C Slave's node number = 02 (Hex)
READ BYTE DATA response service code = 9C (Hex)
D+4 HH LL These words contain the data read from slave words IR 010 to
IR 029. When the READ BYTE DATA command is executed
to :
from an OMRON Master, the bytes are stored in the same order
D+23 HH LL
(HH LL) in which they were stored in the Slave.
• Control Words
Word Contents
(Hex)
C 00 0B Number of bytes of command data beginning with word S =
0B (Hex) specifies 11 bytes
C+1 00 30 Number of bytes of response data beginning with word D =
30 (Hex) specifies 48 bytes
C+2 00 01 Destination network address = 01 (Hex)
C+3 3F FE Master's node number = 3F (Hex) specifies 63
Master's unit address = FE (Hex) specifies the local Unit
C+4 00 00 Response required
Transmission port number = 00 (Hex) specifies 0
Number of retries = 00 (Hex) specifies 0
C+5 00 64 Response monitoring time = 64 (Hex) specifies 10.0 seconds
This example shows the instruction operands and results when 20 words of
data are written through a Master mounted in a CS/CJ, CVM1, or CV-series
PC to words IR 010 to IR 029 in a Slave.
