CS/CJ, CVM1, and CV-series PCs: Writing Data with CMND(194)
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.
For details on explicit messages, refer to the
CS/CJ Series DeviceNet Units
Operation Manual
(W380) for CS/CJ-series PCs, and refer to the
DeviceNet
Operation Manual
(W267) for CVM1 and CV-series PCs. For details on
CMND(194), refer to the
CS Series Programmable Controllers Operation
Manual
(W339) for CS-series PCs, and refer to the
