CP2E CPU Unit Software User’s Manual(W614)
The data and FINS commands can be transmitted between the CP2E N -type CPU Unit and other
devices using the CMND, SEND or RECV instuction.
Setting the network address and the node address of the instrction in the CP2E N -type CPU Unit
ladder program, it is possible to send the data and FINS commands to another device, or receive data
from another device.
c
CP2E N -type CPU Unit requests the data to be transmitted from
d
CP2E N -type CPU Unit
(node address 3 ) in the local network and receives the data.
When W0.00 and A202.7 (the Communications Port Enabled Flag for port 07) are ON, 20 words are
read from D100 to D119 of
d
CP2E N -type (node address 3 ), transmitted to
c
CP2E N -type
and stored in D200 to D219 using the RECV instruction.
