Function Area Setting for DeviceNet Slave Station
The quantity of transmit/receive data for DeviceNet network communication is specified using the Function Area Setting
in
WindLDR
. The
OpenNet Controller
CPU module recognizes all functional modules, such as DeviceNet slave, L
ON-
W
ORKS
interface, and analog I/O modules, automatically at power-up and exchanges data with the DeviceNet master sta-
tion through the link registers allocated to each slave station (node).
Since these settings relate to the user program, the user program must be downloaded to the
OpenNet Controller
CPU
module after changing any of these settings.
Programming WindLDR
1.
From the
WindLDR
menu bar, select Configure > Function Area Settings. The Function Area Setting dialog box
appears.
2.
Select the Open Bus tab.
3.
Select transmit and receive data bytes for module position 1 through 7 where the DeviceNet slave module is mounted.
4.
Click the OK button and download the user program to the
OpenNet Controller
.
Configure Communication
Master Module Check Box
Check this box only when
the remote I/O master
module is used.
Quantity of Nodes Connected
When using the remote I/O mas-
ter module, specify the quantity
of nodes from 1 through 32.
Slave Station
Transmit/Receive
Data Quantity (Bytes)
When using DeviceNet
slave module or L
ON
W
ORKS
inter face module, specify
the data bytes to communi-
cate through each slave or
inter face module.
Transmit/Receive Bytes 0 to 8
(default: 8 bytes)
This value determines the data
quantity 0 through 8 bytes (64
bits) to communicate with the
DeviceNet master module.
For the example on the next
page, select 8 transmit bytes and
4 receive bytes for Module 1.
