11.4.7.1. Constructing One DeviceNet Network
This section describes how to construct a DeviceNet network configuration through an application example. Before
constructing a DeviceNet network, users should understand the control requirement of the network; plan the data for
exchange in advance such as maximum communication distance, slaves, total data length for exchange as well as the
requreiment for response time during data exchange.
The information above will determine whether the constructed network is reasonable and able to meet the demand. Even
it will directly affect the future maintenance and convenience of network capacity expansion and upgrade.
Connection Figure
Note: Both of the ends of the DeviceNet Bus cable must connect one 121Ω terminal resistor respectively. The terminal
resistor is connected between CAN_H and CAN_L.
Modules Setting
Prepare two AS PLCs and two AS01DNET-A modules for constructing one DeviceNet network. The setups for two
AS01DNET-A modules are shown in the follwing table.
DeviceNet network module Node address Baud rate
AS01DNET-A (Master)
0 500kbps
AS01DNET-A (Slave)
1 500kbps
