IMPORTANT
The station address specifies the node address of the
controller on the DH-485 network.
To optimize network performance, assign station
addresses in sequential order.
Assign initiators, such as workstations, the lowest
station address numbers to minimize the time
required to initialize the network.
The maximum station address specifies the
maximum node address of all the devices on the
DH-485 network.
IMPORTANT
To optimize network performance, make sure:
• the maximum station address is the highest node
number being used on the network.
• that all the devices on the same DH-485 network
have the same selection for the maximum station
address.
