Board Installation of PROFIBUS-DP
Set the node address of the device using the address configuration switch of the
PROFIBUS-DP board. Set network termination ON or OFF with the terminator switch.
(1) Set the node address of the PROFIBUS-DP board using the address configuration
 NOTE
(2) Turn network termination ON or OFF using the terminator switch.

Prepare the cable for PROFIBUS-DP sold in the market as a communication cable.
 NOTE
Install terminating resistors at both ends of the network.
A terminating resistor is installed in the PROFIBUS-DP board. Turn the terminating
resistor ON or OFF using the terminator switch on the front panel.

switch. Make sure that the node address is different from the other devices in the
network. Switch on the "×10" side for tens digit address configuration. Switch
on the "×1" side for units digit address configuration.
Generally, a node address from 0 to 125 is available for the PROFIBUS-DP device,
however, this Controller supports node addresses from 0 to 99.
Generally, node addresses are
recommended to be configured
as shown in the table.
