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
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.
Service unit such as PG/PC
Operation panel such as HMI
(2) Turn network termination ON or OFF using the terminator switch.
Wiring (PROFIBUS-DP)
PROFIBUS-DP connector is standard D-sub 9 pins connector.
Terminal name for each pin
Prepare the cable for PROFIBUS-DP sold in the market as a communication cable.
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.
