5. RUN LED turns on.
4.2 Address Setup Switch
The two rotary address setup switches, x160and x161, set up the node address of RTU-PD01 on
PROFIBUS DP network in hex form. The range for rotation is 0 ~ F.
Address Definition
H’1~ H’7D Valid PROFIBUS address
H’0 or H’7E ~ H’FF Invalid PROFIBUS address. NET LED will flash in red
color if the node address falls within this range.
0
x16
1
x16
Example: If you need to set the node address of RTU-PD01 to 26 (decimal), simply switch x161 switch
to “1” and x160to “A”. 26 (decimal) = 1A (hex) = 1x161 + Ax160.
Note:
zSwitch off the power supply before setting up the node address of RTU-PD01. Re-power the
module after the setup is completed.
zChanging the value on the switch during the operation of RTU-PD01 is invalid.
zUse slot type screwdriver to set up the switch. Be careful not to scratch the module.

5 Establishing PROFIBUS DP Network by RTU-PD01
The right-side interface on RTU-PD01 is connectable to DVP-Slim series special I/O modules and
digital I/O modules. The RS-485 port is connectable to standard Modbus devices. See the figure below
for the connection of Slim series I/O modules and Modbus devices and into the PROFIBUS DP
network.
6 Transmission Distance and Baud Rate
The baud rate range for PROFIBUS DP is 9.6kbps ~ 12Mbps, and the length of transmission cable
varies upon the transmission speed. The transmission distance ranges from 100m to 1,200m. See the
table below for the baud rates RTU-PD01 supports and their corresponding communication distance.
Baud rate (bps) 9.6k 19.2k 93.75k 187.5k 500k 1.5M 3M 6M 12M

7 GSD File
The GSD file is a text file and can be used to identify PROFIBUS DP device (master or slave).A GSD
file usually contains the supplier’s information, baud rates supported and applicable I/O messages.
When using RTU-PD01, you have to first import the GSD file to the configuration software for
PROFIBUS DP master. After the import of the file, the configuration software for master will display
RTU-PD01 and its configuration settings. You can download the GSD file for RTU-PD01 at Delta’s
website: http://www.delta.com.tw/
8 RTU-PD01 Settings and Configurations
8.1 RTU-PD01 Settings
When you set up RTU-PD01 in the configuration software for PROFIBUS DP master, there will be
plenty of setup items for you to choose from, which adds flexibility to the manipulation of RTU-PD01.
See the figure below for RTU-PD01 settings.

8.3.1 Settings of Configuration Items for Digital I/O Modules
There are 2 types of configuration items for digital I/O modules, standard configuration and
self-defined configuration. By standard configuration, the digital I/O module is named after its
actual name, whereas it is named after the number of points by self-defined configuration. You do
not have to set up parameters in the configuration. The digital I/O can correspond to the master
directly after the configuration
8.3.2 Settings of Configuration Items for Special I/O Modules
The special I/O module is named after its actual name in the configuration. You can configure
special I/O module by standard configuration items. Detailed configuration methods will be
explained in the following paragraphs.
