3.3 Installing RTU-PD01 and I/O Module on DIN Rail
zUse 35mm DIN rail.
zOpen the DIN rail clips on RTU-PD01 and I/O module. Insert RTU-PD01 and I/O module on the
DIN rail.
zClip up the DIN rail clips on RTU-PD01 and I/O module to fix them on the DIN rail (see the figure
below).

4.1 RUN/STOP Switch
Status Description
1. Special I/O module switches from RUN to STOP.
2. All Y points on digital output module turn OFF.
3. Modbus function switch
RUN => STOP
4. RUN LED turns off.
1. RTU-PD01 re-detects the number of digital I/O points and
specialI/O modules.
2. Special I/O module switches from STOP to RUN.
3. Enable digital I/O modules.
4. Enable Modbus function.

STOP => RUN
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
Distance (m) 1,200 1,200 1,200 1,000 400 200 100 100 100

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.
Definitions of settings:
Setup item Setting Definition
Enable
When the Modbus device is configured with
many addresses and the addresses are
consecutive, all contents in the consecutive
addresses can be read or written at a time.
Acceleration mode
Disable
When the Modbus device is configured with
many addresses, only contents in a single
address can be read or written.
