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 Components

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

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.

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.
