I-7550E Converters Interfaces Profibus
I-7550E Quick Start
1. Introduction
The I-7550E is a module that allows data transfer between a
PROFIBUS Master station and a TCP server. This manual provides
basic settings and operating instructions for the I-7550E. For more
detailed information, please refer to the user manual found on the
ICP DAS companion CD-ROM (Path:
CD:profibusconverteri-7550emanuali-7550e user manual.pdf).
In this example, we will be using the CIF50-PB PROFIBUS Master
card from Hilscher, and the configuration and communication will be
done by the program SyCon provided by Hilscher.
Application example of PROFIBUS to Ethernet TCP server
In this example, the I-7550E acts as a TCP Client device. When
the PROFIBUS Master station sends data, the I-7550E module can
transfer the data to a specific TCP server. If the I-7550E module
receives data from the TCP server, it can send the data to the
input data area of the PROFIBUS Master station.
2. Hardware configuration
The I-7550E requires power connection, RS-232 connection,
Ethernet connection, and PROFIBUS connection.
PROFIBUS connection
We recommend using a standard PROFIBUS cable and connector (DB9
male) to connect the PROFIBUS Master station and I-7550E module.
The D-type connector via PROFIBUS cable is only needed to connect
both devices. The PROFIBUS Master station and I-7550E module belong
to terminal equipments in this example, so we need to enable the
terminator resistor in the D-type connector.
Address setting
The I-7550E is a slave device of PROFIBUS DP protocol. The
station address of the I-7550E can be set by DIP switch. The DIP
switch can be seen by opening the cover. The range of the DIP
switch is 0~126, and we set the I7550E module’s DIP switch to
1.
LED status indicator
| LED | Status | Description |
|---|---|---|
| PWR | Flash | Power supply is OK. The firmware has loaded. |
| PWR | Off | Power supply has failed. |
| ERR | Flash | When the I-7550E has a diagnostic message, it will flash slowly (flash once about 220ms). The connection is an error with PROFIBUS Master device or PROFIBUS system configuration is not correct. |
| ERR | On | PROFIBUS system configuration is correct. |
| RUN | On | Data exchange mode. It is normal operation. |
| RUN | Off | I-7550E module is not in data exchange mode. |
3. Establish connection with I-7550E
Before establishing the connection between DP-Master and
I-7550E, users should follow these steps:
- Load the electronic device description file (GSD file) of the
I-7550E into the DP-Master. - Set the parameters and configurations.
- Change your DP-Master from offline state to operate state. The
I-7550E will be initialized. If there is no error, the I-7550E
proceeds into data exchange state. If there is any error, the
I-7550E will return to wait for parameterization.
4. Software configuration
GSD file
Please copy the GSD file (IPDS0EB9.gsd) and the bitmap file
(i_7550E.bmp) to your computer and load the GSD file into your
DP-Master before establishing a connection with the I-7550E.

1. Introduction
This manual introduces the I-7550E’s basic setting and operating quickly, the user can refer to the user manual in the ICP DAS companion CD-ROM (Path: “CD:profibusconverteri-7550emanuali-7550e user manual.pdf”). This manual helps users to understand about the I-7550E module and application. In the following examples the CIF50-PB PROFIBUS Master card from Hilscher is used. The configuration and communication is done by the program “SyCon” provided by Hilscher.

3. Establish connection with I-7550E
Before establish the connection between DP-Master and I-7550E, users should obey the following steps first.
1. First, users must load the electronic device description file (GSD file) of the I-7550E into the DP-Master.
2. And then set the parameters and configurations.
3. Finally change your DP-master from offline state to operate state. The I-7550E will be initialized. If there is no error occurs, I-7550E proceeds into data exchange state. At the meantime, if there is any error occurs, I-7550E will return to wait for parameterization.
4. Software configuration
GSD file
Please copy the GSD file (IPDS0EB9.gsd) and the bitmap file (i_7550E. bmp,
ICP7550E.bmp) from the CD of the I-7550E module into the Profibus
configuration tool.
File->CopyGSD
(Directory: –> CD:profibusconverteri-7550egsd) ¾ the example of how to load GSD file
Here, we use the hilscher CIF50-PB PROFIBUS communication interface to
show how to load I-7550E’s GSD file step by step.
Step 1: Click insert slave button in the PROFIBUS configuration tool.
Step 2: Choose I-7550E device and click Add button.

Step 3: Set address of I-7550E and then click OK button.
Step 4: Finish adding I-7550E in the DP-master interface.
¾ Set the modules of the I-7550E
The user needs to set the number and size of the I/O modules in the PROFIBUS configuration tool. The settings of the modules are described below.
Max. I/O modules32 modules
System setting module20 Bytes output , 20 Bytes input
Output module1~16 Bytes, 32Bytes, 64Bytes, 64 Words
Input module1~16 Bytes, 32Bytes, 64Bytes, 64 Words
In any case, “System setting module” must be selected first. In this example,
we want to have 10 Bytes Input and 10 Byte Output, so we configure a
“System setting module”, a “10 Byte In” module and a “10 Byte Out” module
as below:
Double click I-7550-E’s icon to enter Slave configuration dialog
Configure module and click OK button
When the user finishes the configuration and saves setting in the PROFIBUS Master station successfully, the ‘RUN’ LED indicator of I-7550E is turned on. That shows the I-7550E working in the data exchange mode.

Click <Online->Download> to download the setting into PROFIBUS Master station ¾ Set the network configuration of the I-7550E
1. Open MiniOS7 utility and press “F12” to find IP address of I-7550E. 2. Open web browser (ex. IE). Enter IP address of the I-7550E in the
Address field and press “Enter” to connect to I-7550E, and then enter default password (“icpdas”) to login to I-7550E in Login page. 3. Click “Server IP Setting” to set the network configuration of the I7550E (please refer to user manual section 5.3). The network configuration of the I-7550E must have the same domain and different IP with the PC (ex: PC’s IP=192.168.253.1, MASK=255.255.0.0;and I-7550E’s IP=192.168.253.2, MASK=255.255.0.0). 4. Press “Save to Device” to save settings to EEPROM of I-7550E. 5. Click “Client IP setting” to set the information of TCP server (please refer to user manual section 5.3). In this case, we setup C_IP9(192.168.253.1) and enable it. 6. Press “Save to Device” to save settings to EEPROM of I-7550E and restart I-7550E.

5. I-7550E module communication test
This demo uses TCP server program on the PC to communicate with I-7550E. Users can get it from the ICP DAS companion CDROM(PATH:”CD: PROFIBUSConverterI-7550eutilitiesTCPserver”).The TCPserver setting is shown in the below.
TCPserver operate procedure
¾ PROFIBUS input/output test
–Send data to TCPserver and get response data from TCPserver.
The user needs to set the value of “System setting module” from Byte 0~ Byte 10, and set output data (“profibus”) from the Byte 20~ Byte 27. After finishing the setting, the user needs to set the value of Byte 1 from 0 to 1 to trigger the data output function.
