Logicbus I-7550E Converters Interfaces Profibus
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: Profibus converteri-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.
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
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.
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.
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.
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:\profibus\converter\i-7550e\manual\i-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.
Application example of PROFIBUS to Ethernet TCP server
In this example the I-7550E acts as a TCP Client device. When PROFIBUS Master
station sends data, I-7550E module can transfer the data to specific TCP
server. If I7550E module receives the data from TCP server, it can send the
data to the input data area of PROFIBUS master station.
Hardware configuration
PROFIBUS connection Here we recommend users to use the standard PROFIBUS cable and connector (DB9 male). It is only needed to use D-type connector via PROFIBUS cable to connect PROFIBUS Master station and I-7550E module. PROFIBUS Master station and I-7550E module belong to terminal equipments in this example, thus 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
I-7550E can be set by DIP switch. The DIP switch can be seen by open the
cover, as shown in the below. The range of DIP switch is 0~126, here we set
I7550E module’s DIP switch to 1.

Establish connection with I-7550E
Before establish the connection between DP-Master and I-7550E, users should obey the following steps first.
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.

(Directory: –> CD:\profibus\converter\i-7550e\gsd\) 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
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 modules：32 modules
- System setting module：20 Bytes output , 20 Bytes input
- Output module：1~16 Bytes, 32Bytes, 64Bytes, 64 Words
- Input module：1~16 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:
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
¾ Set the network configuration of the I-7550E
- Open MiniOS7 utility and press “F12” to find IP address of I-7550E.
- 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.
- 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).
- Press “Save to Device” to save settings to EEPROM of I-7550E.
- 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.
- Press “Save to Device” to save settings to EEPROM of I-7550E and restart I-7550E.
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:
\PROFIBUS\Converter\I-7550e\utilities\TCPserver”).The TCPserver setting is
shown in the below.
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.
Send ”profibus” string in PROFIBUS output data area
At the meantime, TCPserver will response 10 Bytes data “0x00~0x09”. PROFIBUS master can receive data in the input data area, as shown in the below:
Receive 10Bytes data(0x00~0x09) in PROFIBUS input data area
