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 I- 7550E module receives the data from TCP server, it can send the data to the input data area of PROFIBUS master station.

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 I- 7550E module’s DIP switch to 1.
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:\profibus\converter\i-7550e\gsd\) 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.

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. I - 7 5 5 0 E...

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.

5. I-7550E module communication test This demo uses TCP server program on the PC to communicate with I-7550E. Users from companion CDROM(PATH:“CD: \PROFIBUS\Converter\I-7550e\utilities\TCPserver”).The TCPserver setting is shown in the below. TCPserver operate procedure PROFIBUS input/output test --Send data to TCPserver and get response data from TCPserver.
