Testing PROFIBUS

A.1 Hardware Test Device BT200 for PROFIBUS-DP

A.1.1 Possible Uses

The BT200 hardware test device for PROFIBUS-DP can be used as an installation, commissioning, and service tool. Due to its versatility, it is useful for both the installer of PROFIBUS networks as well as the experienced commissioning engineer and service engineer. An acceptance report can also be created following installation of the system.

A.1.2 Area of Application

During installation, the BT200 test device can be used to test the PROFIBUS cable. Errors made during installation are located quickly and simply, the installer does not need specific PROFIBUS experience. Even before the system is put into operation, the BT200 device can be used to test the RS-485 drivers of the PROFIBUS nodes. It is also possible to obtain a list of the accessible slaves on the bus on completion of the wiring, without having a PROFIBUS-DP master available. This means that individual bus segments can be checked in advance, reducing the commissioning times. If an error occurs, these test functions can be useful in localizing the problem and minimizing the downtimes of the system.

Note

Check the physical bus properties before commissioning with the BT200. This reduces the time required for commissioning and prevents system downtimes and sporadic bus errors.

A.1.3 Logging Functions

All the test results can be stored on the BT200. Using a point-to-point cable, the data can be transferred to a PC. The test results can be edited on the PC and printed out as a log.
