Special features with DIP switch 8
As is not the case for the PROFIBUS bus terminal up to serial number 37343 (GSD file: BUER00F0.gsd,
device entry: „Typ8644“), for new devices from serial number 37344 onwards DIP switch 8 will no longer be
used for setting the stop behaviour, but for differentiating between DPV0 and DPV1 mode.
For new devices, stop behaviour is set via the parameter telegram:
DIP switch 8 - Position OFF (default setting)
The device is exchange-compatible with the predecessor up to serial number 37343 and provides the
following new functions:
• acyclical communication with e.g. RS232 modules, including in the process data channel
• various diagnosis formats
• acknowledgement of peripheral errors from the application program
• adaptation of the high-byte/low byte format to the control format on 16 and 32-channel input and output
modules.
These functions are, however, only available on new devices from serial number 37344 onwards.
When scheduling projects for the device, use the „BUER00F0.gsd“ GSD or the device entry „8644-
DPV1(DIP8=OFF) ME02“ in the S7 hardware configurator.
DIP switch 8 - Position ON
The device provides all new functions in the ON position.
Stop behaviour, which was set via DIP switch 8 in the old device, is now adjusted via parameterization.
When scheduling projects for the device, use the „BUER06BA.gsd“ GSD or the device entry „8644-
DPV1(DIP8=ON) ME02“ in the S7 hardware configurator.
