ESCRIPTION
FIELD BUS NODE PROFIBUS DPV1
As part of the expansion of field bus node Profibus DPV1 (article no. 00148837) new functions have been
added and suggestions taken into account:
• DPV1 for category 1and category 2 masters
• acyclical communication with e. g. RS232 modules, including in the process data channel
• Parameterization of E/A modules
• Failsafe values
• 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
Special features of the DIP 8 switches
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.
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 the
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.
New functions
DIP switch settings on PROFIBUS bus terminal from serial number 37344 onwards
DIP switch assignment
DIP switch Relevance
1 to 7 PROFIBUS address in binary display ( 0 to 127 in decimal display)
Switch 1 establishes the least significant bit (LSB) (2 0 )
Switch 7 establishes the highest significant bit (HSB) (2 6 )
8 Inline station operating mode;
ON: New mode with DPV1support, security values and parameterization;
OFF: Compatible mode (to PROFIBUS bus terminal up to serial number 37343)
9 and 10 When using an LWL connector, both switches are on ON in order take account of the
increased current requirement of the LWL connector. There is then no voltage shut-off
to the interface power supply.
