Settings For Profibus - HBM ClipX Bedienungsanleitung

Settings for PROFIBUS

In your browser, specify the address of the ClipX on the PROFIBUS. The factory setting
is 126 (invalid address). The bit rate is automatically detected by the ClipX. Carry out the
further configuration of the fieldbus using your PROFIBUS configuration tool.
After configuring the ClipX, you can download the resultant GSD file and the DPV1 list to
DOWNLOAD GSD
the PC:
setting, you are prompted to select a folder, or the file is saved to your Download folder.
The names you set for the various signals are applied in the GSD file.
The minimum cycle time (Min_Slave_Intervall) is 0.6 ms. If the PROFIBUS
controller does not take this value from the GSD file, you must set it manu-
ally.
You can download a default PROFIBUS GSD file via your web browser's Device Storage
menu or from the HBM website: https://www.hbm.com/ClipX.
DPV0 (Cyclical data content)
During the cyclic transmission of measured or calculated values, 5 bytes are transmit-
ted on PROFIBUS (and only here): 4 bytes for the measured value (FLOAT) and 1 byte
(USINT) for the status of this value. This applies to the following measured values: Elec-
trical value (Field value), Gross, Net, Minimum value, Maximum value, Peak-to-Peak,
Captured value 1/2, ClipX bus value 1 ... 6, Calculated value 1 ... 6, External Eth. value 1/2
and Analog Output. If the status byte equals 0, the respective value is valid; if the status
byte is not equal to 0, the value is invalid.
The External FB value 1/2 is the exception, it is only transmitted with 4 bytes (without
status).

DPV1 (Acyclic data content)
The DPV1 objects are addressed by way of Slot and Index. Whether a module has been
configured in a ClipX PROFIBUS slot (and if so, which one) is irrelevant. There are, how-
ever, PROFIBUS configuration tools that only send DPV1 requests when there is actually
a module in the scanned slot. In this case you must fill up the empty slots.
CiA404-compliant objects are located in slot 4.
