Integration of the LES 36…/PB in the PROFIBUS
11.1
General information
The LES 36/PB and the LES 36HI/PB are designed as a PROFIBUS DP/DPV1 compatible
slave. The input/output functionality of the sensor is defined by the corresponding GSD file.
The baud rate of the data to be transmitted is max. 6MBit/s under production conditions.
For operation, the GSD file is to be appropriately modified.
The LES 36…/PB supports automatic detection of the baud rate.
Characteristics of LES 36…/PB
• Ethernet and PROFIBUS can be used in measure mode as fully-fledged interfaces.
• If the sensor is in menu mode, the PROFIBUS is active. Queries from the control are
not processed and the process data are frozen (indicated by the constant scan num-
ber).
• If the sensor is in command mode, the PROFIBUS is active. Queries from the control
are not processed and the process data are frozen (indicated by the constant scan
number).
• If the sensor is simultaneously operated with LESsoft and PROFIBUS, the PROFIBUS
is active. Queries from the control are processed with a delay; the process data are
also updated with a delay (indicated by the slowly increasing scan numbers). The
update occurs every 200ms.
• The input signals via Ethernet, PROFIBUS and signal lines have equal priority. The first
incoming signal is executed.
• The sensor is configured via the LESsoft configuration software.
Compared to device model LES 36…/VC6 with analog output, the PROFIBUS model has
the following additional functions:
• Output of up to eight measurement values (two measurement values per EAW).
• Output of the state of the object detection in up to four EAWs and four AWs.
• Output of the state of the edge detection AND object detection (logical AND combi-
nation).
• Transmission of scan number, sensor state and of the current inspection task.
• Selection of up to 16 inspection tasks.
• Activation and trigger via PROFIBUS.
