Bus termination

Note
PROFIBUS PA cable shield MUST be terminated at both ends of the cable for it to work
properly. Please refer to the PROFIBUS PA User and Installation Guidelines (order number

E.6

Power demands

To determine how many devices can be connected to a bus line, calculate the combined
maximum consumption of all the connected devices: 10.5 mA for each SITRANS LR200. Allow
a current reserve for safety.
E.7

PROFIBUS address

A unique PROFIBUS address identifies each device on the network.
• To set PROFIBUS address, see Device address (5.1.) (Page 136).
• To reset the PROFIBUS address to 126, see Master reset (4.1.) (Page 122).
Notes:
• It is possible to change the device address via a Class 1 master (for example, a PLC) and
lock the device address to prevent further changes.
• If this Address Lock is on, the PA address cannot be changed. This lock can be disabled
only by performing an Address Reset.
