6.4.2.1 General
"DP1 (PROFIBUS)" Diagnostics LED
The PROFIBUS diagnostics LED is located on the front of the control unit (see
Section 6.4) Its statuses are described in the following table.

6.4.2.2 Setting the PROFIBUS Address
Two methods are available for setting the PROFIBUS address:
• The address switches (DIP switches) on the front of the control unit behind the
cover plate (see Section 6.4.1).
If you use the address switch, parameter p0918 is read only and displays the
address that is set.
If the switch is reset, the new setting does not become effective until the control
unit is reset.
• Entering parameter p0918 on the operator panel.
You can only do this if the address has been set to 0 or 127 using the address
switch, that is, all switches from S1 to S7 are set to ON or OFF.
In this case, changes become effective immediately.
