4.3 PROFIBUS Address Set via Parameter or SSA Command
If all hardware switches are set to ON or OFF (factory switch setting), the PROFIBUS address can be set via
parameter 9-18 Node Address
or the PROFIBUS SSA command. The address becomes valid after the next power cycle.
4.4 Commissioning
Prerequisites:
The station address of the VLT® Decentral Drive FCD 302 must be the same as for VLT® Decentral Drive FCD 300.
Procedure
1. Cycle power to the FCD 302.
The master/PLC now recognizes FCD 302 as an FCD 300.
Example:
A solid green NS LED on the VLT® FCD 300 PROFIBUS Converter MCA 117 indicates that communication between master and slave is
established.
If the NS LED flashes, the master/PLC has not recognized the FCD 302.
