3 3
The LED marked NS (FCD 302: NS2) indicates the network
status, that is, the cyclic communication to the PROFIBUS
master. When this light is a constant green, data exchange
between the master and the frequency converter is active.
The LED marked MS (FCD 302: BUS MS) indicates the
module status, that is, acyclic DP-V1 communication from
either a PROFIBUS master class 1 (PLC) or a master class 2
(MCT 10 Set-up Software, FDT tool). When this light is a
constant green, DP-V1 communication from master classes
1 and 2 is active.
For details of the full range of communications status
indicated by the LEDs, refer to chapter 8 Troubleshooting.
