6.8.2 Control via PROFIBUS
Diagnostics LED "COM (PROFIdrive)"
The PROFIBUS diagnostics LED is located on the front of the Control Unit. Its states are
described in the following table.
Table 6- 28 Description of the "COM" LED
Color State Description
----- OFF Cyclic communication is not (yet) running.
Note:
The PROFIdrive is ready for communication when the Control Unit is ready for opera-
tion (see LED RDY).
Green Continuous light Cyclic communication is taking place.
Green 0.5 Hz flashing
light
Cyclic communication has still not been fully established.
Possible causes:
- The controller is not transmitting any setpoints.
- In isochronous mode, the controller did not send a Global Control or it sent a defec-
tive Global Control (GC).
Red 0.5 Hz flashing
light
PROFIBUS master is sending incorrect parameter assignment/configuration
Red 2 Hz flashing light Cyclic bus communication has been interrupted or could not be established.
Setting the PROFIBUS address
There are two ways to set the PROFIBUS address:
1.
Via p0918
–
To set the bus address for a PROFIBUS node using STARTER, first set the rotary
code switches to 0
dec
(00
hex
) and 127
dec
(7F
hex
).
– Then use parameter p0918 to set the address to a value between 1 and 126.
2. Via the PROFIBUS address switches on the Control Unit
–
The address is set manually to values between 1 and 126 using the rotary coding
switches. In this case, p0918 is only used to read the address.
Note
The rotary coding switches used to set the PROFIBUS address are located beneath the
cover.
