Screen display
The display of the external BOP is identical to the built-in BOP, except that the external BOP
has a commissioning icon
mode.
On converter power-up, the converter-connected external BOP first displays "BOP.20" (BOP
for the SINAMICS V20) and then the firmware version of the BOP. After that it detects and
displays the baudrate and the USS communication address of the converter automatically.
See the following table for settable baudrate and address values. To change the baudrate,
set P2010[0]. To change the USS communication address, set P2011[0].
Baudrate
(bps)
9600
19200
38400
57600
76800
93750
115200
In case of any communication errors, the screen displays "noCon" which means that no
communication connection has been detected. The converter then automatically restarts
baudrate and address detection. In this case, check that the cable is correctly connected.
