mayank_254 RNF(Antares):lblSharedPostList_Posts 20 RNF(Antares):lblSharedPostList_Rating (0)	Hi everyone, I have a Sinamics G120 Cu240E-2 and BOP-2 mounted on it. Now when i power on the module, the BOP-2 shows the message "CU Busy" and the message does not goes away. i cannot access any parameters because of this. There is no electrical connection to PM240 as of now as i was trying just to access the parameters. Also, do we need to install any driver for USB Starter Kit for going online through Starter?

JensS RNF(Antares):lblSharedPostList_Posts 739 RNF(Antares):lblSharedPostList_Rating (53)	When parameter values are being changed, the BOP sometimes displays the message "bUSY". This means that the inverter is currently processing a higher-priority task. e.g.: When quick commissioning is being completed, the message "bUSY" is displayed on the BOP. This means that the system is in the process of calculating the control data and saving the parameter values in the EEPROM.

mayank_254 RNF(Antares):lblSharedPostList_Posts 20 RNF(Antares):lblSharedPostList_Rating (0)	Dear Jens S, No thats not the case in here, at the start up only when i give the CU 24V supply, the BOP-2 shows the message "CU Busy". this message display doesnot changes and because of this only i am not able to access any parameters also. i hope i have myself clear on my doubt here.
