Method of changing IP and station name using BOP panel for Siemens VSD G120 series

The Siemens G120 series frequency converters basically support communication control, such as Profibus and profinet protocols. When it comes to modifying addresses and station names, they are usually rewritten using software such as TIA and STARTER, or modified through the super panel IOP-2. However, the manual does not mention how to modify these parameters through the BOP panel. After practical exploration, I found that the BOP panel can also modify these parameters, The method is as follows:

1、 The G120C PN type frequency converter uses profinet communication, but it can be started, stopped, and adjusted using the manual function (HAND/AUTO) of the panel, which can directly determine the quality of the frequency converter without passing through the network.

3、 P3 is set to 4 first, and the station name P8920 can also be configured using a simple panel like BOP-2, but the following cannot be configured:
P8921—— r8931 IP Address
P8922—— r8932 Default gateway
P8923- r8933 subnet mask
P8924—— r8934 DHPC mode

4、 In practical use, it was found that as long as the station name P8920 (with a total of 240 subscripts, corresponding to a maximum of 240 values) is set, such as IND [000], IND [001], IND [002]… IND [239] is actually an ASII value, it can be connected to the profinet. The P8921-P8924 on the top should not be ignored, and the upper level should have the opportunity to assign them additional values.

5、 Method for changing P8920 parameters in BOP-2
A. P8920=0, all its subscripts ind [000] [001] [002] until the corresponding value of [239] must be set to 0. Remember to press the OK key every time you modify one;
B. P8925=3, press the OK key to delete all IP configurations;
C. Power off the frequency converter for at least 20 seconds;
D. Power on again and re-enter the corresponding station name value (ASII) in P8920, [000] – [239], usually using 8.
E. P8925=2, power off for more than 20 seconds;

6、 BOP-2 can directly upload data other than the station name P8920-P892, such as motor current and power, and then download it to a new frequency converter. However, the parameters of P8920 can only be manually inputted according to the above process. Remember to set p971=1 after debugging and save the parameters (automatically changing to 0 after successful saving), otherwise the parameters will be lost after power outage.
