请问G120里P0922参数是什么意思？偶看了能找到的各种手册，没找到。问这个问题是在例程里看到的提示：ttention! Set the parameter for the selection of PROFIdrive Standard Telegram
P0922 = 354 (Siemens Telegram 354) before using the example program.
The settings cannot be changed, when Standard Telegram selected (P0700 = 6, P0922 = Standard Telegram).
