I am new to CAN communications and I would like to ask the following questions
1. The maximum transmission rate of the sent message in C125 is only 100Hz, how to communicate with the device with a baud rate of 500kbps, is it not normal communication
2.100Hz is equal to the baud rate

The Baud Rate of the bus is the bits per second that are transmitted / received. On the C125 this is set in the CAN tab of the selected bus when you open the Connections->Communications window. if you close the window you have show, you will see it the options box - you select the rate of 500k.

Now your message (of up to 8 bytes) is sent at 100 hz (100 times per second). Since this bus is shared, this would consume a very small fraction of the available bandwidth on the CAN bus.

These are not in conflict. Why don't you tell use what you are trying to do, and we can advise what an acceptable transmit rate you might want to use.
