I am working with the PCAN-MiniDisplay and would like to display several parameters on the screen, such as the average gradient, sector length, and next sector distance. Below is the script I am using
The Global Settings, Messages, Variables, and Labels sections of the script have been configured as follows:
Variables: Defined for Avg_Gradient, Sector_Length, and Next_Sector_Distance.
Messages: The message with CAN ID 0x600 is enabled, but I am transmitting the data with a different CAN ID (0x621).

----------------------------Issue:
The script specifies CAN ID 0x600, but I am able to receive and display data even when the CAN message is transmitted with CAN ID 0x621.
The data is displayed correctly even when using an arbitrary CAN ID, not matching 0x600.
Could you kindly help me understand why this is happening? Is there any configuration setting or other underlying reason that allows the script to process data from a different CAN ID?
