You can directly access the states/events in the XC100 with the
Browser commands. The Online description in the XSoft can be
found at: ‹Resources
l PLC-Browser›.
“canload” browser command
The “canload” function is contained in the “XC100_Util.lib”. They
can be called up as browser commands. With this command, the
current utilization of the CANopen bus is determined. The data
utilization of the bus is determined via and integration time and
determined in relation to the CAN baud rate.
You will receive the following information after the browser
command is called:
CAN Busload = 51 Percent
Baud rate: 125 Kbaud
Integration Time: 504 ms.
With a bus loading of 75 percent or higher, a warning appears -
ATTENTION: HIGH BUSLOAD.
In addition to the browser command, a function call for the
CAN_BUSLOAD function block to determine the CAN bus loading
from the user program is available.
