11.5.2 Error counter reset from the application
The L_ECAT_ReadErrCnt (FB)
( 116)
function block enables the PLC application to access
the telegram failure error counter by reading.
The
L_ECAT_ResetErrCnt (FB)
( 117)
function block resets the error counters to the initial
value 0.
Example
Once per minute the PLC reads the error counters and evaluates the contents. If it
recognises a error counter value of 250, the application will reset the error counters.
Depending on the EMC load of the network environment, approx. 1 to 2 frame errors per
day in the bus are normal. The error counters should not reach the value of 255.
