12.4.2 Error counter reset from the application

The L_ETC_ReadErrCnt (FB) ( 145) function block enables the PLC application to access the error

counters by reading.

The

L_ETC_ResetErrCnt (FB) ( 146) function block resets the error counters to the value 0.

Example

Once per minute the PLC reads the error counters and evaluates the contents. If it recognises an

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 fieldbus are normal. The error

counters should not reach the value of 255.
