The L_ECAT_ErrCnt structure
The L_ECAT_ErrCnt structure contains the error counters of the single ports of a connected
device.

Inputs (VAR_INPUT)
Outputs (VAR_OUTPUT)
TYPE L_ECAT_ErrCnt :
STRUCT
Port0 : BYTE;
Port1 : BYTE;
Port2 : BYTE;
Port3 : BYTE;
END_STRUCT
END_TYPE
Identifier/data type Description
Port[n]
BYTE
Error counter value of the errors recorded at the port[n]
n: 0 ... 3
Function: This function block resets the telegram error counters of all connected
slaves (see Error counters of the EtherCAT slaves
( 143)
). This block
should be executed before one of the telegram error counters of the
slaves has reached the maximum value of 255.
Library: SM_Ethercat.lib
Visualisation: VISU_L_ECAT_ResetErrCnt
Identifier/data type Meaning/possible settings
bExecute
BOOL
The function block is activated in an edge-controlled manner:
• Positive edge (TRUE) = function block is executed.
Identifier/data type Meaning/possible settings
bDone
BOOL
FALSE: Function block is active or has not been called
TRUE: Function block has been executed.
bError
