18.8 _ECAT_Slave_DIO_Set_Output_Error_Value

Syntax
U16 PASCAL_ECAT_Slave_DIO_Set_Output_Error_Value (U16 CardNo, U16 NodeID,
U16SlotNo, U16 Value)

Purpose
This is for setting the retentive status of each channel on remote DO module when EtherCAT
communication is disconnected.
Note: Please use _ECAT_Slave_DIO_Set_Output_Error_Mode (see section 18.7) to enable the retentive
function when EtherCAT communication is disconnected.

Parameter
Name Data type Unit Description
CardNo U16 Number Card No.
NodeID U16 Number Node ID
SlotNo U16 Number Slot ID
Value U16 Value
Bit0 ~ 15 represent the output channels Y0~Y15
respectively.
0: Output channel is off
1: Output channel is on

Example
U16 Status;
U16 CardNo=16, NodeID=1, SlotNo=0;
// Change the function of the first 8 channels to retentive function when communication is
disconnected.
U16 Value=0x0F;
Status=_ECAT_Slave_DIO_Set_Output_Error_Value (CardNo, NodeID, SlotNo, Value);
