Ecat_Slave_Aio_Get_Input_Value - Delta EtherCAT Programming Manual

EtherCAT Programming Guide

19.1 _ECAT_Slave_AIO_Get_Input_Value


Syntax
U16 PASCAL_ECAT_Slave_AIO_Get_Input_Value (U16 CardNo, U16 NodeID, U16 SlotNo,
U16 *Value)

Purpose
This is for acquiring analog input value.
Note: Delta analog input module only allows users to measure voltage signal.
To measure the input current, you need to modify the wriing of the analog input module first. (Please refer to
the user manual of Delta analog input model regarding the wiring for current measurement.) After finishing
the wiring, users can convert the measurement into current by using the circuit with 250Ω- resistor.
