(2) When I-8K AIO modules are in the I-8000 controller, then please refer to thedemo in section 7.6.2.7.6.1 I-8k Modules in slots of LinPAC-8000In this section, this demo program – i8kaio.c will illustrate how to control the AI/AOwith the I-8024W ( 4 AO channels ) and I-8017HW ( 8 AI channels ) module and they are inslot 1 and slot 2 of the LinPAC-8000 separately.The address and baudrate in the LinPAC-8000 are constant and they are 00 and115200 separately. The result of this demo lets AO voltage channel 0 of I-8024W output5.5V and AI channel 2 of I-8017HW input. The source code of this demo program is asfollows:#include#include#include "msw.h"char szSend[80], szReceive[80];DWORD dwBuf[12];float fBuf[12];/* ------------------------------------------------------------------- */int main(){int i, wRetVal,j;float fAi;int hAi, chAi, Succ;int Arr_hAi[5];float Arr_fAi[5];//I-8024wRetVal = Open_Slot(1);if (wRetVal > 0) {printf("open Slot failed!\n");return (-1);}//I8024 InitialI8024_Initial(1);//I8024_AO OutputI8024_VoltageOut(1,0,5.5);Close_Slot(1);//I-8017HwRetVal = Open_Slot(2);if (wRetVal > 0) {printf("open Slot failed!\n");LinPAC-8x4x SDK:263
