7. Demo of LinPAC-8000 Modules With C LanguageIn this section, we will focus on examples for the description and application of thecontrol functions on the I-7000/I-8000/I-87k series modules for use in the LinPAC-8000.After you install the LinPAC-8000 SDK, all these demo programs as below are in the pathof “c:/cygwin/LinCon8k/examples”.7.1 I-7k Modules DIO Control DemoThis demo – i7kdio.c will illustrate how to control DI/DO with the I-7050 module (8 DOchannels and 7 DI channels). The address and baudrate of the I-7050 module in theRS-485 network are 02 and 9600 separately.The result of this demo allows the DO channels 0 ~ 7 output and DI channel 2 input.The source code of this demo program is as follows:#include#include#include "msw.h"char szSend[80], szReceive[80], ans;WORD wBuf[12];float fBuf[12];/* ------------------------------------------------------------------- */int main(){int wRetVal;// Check Open_Com3wRetVal = Open_Com(COM3, 9600, Data8Bit, NonParity, OneStopBit);if (wRetVal > 0) {printf("open port failed!\n");return (-1);}// ***** 7050 DO && DI Parameter *******wBuf[0] = 3;// COM PortwBuf[1] = 0x02;// AddresswBuf[2] = 0x7050;// IDwBuf[3] = 0;// CheckSum disablewBuf[4] = 100;// TimeOut , 100 msecondwBuf[5] = 0x0f;// 8 DO Channels OnwBuf[6] = 0;// string debugLinPAC-8x4x SDK:243
