1、plc模擬量輸進模塊擴展
這里以一路12位模擬量輸進為例，模擬信號以0～5V標準電壓的形式送進信號輸進端，應用12位A/D轉(zhuǎn)換芯片MAX187實現(xiàn)模數(shù)轉(zhuǎn)換。MAX187是12位串行A/D，具有較高的轉(zhuǎn)換速度，采樣頻率是75kHz，適用于較高精度的過程控制。考慮到實際產(chǎn)業(yè)現(xiàn)場中的高頻干擾，在采樣信號送MAX187之前還使用了低通濾波器濾波，如圖1所示。
圖1 低通濾波、放大器及A/D轉(zhuǎn)換
MAX187具有內(nèi)部參考電壓，既4#管腳(REF)為 4.096V，因此，A/D轉(zhuǎn)換的全量程為4.096V。而輸進信號是0～5V，因此，要加一級運放把0～5V轉(zhuǎn)換成0～4.096V后送進MAX187。AT89C52的P1.3和MAX187的片選端(CS)相連、AT89C52的P1.4和MAX187的串行時鐘信號端(SCLK)相連、AT89C52的P1.5和MAX187的串行數(shù)據(jù)輸出端(DOUT)相連。模擬量采樣的值存進單片機的內(nèi)存中，再由單片機的串行口傳送給PLC。A/D轉(zhuǎn)換的C51程序如下:
#Include
#Include
sbit IC4_S = P1^4; /* AD輸進端口設置*/
sbit IC4_D = P1^5;
sbit IC4_C = P1^3;
void input(void )
{ unsigned char idata i;
unsigned int idata result=0x0000;
IC4_C = 0; /* CS端為低電平*/
for(i=0;i<12;i++)
{ result = result << 1;
IC4_S = 0; /*時鐘端產(chǎn)生時鐘脈沖*/
IC4_S = 1;
if( IC4_D ) result++; /*從串行數(shù)據(jù)輸出端讀進A/D轉(zhuǎn)換數(shù)據(jù)*/
}
IC4_C = 1; /* CS端為高電平*/
pdat[1] = result;
}
MAX187的工作時序圖見圖2。
