在工业应用中，最普遍的两个元素就是数字量和模拟量，今天我们聊一聊模拟量的编程， 模拟量作为工业控制中必不可少的一个元素，由模拟量传感器发出信号，最终由控制单元接收，可以表示温度，压力，流量，液位等等！在PLC控制系统中，最常见的模拟量信号为4-20ma，以前的文章我们也提到过，4-20ma作为行业标准有着得天独厚的优势。 那么除了4-20ma外，我们还可以用-10V~ +10V或者0-20ma等等，这些信号由传感器发送出来，最终进入到PLC模拟量输入通道，...
随着工业自动化的发展，工控机已经广泛应用于各工业现场中，其在工业领域的主要用途是是用于工业自动化系统中需要计算机的地方。和PC 机的主要区别是抗干扰能力强，可靠性高。 工控机已具备哪些功能？ 1、采用符合“EIA”标准的全钢化工业机箱，增强了抗电磁干扰能力； 2、采用总线结构和模块化设计技术。CPU及各功能模块皆使用插板式结构，并带有压杆软锁定，提高了抗冲击、抗振动能力； 3、机箱内装有双风扇，正压对流排风，并装有滤尘网用以防尘； 4、配有高度可靠的工业...
