FOXBORO P0916AG 福克斯波罗I/A Series系统

系统特点：安全性高 安全度高、高精度，安全 耐用

系统环境：常温 、正常、耐高温

日常点检工作：定期进行CPU的电池的电压检测，定期对构成PLC系统的相关设备的点检和维护，如UPS定期维护，利用停机时机，对PLC各控制柜进行人工降尘降温PLC程序的定期人工备份和电池备份及各相关坏器件的更换等工作。

对控制系统来说，由于CPU是二进制的，数据的每位有“0”和“1”两种状态，因此，开关量只要用CPU内部的一位即可表示，比如，用“0”表示开，用“1”表示关。而模拟量则根据精度，通常需要8位到16为才能表示一个模拟量。最常见的模拟量是12位的，即精度为2-12，精度约为万分之二点五。当然，在实际的控制系统中，模拟量的精度还要受模拟/数字转换器和仪表的精度限制，通常不可能达到这么高。

System features: high safety High safety, high precision, safe and durable

System environment: normal temperature, normal, high temperature resistance

Daily spot check: periodically check the voltage of the CPU battery, periodically check and maintain the related equipment that constitute the PLC system, such as UPS regular maintenance, take advantage of downtime, and manually backup the PLC program for dust reduction and cooling, battery backup, and replace the related bad devices.

For the control system, because the CPU is binary, each of the data has two states of "0" and "1", so the switch quantity can be expressed as long as the CPU is a bit inside, for example, with "0" to indicate on, with "1" to indicate off. The analog quantity, depending on the accuracy, usually requires 8 to 16 bits to represent an analog quantity. The most common analog quantity is 12-bit, that is, an accuracy of 2-12, with an accuracy of about 2.5 millionths. Of course, in the actual control system, the accuracy of the analog quantity is also limited by the accuracy of the analog/digital converter and the instrument, and it is usually impossible to reach such a high level.
