FOXBORO P0960JA-CP40日常点检：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。

FOXBORO P0960JA-CP40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。

这是PLC控制器最基本、最广泛的应用领域，它取代传统的继电器电路，实现逻辑控制、顺序控制，既可用于单台设备的控制，也可用于多机群控及自动化线。如注塑机、印刷机、订书机械、组合机床、磨床、包装生产线、电镀线等。

FOXBORO P0960JA-CP40 Routine inspection: Periodically check the voltage of the CPU battery, periodically check and maintain the related equipment that constitutes the PLC system, such as the regular maintenance of UPS, the use of downtime, the manual dust removal and cooling of the PLC control cabinet, the regular manual backup of the PLC program and battery backup, and the replacement of various related bad devices.

FOXBORO P0960JA-CP40 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 internal one, 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.

This is the most basic PLC controller, the most extensive application field, it replaces the traditional relay circuit, to achieve logic control, sequence control, can be used for single equipment control, can also be used for multi-machine group control and automation line. Such as injection molding machines, printing presses, stapler machines, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.
