SST-PB3-REM SST 控制系统

（1）PLC程序的正确性。

正确的程序必xu能经得起系统运行实践的考验。

（2）PLC程序的可靠性。

●能保证系统在正常和非正常（短时掉电、某些被控量超标、某个环节有故障等）情况下都能anquan可靠地运行。

●能保证在出现非法操作（如按动或误触动了不该动作的按钮等）情况下不至于出现系统失控。

（3）PLC参数的易调整性好。

经常修改的参数，在程序设计时必xu考虑怎样编写才能易于修改。

（4）PLC程序结构简练。

简练的程序，可以减少程序扫描时间、提gaoPLC对输入信号的响应速度。

（5）PLC程序的可读性好。

(1) The correctness of PLC program.

The correct program must be able to stand the test of system operation practice.

(2) Reliability of PLC program.

● Can ensure that the system can operate anquan reliably under normal and abnormal conditions (short-term power failure, some controlled quantities exceed the standard, a fault in a certain link, etc.).

● It can ensure that the system will not be out of control in the case of illegal operations (such as pressing or accidentally touching the button that should not be moved, etc.).

(3) PLC parameters are easy to adjust.

Frequently modified parameters, in the program design must consider how to write in order to be easy to modify.

(4) The PLC program structure is concise.

The simple program can reduce the program scanning time and improve the PLC's response speed to the input signal.

(5) PLC program readability is good.
