51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器

51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器是采用"顺序扫描，不断循环”的方式进行工作的。即在51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器运行时，CPU根据用户按控制要求编制好并存于用户存储器中的程序，按指令步号(或地址号)作周期性循环扫描，如无跳转指令，则从条指令开始逐条顺序执行用户程序,直至程序结束。然后重新返回条指令,开始下一轮新的扫描。在每次扫描过程中，还要完成对输入信号的采样和对输出状态的刷新等工作。51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器的一个扫描周期必经输入采样、程序执行和输出刷新三个阶段。

51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器在输入采样阶段:首先以扫描方式按顺序将所有暂存在输入锁存器中的输入端子的通断状态或输入数据读入,并将写入各对应的输入状态寄存器中，即刷新输入。随即关闭输入端口，进入程序执行阶。51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器在程序执行阶段:按用户程序指令存放的先后顺序扫描执行每条指令,经相应的运算和处理后,其结果再写入输出状态寄存器中，输出状态寄存器中所有的内容随着程序的执行而改变。输出刷新阶段:当所有指令执行完毕,输出状态寄存器的通断状态在输出刷新阶段送至输出锁存器中，并通过一定的式(继电器、晶体管或晶闸管)输出，驱动相应输出设备工作。

51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器的工作过程，51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器的运行方式初研制生产的

51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器主要用于代替传统的由继电器接触器构成的控制装置，但这两者的运行方式是不相同的:

(1)继电器控制装置采用硬逻辑并行运行的方式，即如果这个继电器的线圈通电或断电,该继电器所有的触点(包括其常开或常闭触点)在继电器控制线路的哪个位置上都会立即同时动作。

(2)51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器的CPU则采用顺序逻辑扫描用户程序的运行方式，即如果一个输出线圈或逻辑线圈被接通或断开，该线圈的所有触点(包括其常开或常闭触点)不会立即动作，必须等扫描到该触点时才会动作。为了消除二者之间由于运行方式不同而造成的差异，考虑到继电器控制装置各类触点的动作时间一般在100ms以上,而51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器扫描用户程序的时间一般均小于100ms,因此，51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器采用了 -种不同于一般微型计 算机的运行方式扫描技术。这样在对于I/O响应要求不高的场合, 51401583-100 EPNI   HONEYWELL  霍尼韦尔控制器 与继电器控制装置的处理结果上就没有什么区别了。

51401583-100 EPNI HONEYWELL controller works in a way of "sequential scanning and continuous circulation". That is, when the 51401583-100 EPNI HONEYWELL controller is running, the CPU periodically scans according to the instruction step number (or address number) according to the program compiled by the user according to the control requirements and stored in the user's memory. If there is no jump instruction, the user program will be executed one by one from the instruction until the program ends. Then return to instructions and start the next round of new scanning. In each scanning process, it is necessary to sample the input signal and refresh the output state. A scanning cycle of 51401583-100 EPNI HONEYWELL controller must go through three stages: input sampling, program execution and output refresh.

51401583-100 EPNI HONEYWELL controller in the input sampling stage: firstly, the on-off state or input data of all the input terminals temporarily stored in the input latch are read in sequence in a scanning way, and will be written into each corresponding input state register, that is, the input is refreshed. Then close the input port and enter the program execution stage. 51401583-100 EPNI HONEYWELL controller in the program execution stage: scan and execute each instruction according to the order in which the user's program instructions are stored, and after corresponding operation and processing, the result is written into the output status register, and all the contents in the output status register change with the execution of the program. Output refresh stage: when all instructions are executed, the on-off state of the output status register is sent to the output latch in the output refresh stage, and it is output through a certain formula (relay, transistor or thyristor) to drive the corresponding output equipment to work.

The working process of 51401583-100 EPNI HONEYWELL controller and the operation mode of 51401583-100 EPNI HONEYWELL controller were initially developed and produced.

51401583-100 EPNI HONEYWELL controller is mainly used to replace the traditional control device composed of relay contactors, but their operation modes are different:

(1) The relay control device operates in parallel with hard logic, that is, if the coil of the relay is powered on or off, all contacts of the relay (including its normally open or normally closed contacts) will act at the same time at any position on the relay control line.

(2) The CPU of 2)51401583-100 EPNI HONEYWELL controller adopts the operation mode of sequential logic scanning user program, that is, if an output coil or logic coil is turned on or off, all contacts of the coil (including its normally open or normally closed contacts) will not act immediately, and they will only act when the contact is scanned. In order to eliminate the difference caused by different operation modes between them, considering that the action time of various contacts of relay control devices is generally more than 100ms, and the scanning time of user programs of 51401583-100 EPNI HONEYWELL controller is generally less than 100ms, therefore, 51401583-100 EPNI HONEYWELL controller adopts an operation mode scanning technology different from that of general microcomputer. In this way, there is no difference in the processing results between the 51401583-100 EPNI HONEYWELL controller and the relay control device when the requirements for I/O response are not high.
