霍尼韦尔honeywell简易的数字控制器[0]

Posted on 2023年11月14日 by

DC1700系列过程控制器,产品规格书,选型参数

测试过的型号:DC1703-7-0-0-0-2-0-0-0关键特性:

  1. 最多可以有3个输出,输出支持电压和电流两种型式
  2. 10位精度
  3. 最多支持1个采样通道,支持电压和电流以及热电偶的输入,1s 4次的采样速度
  4. 支持RS485通讯
  5. 最多支持两个通道的数字输入
  6. 支持外部设定的输入
  7. 支持24VDC供电

以下是使用注意事项:(具体内容来自于产品说明书,另外有简易说明书)

硬件接线:

简易的使用说明:

在前面板按住setup键,再按上升键即可进行模式选择,常用模式如下:

1)配置模式conf

通过上下键输入密码20(默认),按setup键确认进入配置模式,根据具体应用设置相应的参数,对于用到的术语可见手册的附录

2)设置模式setp

通过上下键输入密码10(默认),按setup键确认进入配置模式,根据具体应用设置相应的参数,对于用到的术语可见手册的附录

3)设置操作模式Optr

操作模式可以设置设定目标值SP和显示过程指PV

其他注意事项:

再测试过程中对于配置模式和设置模型的参数修改都将使得控制器进入手动模式,只有操作模式下的SP值的设定不受此影响。

控制器有自动参数整定功能,在操作模式中输入密码0进入相应的参数设定可以开启和关闭此功能。

实际应用的调试过程:

1)连接控制器的相应的接线

2)配置控制器的相应配置参数

3)设置控制器的设定参数

4)手动控制,即开环模式,设定SP/P值检测输出的实际大小和物理含义

5)闭环手动调试模式,设定SP值,检测系统的稳定性,详细步骤可参照《液压伺服系统的调试》

应用过程的注意事项:

对于各式应用吗,需要给调试和检测时配置不同类型的物理传感器,便于确定主控传感器的状态。
