TRICONEX 3704E工控接口模块
10.1.4自动/手动
在FCO101中，A/M模块配置为将阀门控制从自动PID控制器切换到脉冲发生器手动旋钮。按下A/M按钮，在（Loop01.S）设定点参数和（Loop01.V）阀门参数。在手动显示阀门参数的同时转动脉冲发生器旋钮，以改变数值显示器和水平条形图上的值；旋转脉冲发生器旋钮，同时显示设定点参数以更改数值和垂直S条形图。10.1.5修改FCO除了FCO101单回路控制外，还有几个其他出厂配置选项可用，例如比率设定控制（FCO105）和级联控制（FCO 121）。要下载另一个FCO，请执行中的步骤第2.7节。可以通过添加和删除功能块或更改默认值来更改FCO参数值。配置路线图如第2节所示。请注意，X表示按下步骤向下或向上按钮，a<>表示转动脉冲发生器旋钮。例如，要添加功能块，您可以
将执行以下步骤：
1.按ENTER/EXIT CONF。
2.按下“向下”键，直到显示视图。
3.转动脉冲发生器旋钮，直到显示ADD FB。
4.按下“功能块”菜单的“下一步”。
5.转动脉冲发生器旋钮，滚动浏览可用功能块，然后按存储添加功能块配置。6.要更改功能块参数，请将脉冲发生器旋钮转到编辑FB。7.按下“功能块”菜单的“下一步”。
8.将脉冲发生器旋钮转到所需功能块，然后按下“步进”。
9.将显示第一个功能块参数。例如，A/M传输块的RG PTR或模拟输入块的最小刻度。按“向下”键显示当前参数值，或使用脉冲发生器旋钮，用于选择不同的参数。按存储保存所有更改。
10.按退出按钮返回正常操作模式。
请注意，FCO101中的SETPT、报警、PID和ODC功能块都将AIN1称为RG PTR（范围指针）以确定功能块的操作范围。请注意，对配置可能需要更改引用的RG PTR。例如，在FCO105（比率设定控制）中控制器输出范围由AIN2的范围确定。尝试使用配置路径将模拟输入#1（AIN1）的默认0-100%范围更改为100.0-500.0°F
第2节中的映射或以下步骤：
1.按ENTER/EXIT CONF以显示循环。
2.按两次“向下”以显示视图。
3.转动脉冲发生器旋钮或使用箭头按钮显示编辑FB。
4.按下“下一步”以显示功能块菜单。
5.转动脉冲发生器旋钮或使用右箭头按钮显示AIN1。
6.按“向下”键显示最小刻度。
7.按下“逐步下降”以显示当前0%的范围。
8.转动脉冲发生器旋钮，在最后一位显示1。显示应为“0.00001”。
9.现在按下左箭头（标记）按钮。请注意，每次
按钮被按下。按下箭头按钮，直到显示屏显示“100.000”，然后按下存储按钮。
10.1.4 Auto/Manual
In FCO101, the A/M block is configured to switch Valve control from the PID controller in AUTO, to the Pulser
Knob in Manual. Press the A/M button to toggle the display between the (Loop01.S) setpoint parameter and the
(Loop01.V) valve parameter. Turn the pulser knob while displaying the valve parameter in manual to change the
value on the numeric display as well as the horizontal bargraph; turn the pulser knob while displaying the setpoint
parameter in Auto to change the numeric value and the vertical S bargraph.
10.1.5 Modifying an FCO
In addition to FCO101, Single Loop Control, there are several other factory configured options available, such as
Ratio Set Control (FCO105) and Cascade Control (FCO121). To download another FCO follow the steps in
Section 2.7.
Changes to an FCO may be made either by adding and deleting function blocks or by changing the default
parameter values. A Configuration Road Map is shown in Section 2. Note that an X represents pressing the STEP
DOWN or STEP UP button and a <> represents turning the pulser knob. For example, to add a function block you
would do the following steps:
1. Press ENTER/EXIT CONF.
2. Press STEP DOWN until VIEW is displayed.
3. Turn the pulser knob until ADD FB is displayed.
4. Press STEP DOWN for the function block menu.
5. Turn the pulser knob to scroll through the available function blocks and press STORE to add the function block
to the configuration. 6. To make changes to a function block parameter turn the Pulser Knob to EDIT FB.
7. Press STEP DOWN for the function Block menu.
8. Turn the pulser knob to the desired Function Block and Press STEP DOWN.
9. The first function block parameter will be displayed. For example, RG PTR for the A/M Transfer Block or
MINSCALE for the Analog Input Block. Press STEP DOWN to display current parameter value or use the
pulser knob to select a different parameter. Press STORE to save any changes.
10. Press EXIT to return to normal operation mode.
Notice that the SETPT, ALARM, PID, and ODC function blocks in FCO101 all refer to AIN1 as the RG PTR
(range pointer) to determine the operating range of the function block. Be aware that making changes to a
configuration may require changing referenced RG PTRs. For example, in FCO105 (Ratio Set Control), the PID
controller output range is determined by the range of AIN2.
Try changing the default 0-100% range of analog input #1 (AIN1) to 100.0-500.0°F using the Configuration Road
Map in Section 2 or the following steps:
1. Press ENTER/EXIT CONF to display LOOP.
2. Press STEP DOWN twice to display VIEW.
3. Turn pulser knob or use arrow button to display EDIT FB.
4. Press STEP DOWN to display Function Block menu.
5. Turn the pulser knob or use right arrow button to display AIN1.
6. Press STEP DOWN to display MINSCALE.
7. Press STEP DOWN to display current 0% of range.
8. Turn the pulser knob to display 1 in the last digit. Display should read “0.00001”.
9. Now press the left arrow (TAG) button. Notice that the decimal place will move one place every time the
button is pressed. Press the arrow button until the display reads “100.000” and press the STORE button.
