DCS的SFC组态过程

本文介绍DCS(EMERSON DeltaV)的SFC(Sequential Funtion Charts) 具体组态过程。

DCS的SFC组态过程

SFCs(Sequential Function Charts):EMERSON DeltaV 的一种CONTROL MODULE(控制模块)。

Using SFC-T101

1.SFC-T101:Sequential Function Chart for automated STARTUP and SHUTDOWN

2.NS-T101：Named Set NS-101, 1=STARTUP 255=SELECT SEQUENCE

3.MTR-102：联锁马达控制模块（进料马达）

4.FIC-102：常规PID控制模块（进料流量）

5.XV-101： 电磁阀控制模块

组态步骤：

Step 1.Create Named Set NS-101 using DeltaV Explorer.

Step 2.Modify Properties and names and values as shown below.

Named Set NS-101(Name- Case sensitive) Visible User Selectable 1=STARTUP YES YES 255=SELECT SEQUENCE YES NO

Step 3.Use Control Studio to create Sequential Function Chart SFC-T101.Select New and change Algorithm Type to Sequential Function Chart.

Step 4.Create parameter MESSAGE(Named Set,NS-101).

Step 5.Create Sequential Function Chart using Steps,Transition and Terminations from the All SFC Items Palette.

‘MASSAGE’:= ‘NS-T101:SELECT SEQUENCE’

’= ‘NS-T101:STARTUP’

Open the block valve XV-101

Set the flow rate to 50GPM FIC-102

Start pump MTR-102
