Visualization Documentation – MOV_INCH Block

Usage of MOV_INCH Block through SCADA Template

The MOV_INCH block represents a motor-operated valve with inching capability.
It allows precise step-wise operation using manual inch commands and supports automatic mode via logic.
This block provides:

  • Real-time block icon feedback
  • Multi-tabbed faceplate for different access levels
  • Full diagnostics and configuration access

Integrating the MOV_INCH Block into Visualization steps are given below:

This block is available in the TPW HMI template under the Visu_page section. It can be reused by dragging into user visualizations.

Step-by-Step: Using MOV_INCH Block in Visualization

1. Open Your Visualization Page

  • Launch your CODESYS project.
  • Navigate to the visualization screen where you want to use the MOV_INCH (e.g., MOV_INCH, Main_HMI, etc.).

2. Insert the MOV_INCH Block Icon from Scada_test Visu Page

  • Open the Visualization Toolbox Go to Current Project.
  • Drag or drop the MOV_INCH Block icon to your Visualization page.
  • Or Just Copy the MOV_INCH Block Icon from the Scada_test visu page and Paste into your Visualization page.
  • Select the inserted MOV_Inch block icon.
  • click on the block icon Properties tab open automatically → Properties.
  • Go to the References and Expand the references.
  • you will see bl_MOV_INCH Expand that also.
  • set the path in front of the tagMOV_fp by Double clicking on empty space and select the required tag.
  • Build and run the project.
  • During runtime, confirm the valve responds and displays correct feedback.

MOV Block Icon – Visualization Behavior

Block Icon

  • Clicking the icon opens the MOV_INCH faceplate.

MOV Faceplate Overview

Faceplate includes the following tabs:

  1. Operator
  2. Basic
  3. Advanced
  4. Diagnostic

Faceplate - Operator Tab

Block Icon

Operation Mode

  • AUTO: Logic-controlled mode.
  • MAN: Allows manual operation via INCH commands.

Commands

  • OPEN: Prepares for open.
  • CLOSE: Prepares for close.
  • INCH: Executes the open/close command if issued within 10s.

Feedback Indicators

Feedback Item Condition Status Indicator
PERM OPEN If open permission is OK 🟢 = Open Permission OK
🔴 = Open Permission Not OK
PERM CLOSE If close permission is OK 🟢 = Close Permission OK
🔴 = Close Permission Not OK
INTERLOCK If interlock condition is satisfied 🟢 = Interlock OK
🔴 = Interlock Active
MOV BLOCK ICON Static display showing MOV block icon with Tag Number Icon is always visible with corresponding Tag No.
Valve Status Based on combined status of permissions and interlock Shows Open/Close/Moving based on live MOV condition

  • Run Feedback Time (sec): Time taken to receive run feedback.
  • ZS Feedback Time (sec): Time taken to receive open/close feedback.

Operational Summary:

  • OPENED TIME (hr): Total opened time.
  • CLOSED TIME (hr): Total closed time.
  • OPEN COUNT: Total number of openings.
  • CLOSE COUNT: Total number of closings.

Faceplate - Diagnostic Tab

Block Icon

Diagnostic Indicators

Feedback Item Condition Status Indicator
CMD_Fault Any fault signal is available 🔴 = CMD_Fault (Fault Active)
🟢 = CMD_Fault (No Fault)
FB_Fault Any fault signal available 🔴 = FB_Fault (Fault Active)
🟢 = FB_Fault (No Fault)
Interlock Interlock status 🟢 = Interlock (No Interlock)
🔴 = Interlock (Active)
PERM OPEN Open permission status 🟢 = PERM OPEN (Satisfied)
🟡 = PERM OPEN (Not Satisfied)
PERM CLS Close permission status 🟢 = PERM CLOSE (Satisfied)
🟡 = PERM CLOSE (Not Satisfied)
Trip_FB Trip signal status = TRIP OK
TRIP
TSO (Torque Open) Torque open limit status 🟢 = TSO (Limit OK)
🔴 = TSO (Limit Not OK)
TSC (Torque Close) Torque close limit status 🟢 = TSC (Limit OK)
🔴 = TSC (Limit Not OK)
ZSC (Valve Closed) Closed feedback status =ZSC (Feedback Received)
= ZSC(Feedback NOT Received)
ZSO (Valve Opened) Open feedback status = ZSO (Feedback Received)
= ZSO(Feedback NOT Received)

Best Practices

  • Always verify PERM OPEN, PERM CLOSE, and INTERLOCK before issuing commands.
  • Use the INCH command promptly within 10 seconds after selecting OPEN/CLOSE.
  • Monitor Diagnostic Tab for fault resolution.
  • Configure Timeouts for feedbacks to prevent false alarms.

MOV_INCH provides advanced control for motor-operated valves with inching capability, ideal for precise movement and enhanced diagnostics in industrial HMI systems.
