FaScan

Overview

FaScan capabilities

FaScan helps an engineer see the local network, find available devices, check Modbus TCP, work with CoDeSys V3 tags and analyze data in one workspace.

FaScan main workspace
A complete workflow: network, devices, live data and analysis tools in one interface.

At a glance

Overview sections

01

IP Scanner

Find IPv4 devices, check reachability and move from discovery to diagnostics.

 02

LIVE mode

Track local network state in real time during commissioning and troubleshooting.

 03

Modbus TCP Master

Read coils, discrete inputs, holding registers and input registers without a separate test tool.

 04

CoDeSys V3 tags

Use symbolic configuration and meaningful variable names instead of manual address lookup.

 05

Device grouping

Organize large signal sets into devices, folders and logical groups.

 06

Header controls

Keep lamps, buttons, progress bars, values and messages in the device header.

 07

Data logging

Record selected parameters for later analysis, comparison and fault hunting.

 08

Charts

Use time graphs, XY Plot and distribution charts for engineering analysis.

01 / Device discovery

IP Scanner

IP Scanner helps you quickly understand which devices are available on the local network. Select a network adapter, set an IPv4 range and start scanning. FaScan shows discovered hosts, reachability, MAC addresses, vendor information and TCP port checks.

  1. Open scan settings and select the required network interface.
  2. Set the address range or use the detected subnet range.
  3. Start scanning and select a discovered device for further checks.

02 / Real time

LIVE mode

LIVE mode shows the current network state, not just a single scan snapshot. During commissioning you can immediately see when a device appears, disappears, changes reachability or stops responding while a cabinet, switch, controller or gateway is being checked.

  1. Enable LIVE after an initial scan or before checking an unstable network segment.
  2. Watch status changes without restarting the scan manually.
  3. Use LIVE together with autoscan to catch intermittent communication issues faster.

LIVE mode helps track network composition during real-time troubleshooting.

03 / Modbus TCP

Modbus TCP Master

Modbus TCP Master checks device communication without another test application. Specify IP address, port, Unit ID, function, start address and quantity. FaScan adds the request to the workspace, polls it and displays values in a readable table.

  1. Create a Modbus TCP device or choose a discovered IP address from the scanner.
  2. Add a read request for coils, discrete inputs, holding registers or input registers.
  3. Open the traffic window when you need to inspect requests, responses, timing and protocol errors.

04 / Symbol configuration

CoDeSys V3 tags

CoDeSys V3 tag support lets you work with meaningful variable names, not only numeric register addresses. After loading a symbol configuration, select variables from the tree, add them to monitoring and use them in rules, device headers and analysis.

  1. Open the CoDeSys manager and load the project symbol XML.
  2. Find the required variable in the tree, including structure fields.
  3. Move the tag into the monitoring workspace and set the target connection.

The CoDeSys V3 tree lets you choose variables by project name and structure.

05 / Project structure

Device grouping

Grouping keeps large signal lists readable. Put data into devices, folders and logical groups such as line, cabinet, drive, temperatures, alarms or temporary checks. This makes the project easier to navigate and maintain.

  1. Create a device or folder for a logical group of signals.
  2. Drag rows into the required group and rename them clearly.
  3. Keep related parameters together to speed up diagnostics.

Devices and folders turn signal lists into a clear structure.

06 / Device panel

Header controls

A device header can work as a compact operator panel for debugging. Put the most important elements there: current values, state lamps, control buttons, progress bars or rule-based text messages.

  1. Select key parameters and show them in the device header.
  2. Add lamps, messages, progress bars or buttons for quick actions.
  3. Use the header as a mini panel instead of searching important rows in a large table.

Key indicators and controls stay attached to the device.

07 / Recording

Data logging

Logging is used when the history matters, not only the current value. Select the required rows, start recording and use the saved data later for charts and comparison. This helps find rare faults, value jumps and unstable operating modes.

  1. Mark the parameters that should be recorded.
  2. Run polling and data recording for the required test period.
  3. Open the saved log in charts for analysis.

08 / Analysis

Charts

Charts turn a value log into a readable picture. A time graph shows signal dynamics, XY Plot compares one value against another, and distribution shows the most frequent range and rare outliers.

  1. Open a log after data recording.
  2. Choose a time graph, XY Plot or distribution chart depending on the analysis task.
  3. Use cursors, ranges and multiple channels to find the cause of a problem faster.
