Inquiry: "Connection to server is lost!" When Selecting Matching in mapp Vision HMI

Ask Questions Controls & Vision

Hello,

I am experiencing an issue while accessing the mapp Vision HMI to configure the ROI for the Matching function and would like to ask for your assistance.

1. System Configuration

  • CPU: 5APC2200_AL18_000
  • Vision Camera: VSC523R25.051P-000
  • Power Panel: 6PPT50.0702-16B
  • Function Used: mapp Vision Matching Function Block
  • Vision Component: gCamera_0

2. Purpose

Currently, I am unable to configure the ROI for the Matching function directly on the T50 touch panel, so I am trying to configure the Matching ROI using the mapp Vision HMI.

After changing the IP address of the T50, I accessed the mapp Vision HMI using the following address:

http://192.168.10.161:81/index.html?visuid=mappVision

I then proceeded as follows:

  1. Select Vision Component: gCamera_0
  2. Select Function: Matching
  3. Configure the ROI on the Matching screen

3. Issue

The connection works normally up to the point where I select gCamera_0 as the Vision Component.

However, as soon as I select Matching under Function, the following error message appears on the T50:

Connection to server is lost!

After this message appears, the Power Panel T50 screen restarts.

This issue occurs repeatedly, so I am currently unable to access the Matching screen or configure the ROI.

4. Questions

Since I cannot configure the Matching ROI directly on the T50, I am trying to configure it through the mapp Vision HMI.

The mapp Vision HMI itself can be accessed normally. However, as soon as I select gCamera_0 → Matching, the message Connection to server is lost! appears and the T50 screen restarts.

Could you please advise on the following?

  • What could cause the Connection to server is lost! error when selecting the Matching function?
  • What could cause the Power Panel T50 screen to restart?
  • What is the correct procedure for accessing the Matching function and configuring the ROI using the mapp Vision HMI?

Please let me know how this issue can be resolved and if there are any additional settings or configurations that I should check.

Thank you.

Hello,

Have you tried accessing the mapp Vision visualization from a PC’s web browser? Is it the same?

Hello,

Mapp Vision works fine when I access it through a web browser on my PC.

However, I’m experiencing connection drops when accessing it from the T50, so I wanted to ask about this issue and see if there’s anything I should check.

I believe the T50 is too weak for displaying the mapp Vision visualization. You can increase the watchdog or disable it completely.

Hi,

I tested the watchdog by changing the value from 0 to 90,000, but it still doesn’t work properly. I’ve attached a video showing the configuration and test results.

Please let me know if there is another solution.
