OMRON NS Series PT Remote Access

Click the 'Write' button to save the settings. PT will prompt that a restart is required to take effect, confirm the restart.

After the restart is completed, PT's web server starts listening on TCP port 80 (default).

Web browser connection method

4.1 Basic Access

Start the browser on the computer and enter the following address in the address bar:

Http://(IP address of PT)/

For example, if the IP of PT is 192.168.0.1, input http://192.168.0.1/ The browser will first display the login authentication dialog box.

4.2 User authentication

The NS web interface uses HTTP Basic Authentication. The default factory credentials are:

Username: default

Password: default

After entering, click "OK". If the authentication is successful, you will enter the Menu Screen. If you need to change your username/password, you need to use the method described in "FTPFunction. pdf" in the accompanying tool of CX One or CX Designer to upload a new authentication file via FTP.

4.3 Direct Access to Specific Function Pages

The URLs for opening each functional module directly by bypassing the menu are as follows (replacing the IP address with the actual value):

Function page URL

Monitoring screen (default color) http://192.168.0.1/monitor.html

Monitoring screen (32768 colors) http://192.168.0.1/monitor32k.html

Monitoring screen (256 colors) http://192.168.0.1/monitor256.html

Monitoring screen (16 level grayscale) http://192.168.0.1/monitor16.html

operation screen http://192.168.0.1/operation.html

Browse storage card files http://192.168.0.1/memcard.html

configuration interface http://192.168.0.1/config.html

Menu Interface http://192.168.0.1/menu.html

Among them, monitor. html will follow the color settings in the configuration screen; Directly using monitors such as 32k. html will force the use of a specified color depth, which is not affected by configuration.

Detailed explanation of each functional interface

5.1 Menu Screen

The menu interface is a navigation page that contains four buttons:

Monitor: Enter the monitoring screen.

Operation: Enter the operation screen.

Files in Memory Card: Browse storage card files.

Configuration: Enter the web interface settings page.

Engineers can select the corresponding entry based on whether the current task is only for viewing or requires interaction.

5.2 Monitor Screen

The monitoring screen displays the current PT screen in read-only mode and automatically refreshes at fixed intervals. Main elements of the interface:

PT screen image area (BMP or PNG format).

The bottom displays' Latest Captured: YYYY-MM-DD HH: MM: SS', which is the timestamp of the last time the screen was captured.

Refresh mechanism: By default, the screen image is read from PT every 15 seconds. This interval can be adjusted to 0~65535 seconds in the configuration screen (if it is set to 0, it means that the browser will not be refreshed automatically and needs to be refreshed manually). The monitoring screen does not support touch operation and is only used for observation.

5.3 Operation Screen

The operation screen is the most powerful feature of NS Web interface - it simultaneously displays the PT screen and allows users to simulate touch operations through mouse clicks. The interface includes:

Central display of PT screen image (clickable area responds to left mouse button).

There is a "System Menu" button on the right or bottom (used to access the PT's system menu).

Operation logic:

When the user clicks any button or numerical input box on the webpage with the mouse, PT will receive the corresponding touch coordinates and perform the corresponding action.

The default screen refresh interval is 3 seconds (shorter than the monitoring screen to meet interactive response), and there is also a "delay after clicking" parameter (default 1 second), which means waiting for this time after clicking the mouse to read the PT screen again in order to see the operation result.

Touch screen lock: The configuration screen can be set to prohibit on-site personnel from touching the PT physical touch screen when the operation screen is turned on, to prevent conflicts caused by simultaneous operations by both parties.

System menu call: PT originally needed to press two diagonals simultaneously to bring up the system menu. However, on the operation screen, after clicking the "System Menu" button, users can pre-set the two corner positions to simulate pressing (top left+top right, bottom left+bottom right, top left+bottom left, top right+bottom right). Clicking on them will send the corresponding coordinates, and PT will display the system menu. Note: Even if there are functional objects in these positions, they will still be pressed together and should be carefully selected.

5.4 Files in Memory Card Interface

This interface allows remote browsing of files and directory structures in PT storage cards:

The root directory is displayed as'/at0 '.

The file list includes the file name, size (displayed as<dir>if it is a directory), and modification date.

Click on the file: The browser will attempt to open or pop up a download dialog box based on the file type. For text files such as CSV and TXT, they can be previewed directly in the browser.
