Notes on PLC Web Browser

1.

This object only runs on local screens of:

cMT3072X and cMT3072XH (OS version 20200723 or later).

cMT3092X, cMT3152X, and cMT3162X (OS version 20201230 or later).

2.

PLC Web Brower object is designed specifically for connection to PLC’s built-in web server, allowing users to access PLC web page to configure PLC and view PLC data. Using PLC Web Browser to connect to other types of websites may lead to unexpected results or errors.

3.

Displaying relatively complex web pages using PLC Web Browser will occupy more memory and consume a large amount of CPU, which can slow down HMI’s operating speed. Users are advised to use change page function or a Direct/Indirect window to display PLC Web Browser object only when it is needed, to prevent reduction of system performance.

4.

As HMI memory is limited, when the PLC Web Browser occupies too much memory, the system will automatically stop PLC Web Browser to ensure proper operation of HMI.

5.

Due to rapid change in web technologies, it is not guaranteed that all PLC web servers are supported by PLC Web Browser in EBPro, and certain PLC web pages may not be correctly displayed using PLC Web Browser.

6.

When multiple PLC Web Browser objects are placed in a single window, only one of them will run while the rest remain ineffective.

7.

PLC Web Browser object displays web page on top of everything else even if there are other objects placed above it.

8.

When the PLC Web Browser is clicked or tapped in cMT Viewer running on a PC, smart phone or tablet device, the default browser for the device will be used to open the web page. Note that, in this case, to access the PLC within the same network as HMI, the device running cMT Viewer should also be in the same network as the PLC.

9.

Browsing web pages using PLC Web Browser on cMT-iV6 is not possible.
