How to set up remote monitoring?

On-site, a Siemens PLC is used to control a large motor, and in the control room (Location A), WINCC installed on a computer is used to monitor parameters such as the motor’s temperature and oil pressure. Now, it is desired to create a remote display in the office that provides similar monitoring capabilities for the motor’s temperature, oil pressure, etc., as those available in the on-site control room. Condition: The office (Location C) is more than 300 meters away from the control room (Location A) ； Another control room on site (Location B) has a switch connected to the office LAN, and the distance between control room (Location B) and the control room (Location A) is approximately 100 meters. Dear sea friends: What are the methods available to monitor the site from the office as well? Method 1: WebNavigator. I don’t know how to use it (the process of setting it up, the steps involved), nor do I know what items need to be purchased or what the price is (is it suitable or not?) ) Method 2: VNC or Windows Remote Desktop connection (but the computer in the control room also needs to be locked). Method 2 isn’t very good either, as the office managers might see us playing games; therefore, Method 1 is the best option. As a last resort, we can only use Method 2. I hope everyone can offer some helpful suggestions – thank you!
