Issues regarding remote transmission of the configuration screen
Thread Content
The facility where I work has two control rooms, both of which use Siemens PLC300 systems. The two PLC units and their configuration interfaces are located in separate control rooms. I want to be able to transmit the control data from the lower-level rooms to the upper control room; by installing a computer there and loading the configuration software, could information be transmitted via a switch? Is there anything else that needs to be added to the hardware part? Will everyone be able to understand it if I write it this way?

It depends on what you use for your HMI screen; if it’s WINCC, you need to purchase a license, and you also have to consider the number of points (the total for both PLCs)； If domestic products like KingView are used as well, they’re cheaper ； Of course, there are cracked versions as well, but they are not recommended. (Supports legitimate software)! The data can be directly obtained from the underlying PLC. The hardware is simple; it all uses the DP protocol, and there are also models with DP to Ethernet converters.
Since switches are supposed to use Ethernet for communication, the original poster can buy an upper-level computer, configure and clone the screen display from the computers below, and then change the IP addresses of those computers. If the Ethernet distance exceeds 100 meters, use a fiber optic converter.

The standard approach is to use an additional computer for communication between the two PLCs; this computer serves as an engineer station where the two original screens are combined. Then, two separate accounts are created on the other two computers, allowing users to log in with those accounts to view different screens. Done
