Questions :   What is difference between 727CM Server mode and Client mode?

Problem Solving :

When using 727CM for remote installations, you must first decide whether to use Server mode or Client mode. The Server mode of 727CM is used for data transfer, where it can convert the RS-485 or RS-232 interface to a networking interface. The Client mode of 727CM is used to connect to another 727CM in Server mode and transfer data between them.

There are two situations that require a Server and Client structure:

1. When you need to transfer data over a longer distance, you can use remote installation mode and convert the transfer interface to Ethernet.
2. When you want to set up communication where one site (Server) receives data from multiple sites (Clients).

Furthermore, when establishing a connection between the Server and Client sites, messages or data are transferred from the Client site to the Server site. The Server site receives the message from the Client site and responds accordingly.

Therefore, before establishing a connection, you must ensure the transmitting and receiving sites are correctly identified. Set the transmitting site as Client mode and the receiving site as Server mode.
