TCP Client Modbus RTU

[victorlam]

Under Administrator, there is settings on Main Parameter for Communication channel. There are many combination behind. I can see TCP client, TCP server, .. etc. For example, after TCP client, there is Master behaviour and Individual Comm mode.

May I know how the different combination works here? Or I need to remember that TCP client, must be Master and Individual.
Combination is as follows:-
TCP Client – Master – Individual
TCP Client – Slave – Shared
TCP Client – Slave – Individual
TCP Client – Master – Shared
TCP Server – Master- Individual
TCP Server – Slave – Shared
TCP Server – Slave – Individual
TCP Server – Master – Shared

Or only one combination works only under Administrator mode.

TCP Server or Client depends on who initiates the connection. For example, a Moxa server, and a Scada Client is a Scada initiator of connecting to Moxa with a real IP address in an open network or in a VPN network. If the Scada Server is a Moxa Client, then the initiator of the connection is Moxa and it accesses the Scada server at the real IP address.
Master/Slave everything is as usual in the Modbus protocol, for example. Scada can be in slave mode if you use the ModbusSlave driver.
Individually or in Shared, this is a way to specify an IP address, it is either taken from the specified settings or from the base of the device – the Call Sign

To reduce the list of combinations, describe what result do you need.
