CIMPLICITYAbout Modbus TCP Server Communications
The Modbus TCP Server Communications option supports a multi-drop configuration with the Modbus TCP Server Communications enabler functioning as a server. In effect, the Modbus TCP Server Communications enabler presents the CIMPLICITY Points as if they were data values from one or more Modbus TCP Server devices.
The CIMPLICITY Points are mapped to Modbus Addresses, allowing a Modbus Client to obtain point values as if they were coils or registers on a server device.
SystemLink uses the Modbus TCP Server feature to enable CIMPLICITY to collect point values over the Internet using the Modbus protocol. The node that is set up as the client can collect data from the server nodes via the Internet.
Important: The Modbus TCP Server is not supported in a host redundant environment.
