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