Connect

Connect mode is used to enable a remote ethernet host to intrusively interrupt communication between two serial devices connected to the IP100.

Connect

Under normal circumstances, there is a bidirectional communications between devices on the two IP100 serial ports. If the IP100 detects a virtual serial TCP socket request, then it overrides the serial-to-serial communications. While the TCP socket is established, any data from the other serial device is discarded.

The configuration parameters are:

Src Port Source port serial port number in the range 0 to 4.
Dst Port Destination port serial port number in the range 0 to 4. This must also be used in a virtual serial server or a virtual serial client connection.

Example: Master RTU and SCADA Host with Flowmeter Slave

In the diagram, the Master RTU is the source serial port. The Flowmeter is the destination serial port. The SCADA Host is a virtual serial client. The IP100 is configured to use both connect mode and virtual serial server mode. When the SCADA Host and the Flowmeter exchange messages there is no exchange of messages between the Master RTU and the Flowmeter. When the SCADA Host connection to the IP100 is not active the Master RTU and Flowmeter resume the exchange of messages. In this example, the modbus protocol is used. However, both connect mode and the virtual serial modes do not require any specific protocol.
