Circuit table

Circuit records are used to prevent Omnicomm from sending multiple messages over different connections where these messages would collide or interfere with each other. Circuit records are located in the Circuit table and are created and edited using the circuit Row Edit dialog box,

A connection is a path from Omnicomm to a single port on one remote. In the case of multi-dropped remotes, the same connection is used to communicate with any of the remotes.

A single circuit consists of one or more physical connections. Two physical connections are in the same circuit if they either directly or associatively conflict with each other. You can associate a connection with a circuit record to prevent Omnicomm from sending multiple messages over different connections where these messages would collide or interfere with each other. Omnicomm will never attempt to perform more than one operation at a time over a single circuit, regardless of the number of connections in that circuit.

An example of direct conflict is a leased line and a dial-up both going to the same single ported remote. Separate commands cannot be sent down the two lines without colliding when they reach the single remote port.

An example of associative conflict would be two single ported remotes, both sharing the same leased line but each with its own dial-up line as well. The two dial-up lines do not conflict with each other, but each line conflicts with the leased line. Hence, they must grouped in the same circuit.
