A connection is an open communication path between the data producer and the data consumer on the network. The connection includes information about the location of the consumer that significantly decreases the data overhead. By contrast, an unconnected message is a traditional message that uses the network address of the target device and the data address within the target. The 1756-CNB module supports a maximum of 64 bidirectional connections. These connections can be any mix of unscheduled and scheduled connections. If your application requires more connections, you can place additional 1756-CNB modules in the same chassis and on the same network as the first module to provide additional connections. Important:The number of connections that can actually be supported on a network is dependent upon the network configuration. For example, only 10 to 12 connections can be supported at an RPI (requested packet interval) of 5ms, and only 4 at an RPI of 2ms. Important:If you choose to use additional modules to provide additional connections, be sure to partition your application so that it best uses the additional modules.
