Data Throughput
In tests performed using the RSLinx OPC Test Client, the ENI/ENIW
(series D) was connected to a MicroLogix 1500 with channel 0 set to
38.4 kbaud. The Ethernet port was connected to the computer
through a 10/100 Mbps switch.
The maximum number of minimum-sized packets per second that can
be transmitted through the ENI/ENIW (series D) at 100 Mbps to a
MicroLogix 1500 at 38.4 kbaud is 94 (94 words/second).
The maximum number of 100-word packets per second that can be
transmitted through the ENI/ENIW (series D) at 100 Mbps to a
MicroLogix 1500 at 38.4 kbaud is 15 (1500 words/second).
