Performance Considerations
Actual performance of an MicroLogix 1400 controller varies according to:
• size of Ethernet messages.
• frequency of Ethernet messages.
• network loading.
• the implementation of and performance of your processor application
program.
MicroLogix 1400 and PC
Connections to the
Ethernet Network
The MicroLogix 1400 Ethernet connector conforms to ISO/IEC 8802-3 STD
802.3 and utilizes 10/100Base-T media. Connections are made directly from
the MicroLogix 1400 to an Ethernet hub or switch. The network setup is simple
and cost effective. Typical network topology is pictured in Figure 76 on
page 283.
