Ethernet PLC-5

Performance

Considerations

Actual performance of an Ethernet PLC-5 controller varies according to:

•size of Ethernet messages

•frequency of Ethernet messages

•network loading

•the implementation of and performance of your controller application program

The following charts show performance of the Ethernet PLC-5 controller, depending on packet size.
