Allen-Bradley SLC 500 Quick Start

1–2 SLC 5/05 Ethernet Processor Features
Publication 1747-10.4
SLC 5/05 (1747-OS501, FRN 3) processors support
RS232-to-Ethernet channel-to-channel passthru. See Chapter 5 for
more information on using the new passthru feature.
Actual performance of an SLC 5/05 processor varies according to:
• size of Ethernet messages
• frequency of Ethernet messages
• network loading
• the implementation of and performance of your processor
application program
