Allowable Combinations of Controllers per Server Up to 10 non-redundant only Up to 10 redundant or
non-redundant in any
combination
Maximum Number of Nodes allowed including Controllers, Servers
and FIM-only chassis. 12
• Only qualified for redundant
Servers +10 non-redundant
controllers
• FIMs are not supported on a
Supervisory Ethernet system
in any configuration
24
Data Transmission Rate 10 Mbits/sec 5 Mbit/sec
Media Redundancy Non-redundant only Single cable or redundant media
operation supported.
Controller Definitions including PLCs
Multiple 1757-PLX52s per chassis are NOT supported. However, a
non-redundant 1757-PLX52 can reside in the same chassis as a
Logix 5550.
PLCs only count as controllers when SCADA connections are
defined against the PLC. Non-Redundant:
• 1 1757-PLX52
• 1 Logix5550
• 1 PLC5/C or E
• 1 SLC (Ethernet only)
Redundant:
• 2 1757-PLX52s in a Chassis
Pair with 2 1757-SRMs
• 2 1756-5555s in a chassis pair
with 2 1757-SRMs
(1) The CPM and FIM use 1 PCIC connection from the Server regardless of whether they reside on a Supervisory or I/O ControlNet. PLCs should be limited to 2 connections if
configured as SCADA controllers via RSLinx.
