Other Communication Modules
Introduction
This section contains an overview of the available modules that provide
communication to S5 I/O and peer-to-peer communication.
If you are using a protocol to which you want to connect but is not described
in this manual, please check the websites of our encompass partners (such as
Woodhead/Molex, ProSoft, or HMS).
In-rack Modules
This section contains an overview of the available ControlLogix in-rack
modules that provide communication to S5 networks.
Profibus Network
This section describes modules that connects to a Profibus network.
Woodhead/Molex SST-PFB-CLX-RLL DP
One way of connecting to S5 I/O on Profibus is using a PROFIBUS DP
Scanner for the Logix Controller in the main rack. This is a third-party module
produced by Brad Communications (Molex/ Woodhead, Part Number SST-
PFB-CLX-RLL), which works with RSLinx software 2.2 OEM/Professional
or later.
This module slots directly into a local or remote ControlLogix chassis. It
enables communication between a CLX processor and DP remote I/O
devices on a PROFIBUS network, acting as a PROFIBUS DP remote I/O
scanner.
The SST-PFB-CLX-RLL DP supports a maximum of 125 slaves with a
maximum of 244 bytes of input data and 244 bytes of output data per slave
and it operates on all Profibus data rates up to 12 Mbps. As a Master, it
supports up to a maximum of 1984 bytes of input data and 1968 bytes of
output data within four I/O pages. The SST-PFB-CLX-RLL can act on a
PROFIBUS network as a DPV1 Class 1 & Class 2 master via generic CIP
messages (manages up to 16 simultaneous Class 1 commands and up to 16
simultaneous Class 2 commands and up to 32 simultaneous Class 2
connections). The module can also act as a DPV0 slave.
