RSLinx – Training Guide 11
RSLinx Lite, RSLinx OEM, RSLinx Professional, RSLinx SDK, RSLinx Gateway
What’s the difference?
RSLinx is available in versions to meet the cost and functionality requirements of many
different applications. Depending on the version you are running, some functionality may
or may not be operational.
To know which version you are running, read RSLinx main title bar text
(the line of text at the very top of the main window). If you are running the Lite or OEM
version, some of the features documented in the online help file may not be enabled.
The following explains the main differences between the different versions of RSLinx:
We’ve packaged RSLinx to provide the best cost/functionality trade-off to address
different market segments:
• RSLinx Lite – Only used when bundled with other Rockwell Software products
that use RSLinx as their communication interface to plant floor devices. No
external interfaces are provided for DDE, OPC or custom ‘C’ applications.
• RSLinx OEM – Intended for use with third party HMI’s or custom applications.
Provides complete driver support for Allen-Bradley devices and networks.
We expose our AdvanceDDE interface for DDE messaging, OPC COM interface
for local
OPC connectivity and runtime support for custom applications
developed with the RSLinx SDK.
• RSLinx Professional – Full-featured version. Includes all the functionality in
RSLinx OEM plus additional features such as: DDE formats (XL_Table,
CF_Text) for Microsoft Office or standard DDE client applications, FastDDE for
Wonderware clients, and an OPC Automation interface for local
OPC
connectivity.
Note: An RSLinx package that has lost its activation will revert back to RSLinx Lite.
Some applications, such as RSView32, can NOT communicate to tags or other
PLC data using only RSLinx Lite.
Ensure the activation files are safeguarded to protect against loss or damage.
