RSLinx Classic Gateway

Hello All,

What is difference between Factory Talk Gateway OPC & RSLinx Classic Gateway OPC Server ?

Does Factory Talk Gateway OPC Server support PLC5 on DH+ network ? I am planning to stat OSI PI Historian Project and need to pick which OPC server I should choose tp push data from PLC,CompactLogix, ControlLogix PLCs to Pi.

Thanks, Raj

Hi Raj and welcome back to the forums. Here is a quick little comparison.

RSLinx Classic vs. RSLinx Enterprise vs. 3rd Party OPC

RSLinx Enterprise:

• RSLinx Enterprise is optimized to provide the best performance for large numbers of clients (more than 10), and large number of tags (more than 10,000), even if located on the same computer as the Historian SE Server.

• Can communicate with SLC/PLC/CLX controllers (excluding PLC-2, PLC-3 and PLC-5/250).

• Can serve OPC data with the addition of FactoryTalk Gateway.

• Preferred Historian SE Live Data Server to Rockwell controllers.

RSLinx Classic:

• On applications containing more than 10,000 active tag s on scan, may require its own dedicated host computer. This is dependent on hardware performance.

• Can communicate with SLC/PLC/CLX controllers (including PLC -2, PLC-3 and PLC-5/250)

• Complex communication routing. Protocol changing (ex. Ethernet to DH+).

• Can serve OPC data.

• RSLinx connections to processors on an Ethernet network.

3rd Party OPC servers

• For applications containing more than 10,000 active tags on scan, may require its own dedicated host computer. This is dependent on hardware performance.

FactoryTalk Gateway

• FactoryTalk Gateway is an OPC server that enables OPC clients to connect to FactoryTalk applications that contain RSLinx Enterprise and Historian SE servers. By doing so, they can access tag data within those applications.

• FactoryTalk Gateway Distributed is for FactoryTalk network applications.

• Only one FactoryTalk Gateway can be installed per computer.

• Multiple FactoryTalk Gateways can point to a single FactoryTalk application.

• FactoryTalk Gateway can only point to a single FactoryTalk application at a time.

• FactoryTalk Gateway can communicate to as many unique tags as licensed.

• 20 remote OPC clients have been formally tested and validated against FactoryTalk Gateway.

It might be best to contact your local Rockwell rep to find a solution that is the best fit for your particular application.
