For communications with Allen-Bradley local and remote devices—particularly with
Logix5000 controllers—RSLinx Enterprise is the recommended data communications
software for FactoryTalk View applications.
When to use RSLinx Classic
RSLinx Enterprise is the preferred choice when using Logix controllers, but there are
some cases where Linx Classic must be used.
For example, install and use RSLinx Classic to serve data through DH+ (Data Highway +)
networks, to support complex bridging and routing, and to support unsolicited messaging
from a controller to RSLinx.
With RSLinx Classic, you can also create alias topic shortcuts and perform online tasks
such as uploading and downloading RSLogix 5000 files.
Communicating with third-party local and remote devices
For communications with non-Allen-Bradley local and remote devices, FactoryTalk
View SE supports OPC, a protocol used to connect to communication devices via vendor-
specific OPC servers.
OPC enables FactoryTalk View to act as a client to other OPC servers. This means that
FactoryTalk View can use third-party OPC servers to retrieve tag values from third-party
controller devices, such as Siemens or Modicon.
FactoryTalk View supports the OPC-DA(Open Platform Communications Data Access)
2.05a specification.
Step 5: Install the necessary activation keys
The types of product licenses you require depend on the software you have installed, and
how you intend to use it.
For information about the types of activation you might need, and how to install activation
keys, see the FactoryTalk View Site Edition Installation Guide.
Running FactoryTalk View SE without activation
The FactoryTalk View SE and RSLinx software you install must be licensed for full use.
If for some reason activation is unavailable, the software can run unlicensed for a grace
period of up to seven days. This provides time to correct any problems, without disrupting
critical applications.
If activation is restored within the seven days, normal operations will resume. If activation
remains unavailable when the grace period expires, the FactoryTalk View SE software
will run in demo mode.
