Overview of Rockwell protocol

The following image shows the data source input window for the Rockwell protocol:

Rockwell data source parameter

In order to connect a Rockwell device, you need to select the Rockwell protocol and enter the following data source parameters:

Parameter	Description
CPU type	Shows available CPU types: COMPACT_LOGIX OTHER_CPU Currently not available: CONTROL_LOGIX FLEX_LOGIX MICRO_LOGIX SOFT_LOGIX PLC5 SLC500
IP address	IP address of the Rockwell controller.
Route parameters	Here you can define the routing path parameters - like rack, slot, node, and/or ControlNet port numbers - needed to access the controller (default: 1,0).

Rockwell data point parameter

In order to collect the data of your Rockwell device, you must add new data points.

The following table shows the data point parameter:

Parameter	Description
Data Type	Data type supported by backend (e.g. INT). STRING data type is currently not supported.
Tag	Name of the tag that has to be recorded.

Parameter

Description

Data Type
