Set up your ControlLogix environment

To set up your ControlLogix environment
  1. Set up the ControlLogix chassis.
  2. Insert the ControlLogix controllers into the chassis.
    You can connect to five controllers in a single ControlLogix chassis.
  3. Power on the system.
  4. Configure the ControlLogix devices.
For details, refer to the ControlLogix Chassis and ControlLogix Controller documentation.
FactoryTalk Historian ME can connect to:
  • The controllers in the same chassis in which it is placed.
  • The controllers placed in a remote chassis (ControlLogix and controllers from the CompactLogix 5370 family).
    TIP:
    For more information about the supported controllers refer to FactoryTalk Historian ME Release Notes.
If FactoryTalk Historian ME must connect to data in other chassis hardware such as non-ControlLogix or third-party controllers, you can configure a ControlLogix controller to act as a data concentrator in the same chassis. This controller can then be configured to expose the data from the remote controllers to the FactoryTalk Historian ME. However, it is critical to consider the increased load that an extra data server will introduce in a ControlLogix system when configuring the data collection.
FactoryTalk Historian ME's data gathering and trending impact on a Logix controller is dependent on the ControlLogix system configuration. This includes the available Logix controller bandwidth as well as the number of tags being trended and the sample period. The Logix controller bandwidth is determined by the controller type, free memory, the system overhead time slice, and user application programs.
Trending is a higher priority task in the Logix controller than in user application programs. Trending too many tags at a too low sample period can impact the Logix controller's ability to execute user application programs and cause task overlaps. When using FactoryTalk Historian ME, you must ensure that there is sufficient Logix controller bandwidth to service trending without negatively impacting user application programs.
