Allen-Bradley ControlLogix Ethernet Driver Help

Note: It appears that Logical Blocking is most optimal for the given application.

Optimizing Channel Communications

Channel communications can be optimized by moving tags for Logical Blocking in one device and tags for Logical

Non-Blocking in another. This is called tag division.

Logical Blocking (Device 1)

ProcessPID

OverflowCounter

Logical Non-Blocking (Device 2)

FlowRate

ValveOpen

InProcess
