Rockwell adds communication module to operator interfaces and industrial computers

Rockwell Automation has added a ControlNet scheduled communications module to its Allen-Bradley PanelView Plus operator interface terminals and VersaView CE industrial computers. This module provides deterministic, repeatable communication that allows users to accurately predict data transmission and guarantee its arrival at the same time, every time.

Unlike the ControlNet unscheduled communications, which use leftover bandwidth as it becomes available, ControlNet scheduled takes priority placement on the network's bandwidth.

PanelView Plus terminals with ControlNet scheduled communications can support more information than older PanelView models, according to the company, with a messaging capacity of up to 6,144 bytes of input and output data to Logix, PLC-5 and SLC processors.
