1-2 Introduction to InView Connectivity
Controller Based
Communications InView controller based communication can be used to trigger
messages and update variables on an InView display. InView
communication allows for connection into new and existing control
environments.
Point-to-point RS-232 Serial Communications
Point-to-point serial communications allow the use of a controller to
trigger messages and update variables on an InView display. RS-232
serial communications support a single display connection with a
limited distance of 15.24 m (50 ft).
RS-232 Serial Communications
Multi-drop RS-485 Serial Communications
RS-485 Multi-drop networks allow for Serial communications from a
single controller to multiple InView displays. With the use of an AIC+
(RS-232 to RS-485 converter) or a 2706-P9 type InView display, you
can daisy chain multiple InView displays off channel zero of an
Allen-Bradley controller. Each InView display can have a unique
address, allowing for individual display control over the network with
a maximum distance of 1219 m (4000 ft).
