Application Examples - Rockwell Automation Allen-Bradley MobileView Terminal Application Technique

Using a MobileView Terminal With Multiple IP20 Junction Boxes
Stratix Switch
Stratix switch features are used by Logix safety controllers to check and verify that there is an active link between local
ports and the junction box. The MobileView application can detect which junction box is connected by monitoring the
presence bit.

Application Examples

The following application examples offer guidelines to connect and disconnect a MobileView terminal to multiple IP20
junction boxes in three different operating conditions:
All junction boxes are in a hazardous area
The junction boxes are in hazardous and non-hazardous areas
All junction boxes are in a non-hazardous area
In these examples, Area 1 and Area 2 are hazardous areas, while Area 3 is non-hazardous. A MobileView terminal with a
gray stop button (cat. nos. 2711T-F10G1N1 or 2711T-T10G1N1) and MobileView IP20 junction boxes must be used
in this application.
IMPORTANT In these examples, the MobileView terminal is not always connected to a junction box, as required in Chapter 2, Safety
Precautions and Elements, of publication 2711T-UM001.
Application 1: All Junction Boxes Are in a Hazardous Area
When a junction box is in a hazardous area, one or more emergency push buttons must be installed near the junction box.
The bypass operation is managed by a coded key (two position key lock switch 800FM-KM21).
Outside the hazardous area (access protected by safety gates with an interlocked switch), there must be a defined
procedure to request access (for example, with a push button or with a virtual button on the operator panel) that can be
handled by the GuardPLC™
