Chapter 1
Features
Overview The MobileView™ 2711T family of human machine interface (HMI) devices
have a rugged design with features that include a 3-position enable switch, touch
and function keys, and stop push buttons(1). These features let you access the
safety system of a machine and the general interface to its control system.
There are two generations of MobileView 2711T terminals. First generation
terminals use a 20-pin connection cable with a silver connector to connect to an
IP20 junction box. Second generation terminals use a 22-pin connection cable
with a black connector to connect to one of two available IP65 junction boxes.
Because of the pin differences, you cannot mix components between generations.
A second generation MobileView terminal, cat. no. 2711T-T10I1N1-TC, is a
thin client model without an operating system but is set for PXE boot into a thin
client server. This terminal is configured to work with ThinManager® software.
To learn more about how to PXE boot into a ThinManager server, access the
Rockwell Automation Knowledgebase link at
https://rockwellautomation.custhelp.com/ and search for AID 1043685.
There are two IP65 junction boxes that work with second generation
MobileView terminals. One junction box has cord grip connections, and the
other junction box has M12 On-Machine™ connections. Both IP65 junction
boxes have LED lights and a status indicator bar on their front plate that can
signify different operating and error states.

• Verify that interrupted processes can be properly restarted after power failures
or power dips. Do not allow any dangerous operating conditions to occur, even
temporarily.
• In situations where faults that occur within the automation system could cause
personal injury or significant damage to machinery and equipment, take extra
safety measures to confirm that the system remains in an acceptable operating
condition.
• When applying functional safety, restrict access to qualified, authorized
personnel who are trained and experienced.
• Verify that unauthorized persons are not allowed to adjust settings or make
memory modifications that can lead to dangerous situations.
• Test the functionality of the E-stop button and enabling switch at least once
every six months.Verify that the machine or plant operation stops when the
button is pushed.
• If the MobileView™ 2711T terminal and controller do not communicate with a
point-to-point connection, then keypad data could transmit with a delay. An
Ethernet switch that is used between the MobileView 2711T terminal and
controller is recommended for a higher speed connection.
• When a MobileView 2711T terminal has been exposed to shock (for example, it
is dropped on the ground), test to verify that the E-stop button and enabling
switch still function properly.
• The USB port on the backside of the MobileView 2711T terminal is only for
maintenance. Do not operate the terminal while a USB drive is connected to it.
• Risk assessment and risk reduction are important precautionary measures for
machine safety. For more information, see ISO 12100.
ATTENTION: Personnel responsible for the application of safety-related
Programmable Electronic Systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the
system.

Safety Precautions and Elements Chapter 2
Power Supply All MobileView 2711T terminals meet the Safety Class III requirements for
electrical shock in accordance with EN 61131-2. See Appendix A for the DC
power supply requirements for a MobileView 2711T terminal, junction box, and
connection cable.
Specifications of power supply lines in the connection cablesare:
• Cross section: 26 AWG (0.126 mm2)
• Material: zinc-coated copper strand
• Line resistance: <136 Ω/km (<219 Ω/mi)
Enabling Switch
On the MobileView 2711T terminal, the enabling switch consists of a 3-position
operating element with two independent circuits.
Enabling Switch Connection Example with a Control Relay
Figure 3 on page 18 shows suggested wiring for the enabling switch with an
Allen-Bradley® safety control relay. If this wiring example is followed, then the
safety function meets Category 4, Performance Level e (CAT. 4, PLe) in
accordance with ISO 13849-1 or SIL 3 in accordance with EN 61508.
SHOCK HAZARD: Supply the MobileView terminaland junction box exclusively
from power sources with SELV or PELV circuit protection according to EN 61131-
2.
Only connect voltages and circuits that are separated from dangerous voltages (for
example, by means of sufficient insulation) to connections, terminals or interfaces
up to a rated voltage of 50V DC.
WARNING: The 24V DC power supply to the control cabinet or operator panel
must have a fuse that is rated 3.15A (max) and complies with UL 248.
Failure to install a fuse can result in fire from component failure.
WARNING: Only the operator of the enabling device on the MobileView 2711T
terminal is allowed in the dangerous area or zone.
The enabling switch is only suitable as a safety device if the operator of the enabling
switch on the MobileView 2711T terminal recognizes the dangerous situation and
reacts in time to avoid the danger.
Consider reduced speed of movements as a precautionary measure, which can be
done through the risk assessment of machinery.

• Only if both channels (CH1 and CH2) of the enabling switch are
activated ‘simultaneously’ do output contacts 13-14 and 23-24 close, and
output relays K1 and K2 energize.
• The output relays K1 and K2 do not energize if:
– Only one enabling channel is activated.
– The tolerance value for the simultaneity period is exceeded.
– The feedback control loop at S34 is open.
• If one enabling channel is released after being simultaneously activated, the
forced-guided output contacts 13-14 and 23-24 open, and output relays
K1 and K2 return to their initial position. The output relays only energize
again after both enabling channels have been released and operate
simultaneously again.
In this way, the enabling switches avoid the one single error that makes the
safety function inoperable. At the least, one error is recognized at the next
cycle.

Safety Precautions and Elements Chapter 2
Foreseeable Misuse of the Enabling Switch
Foreseeable misuse is when the enabling switch is modified so it stays in the
enabling position. The foreseeable misuse of the enabling switch must be
restricted. The following measures are recommended, which cause the machine
to stop in manual mode.
• Inquiry of the enabling switch when you turn on the machine/plant, and
inquiry of the enabling switch when you change the operating mode from
automatic to manual (the enabling switch must not be in the enabling
position).
• The enabling switch must be released within a defined time period and
pushed into the enabling position again, with the time length defined by
the activity.
Emergency Stop (E-stop)
Push Button
The E-stop push button of a MobileView 2711T terminal meets the
requirements of ISO 13850. The button must be designed as a Category 0 or
Category 1 emergency stop by the risk assessment for the machine. The
connection of the force-guided contacts to an appropriate monitoring system
must meet the safety level that results from the risk assessment of the machine.
See Risk Assessment of Machinery on page 20.
The E-stop has two potential-free, normally closed contacts to connect external
peripherals, a nominal operating voltage of 24V (safety low voltage in accordance
with EN 61131-2), and a maximum operating current of 500 mA at 24V DC.
WARNING: E-stop push buttons (red-yellow in color) that are not fully
functional can have fatal consequences. E-stop push buttons must be effective
under all circumstances in all operating modes of a machine or plant.
• When the E-stop push button is not wired into an emergency stop circuit, the
MobileView 2711T terminal must be stored where it is not visible to operators.
• The reset of an activated E-stop push button must not result in the uncontrolled
startup of machines or installations.
• The E-stop push button does not replace other safety devices or E-stop buttons
mounted directly on machines.
• Do not use MobileView 2711T terminals with red-yellow E-stop buttons in
applications where the terminal is plugged in and out of junction boxes frequently
or meant for temporary use. Only MobileView 2711T terminals with gray stop push
buttons are meant for these applications.
• Test the functionality of the E-stop push button at least once every six months.
Verify that machine or plant operation stops when the button is pushed.
• When a MobileView 2711T terminal has been exposed to shock (for example, it is
dropped on the ground), test to verify that the E-stop push button still functions
properly.

Risk Assessment of Machinery
For the risk assessment for the machinery, use the standards in ISO 12100, “Safety
of machinery - General principles for design - Risk assessment and risk reduction.”
Figure 3 on page 18 shows how a first generation MobileView 2711T terminal uses
an Allen-Bradley control relay with the enabling switches. The control system must
be designed for the safety level that results from the risk assessment of ISO 12100.
MobileView2711TTerminal
Operation
The MobileView 2711T terminal is a high-quality device that is equipped with
state-of-the-art electronics.
ATTENTION: To avoid malfunctions or damage through improper handling,
follow these instructions during operation.
• Do not operate the terminal if the cable is damaged or pinched.To avoid
damaging the cable, do not place the cable over or around sharp objects.
• When the terminal is not in use, hang the terminal on the mounting bracket
(ordered separately) or place inside a cabinet or enclosure.
• To avoid impact damage to the terminal, do not set the terminal on unstable
surfaces and keep the cable clear of high traffic areas.
~ If the terminal falls to the ground, verify that the emergency stop switch
and enabling switch remain operable before you use the terminal on any
machinery.
• To avoid damage to the operating elements, do not set the terminal on its
operating side.
• Do not set the terminal near heat sources and avoid direct sunlight.
• Do not expose the terminal to strong magnetic fields or excessive vibrations,
dust, or humidity.
• Use a soft, damp cloth with 50% water and 50% isopropyl alcohol to clean the
operating panel and operating elements. Do not use solvents, scouring agents,
or scrubbing sponges.
• Help prevent foreign objects or liquids from getting into the terminal. Check
the protective covers of the device regularly. Verify that all screws are firmly
tightened and that the housing and cable entrance are not damaged.
• Turn off the power supply before you remove the back cover of the MobileView
2711T terminal. When the back cover is removed, the terminal is sensitive to
electrostatic discharge (ESD).
• If the terminal exhibits any anomaly, have the unit thoroughly and fully tested
by the manufacturer or authorized repair dealer before you operate the
terminal again.
• Do not use sharp objects, such as a screwdriver, on the touch screen. Scratching
the surface of the touch screen can damage the display and compromise the IP
rating.
