“Remote Access 2.0” Remote Login
The core network information needs to be entered from
the appropriate tab on the system settings (see right).
This will ensure that there exists proper connectivity to
activate and use the EZAccess installation for the given
HMI as well as for the communications required for the
MODBUS TCP slave features (see previous section for
details on the register assignments for each sensor).
The network used can be either public node or else be
located on a subnet behind a firewall.
It is possible to remotely access the controller that has
been properly setup for EZAccess 2.0 from a Windows
PC, smartphone running iOS or Android as well as any
tablets that are also running iOS or Android. This
manual will focus on remote access from a Windows
PC. Please install the apps on your smartphone or
tablet and follow the provided instructions if you wish
to access from one of these devices.
For your convenience the most current version of the
EZAccess Setup & VNC Viewer for Windows at time of
dispatch is provided on the USB flash drive connected
to your HMI (see screenshot to the top on the right).
Please install these two software on the Windows
machine from which you wish to remotely access your
controller and setup the path of the VNC viewer.
The most current version can be downloaded directly
from Maple Systems and Real VNC websites:
https://www.maplesystems.com/SupportCenter/index.htm

Each controller can be assigned an HMI name. This is
what will appear when you login via the EZ Access
Windows application and must choose the machine to
which you will connect. In the example to the right the
HMI in question has been named as “3 Channel HiQDT
Controller”. For your field installation the most
descriptive name is recommended for ease of deciding
which machine you desire to remotely access.
Clicking on the appropriate icon will load the VNC
session. Click on the VNC session and follow the on-
screen instructions. The password to be entered is the
one that is set from the onscreen menu with the default
value being “111111”. The password for the local
machine can be changed from the appropriate onscreen
tab (see screenshot to right for visualization purposes).
