1 Task
Remote access is used to its full extent when you can use the same functions as if
you were standing right in front of the operator panel. Using existing hardware such
as your smartphone, tablet or standard notebook enables you to achieve the
greatest possible flexibility.
Apart from all the advantages remote access provides, you still need to be aware
of the hazards such an intervention may involve.
In most cases, the user remotely accessing the plant cannot see what is happening
in the plant at the moment of access. The intervention must not put the staff on site
or the plant at risk. To this end, it is important that you lock certain functions (e.g.,
manual control of a gripper) for the remote maintenance user. In addition, the staff
on site should be informed of an intervention and be able to stop it at any time if
necessary.
Moreover, it must be ensured that only authorized persons are provided with
access to the plant. Unfortunately, total network security cannot be guaranteed.
Therefore, it makes sense to inform the staff not only of the fact that a remote
maintenance user is accessing the operator panel, but also of who this is.

***************************************************************
of third-party intervention, connect your Sm@rtClient, a tablet with the SIMATIC
WinCC Sm@rtClient app in the above figure, to the SIMATIC HMI operator panel
using VPN.
The "Sm@rtServiceMonitor" tool is used to check the Sm@rtClient connections to
the operator panel. The IP addresses of the devices accessing the operator panel
are stored in internal WinCC tags for further processing. This allows you to check
who is currently accessing the operator panel at any time and, if necessary,
terminate remote access.
Advantages
The solution presented here offers the following advantages:
Flexibility through a variety of Sm@rtClient solutions
–
–
–
–
The Sm@rtClient app for Android and iOS enables you to access the
Sm@rtServer from mobile devices such as smartphones or tablets.
The Sm@rtClient Viewer enables you to access the Sm@rtServer from a
programmer or another standard PC.
The Sm@rtClient View WinCC control enables you to access the
Sm@rtServer via a WinCC Runtime Advanced station.
Internet Explorer enables you to access the Sm@rtServer from any PC.
The operator panel layout is represented by the Sm@rtClient app and the
Sm@rtClient Viewer and you can use, for example, keyboards
Up to four Sm@rtClients per WinCC Runtime Advanced station are possible
simultaneously (number depends on the device, see 5)
Operator actions are displayed on the device on site; i.e., an employee on site
can follow your operator steps

3 Principle of Operation

3.1
Principle of Operation
Sm@rtServer
The WinCC Sm@rtServer option enables operator control and monitoring of
operator panels via the intranet/internet. The Sm@rtServer provides its user
*******************************************************@rtClient,for
example a standard PC, a smartphone or another SIMATIC HMI Panel. The
Sm@rtClient concept is not only used for operator control and monitoring when
performing service jobs, it can also be used for large, geographically distributed
machines and plants. The mobile end use option makes this solution also suitable
for commissioning as you can move around the entire plant, regardless of the
operator panel's place of installation.
3.2 Application example
The "Sm@rtServiceMonitor" tool is used to check the Sm@rtClient connections to
a WinCC Runtime Advanced PC station. The IP addresses and the number of
devices accessing the operator panel are stored in internal WinCC tags for further
processing (VncClient1, VncClient2, VncClient3, VncClient4 and
VncConnectionCount).

SOAP web service
The SOAP (Simple Object Access Protocol) web service is used for writing the
tags. The operator panel provides this service via the integrated web server. It can
be used to access the HMI Runtime tags from external applications. Using the
SOAP service requires a web user with the appropriate permission on the operator
panel (see chapter 4.2.4 Operator panel settings).
Sample project
In the event of a value change of one of the tags, "VncClient1", "VncClient2",
"VncClient3" or "VncClient4", the "CheckConnections" script is called.
This script first checks what has changed compared to the previous cycle.
If a user is logged in to the operator panel on site and a new Sm@rtClient
connects, a message appears on the operator panel. This message is displayed for
a defined time and enables the operator on site to directly terminate the incoming
connection. (see chapter 5.2 Sample project). The remote operator cannot access
WinCC Runtime Advanced until this time has elapsed. In the sample project, the
default setting for this time is 10 seconds; however, you can change this setting
(see chapter 6 Additional Notes).
As long as (at least) one Sm@rtClient connection to the operator panel is active,
this is indicated by a flashing button. Clicking this button allows you to terminate
the connections at any time.

Remote Access to Runtime Advanced - Sm@rtServer

1 Task
Remote access is used to its full extent when you can use the same functions as if
you were standing right in front of the operator panel. Using existing hardware such
as your smartphone, tablet or standard notebook enables you to achieve the
greatest possible flexibility.
Apart from all the advantages remote access provides, you still need to be aware
of the hazards such an intervention may involve.
In most cases, the user remotely accessing the plant cannot see what is happening
in the plant at the moment of access. The intervention must not put the staff on site
or the plant at risk. To this end, it is important that you lock certain functions (e.g.,
manual control of a gripper) for the remote maintenance user. In addition, the staff
on site should be informed of an intervention and be able to stop it at any time if
necessary.
Moreover, it must be ensured that only authorized persons are provided with
access to the plant. Unfortunately, total network security cannot be guaranteed.
Therefore, it makes sense to inform the staff not only of the fact that a remote
maintenance user is accessing the operator panel, but also of who this is.

***************************************************************
of third-party intervention, connect your Sm@rtClient, a tablet with the SIMATIC
WinCC Sm@rtClient app in the above figure, to the SIMATIC HMI operator panel
using VPN.
The "Sm@rtServiceMonitor" tool is used to check the Sm@rtClient connections to
the operator panel. The IP addresses of the devices accessing the operator panel
are stored in internal WinCC tags for further processing. This allows you to check
who is currently accessing the operator panel at any time and, if necessary,
terminate remote access.
Advantages
The solution presented here offers the following advantages:
Flexibility through a variety of Sm@rtClient solutions
–
–
–
–
The Sm@rtClient app for Android and iOS enables you to access the
Sm@rtServer from mobile devices such as smartphones or tablets.
The Sm@rtClient Viewer enables you to access the Sm@rtServer from a
programmer or another standard PC.
The Sm@rtClient View WinCC control enables you to access the
Sm@rtServer via a WinCC Runtime Advanced station.
Internet Explorer enables you to access the Sm@rtServer from any PC.
The operator panel layout is represented by the Sm@rtClient app and the
Sm@rtClient Viewer and you can use, for example, keyboards
Up to four Sm@rtClients per WinCC Runtime Advanced station are possible
simultaneously (number depends on the device, see 5)
Operator actions are displayed on the device on site; i.e., an employee on site
can follow your operator steps

3 Principle of Operation
3.1 Sm@rtServer

3.1
Principle of Operation
Sm@rtServer
The WinCC Sm@rtServer option enables operator control and monitoring of
operator panels via the intranet/internet. The Sm@rtServer provides its user
*******************************************************@rtClient,for
example a standard PC, a smartphone or another SIMATIC HMI Panel. The
Sm@rtClient concept is not only used for operator control and monitoring when
performing service jobs, it can also be used for large, geographically distributed
machines and plants. The mobile end use option makes this solution also suitable
for commissioning as you can move around the entire plant, regardless of the
operator panel's place of installation.
3.2 Application example
The "Sm@rtServiceMonitor" tool is used to check the Sm@rtClient connections to
a WinCC Runtime Advanced PC station. The IP addresses and the number of
devices accessing the operator panel are stored in internal WinCC tags for further
processing (VncClient1, VncClient2, VncClient3, VncClient4 and
VncConnectionCount).

SOAP web service
The SOAP (Simple Object Access Protocol) web service is used for writing the
tags. The operator panel provides this service via the integrated web server. It can
be used to access the HMI Runtime tags from external applications. Using the
SOAP service requires a web user with the appropriate permission on the operator
panel (see chapter 4.2.4 Operator panel settings).
Sample project
In the event of a value change of one of the tags, "VncClient1", "VncClient2",
"VncClient3" or "VncClient4", the "CheckConnections" script is called.
This script first checks what has changed compared to the previous cycle.
If a user is logged in to the operator panel on site and a new Sm@rtClient
connects, a message appears on the operator panel. This message is displayed for
a defined time and enables the operator on site to directly terminate the incoming
connection. (see chapter 5.2 Sample project). The remote operator cannot access
WinCC Runtime Advanced until this time has elapsed. In the sample project, the
default setting for this time is 10 seconds; however, you can change this setting
(see chapter 6 Additional Notes).
As long as (at least) one Sm@rtClient connection to the operator panel is active,
this is indicated by a flashing button. Clicking this button allows you to terminate
the connections at any time.

If a user has logged in to the operator panel and a Sm@rtClient connects to the
Sm@rtServer, this user interface appears.
A ten-second time window starts, in which the user can decide whether the
connection may be established. An I/O field (1) displays the remaining time.
The time can be set in the WinCC project. For details, see the Additional Notes
chapter.
The "Cancel" (2) button allows you to terminate the connection. Clicking the button
disconnects all connected Sm@rtClients.
The I/O field (3) displays the IP address of the newly connected client so that the
operator on site can decide whether this client gains access.
To allow the connection and to be able to access the operator panel, wait until the
time expires. Then the previous screen is activated and the locally logged in user is
logged out.
