Security informa-tion

Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks. In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions only form one element of such a concept. Customer is responsible to prevent unauthorized access to its plants, systems, machines and networks. Systems, machines and components should only be connected to the enterprise network or the internet if and to the extent necessary and with appropriate security measures (e.g. use of firewalls and network segmentation) in place. Additionally, Siemens’ guidance on appropriate security measures should be taken into account. For more information about industrial security, please visit http://www.siemens.com/industrialsecurity.

Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly recommends to apply product updates as soon as available and to always use the latest product versions. Use of product versions that are no longer supported, and failure to apply latest updates may increase customer’s exposure to cyber threats. To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed under http://www.siemens.com/industrialsecurity.

1 Introduction

The HMI Toolbox of the Siemens Industry Online Support provides a variety of useful tools that makes your everyday work easier.

The HMI Toolbox comprises tools for the subject areas:

Time functions

Each subject area has its own documentation. Additionally, there is an example projects available that shows how to use the tools.

Application example

"Example project for WinCC V7.4"

Was created with STEP 7 Professional / WinCC Advanced V7.4. A PC station with WinCC V7.4 and an S715163 PN/DP as controller was used as HMI operator panel.

This document describes the functioning and implementation of the tools for the "Time functions" subject area.

The "Time functions" subject area comprises three different tools:

2 Alarm

2.1 Solution

2.1.1 Description

With the alarm you can be reminded of a certain event via a screen in Runtime at a fixed point in time.

The time (hh:mm:ss) is entered via three I/O fields directly in the screen. Actuate the button to enable the alarm.

The controller compares the current time with the time of the alarm and triggers an alarm when the set time is reached.

In the status bar you can see when the alarm expires. Click on the status bar to acknowledge the alarm.

2.1.3 Data types and function blocks used

FC "LGF_DTL_toString"

The "LGF_DTLtoString" function block is taken from the "Library of general functions (LGF) for STEP 7 (TIA Portal) and S7-1500". This block converts a date component of the DTL data type into a character string of the string format.

Further information on this function block is available in the following entry ID 109479728.

FB "LHmiTime_Alarm"

The "LHmiTime_Alarm" function block compares the embedded alarm time with the system time. If both match, the function block sets an "elapsed" alarm status and returns the time "elapsedTime" if an error occurs.

No. Action

1. Download the "109749914_LHmiTime_LIB_V14.zip" library and unzip the file.

2. Open your STEP 7 configuration.

Open the "Global libraries" tab in the "Libraries" task card.

3. Click the second icon from the left to open "Global library".

4. Select the "109749914_LHmiTime_LIB_V14.al14" file and click the "Open" button to open the library.

5. Open the "Master copies" folder of the library. Drag the "LHmiTime_CommDB" data block into the "Program blocks" folder of your controller.

All tags that are required for the alarm have the prefix "alarm". Delete all other tags from the "LHmiTime_CommDB" data block.

6. Open the "Types" folder of the library and drag the function block "LGF_DTLtoString" and "LHmiTime_Alarm" to your controller.

Note

You only require the "LGF_DTLtoString" function block if it is not yet integrated in your project.

3.1 Solution

3.1.1 Description

You can monitor and record the duration of your plant’s production steps, using the stopwatch.

The stopwatch is started via the "START" button and stopped via the "STOP" button. The controller takes on the calculation of the rounds.

The stopwatch can save up to 5 rounds and output them on your HMI operator panel. The rounds are recorded, using the "Round" button. Once five rounds have been recorded, the stopwatch stops. You can reset the times for stop and rounds, using the "RESET" button.

4 Timer

4.1 Solution

4.1.1 Description

The timer reminds you of an event after the lapse of a defined runtime.

By default, the timer offers five runtimes (1 min, 2 min, 5 min, 10 min, 15 min). Set the runtime by actuating the appropriate button.

The controller starts a timer with the specified runtime and triggers an alarm once the time has lapsed.

In the status bar you can see when the timer has expired. Click on the status bar to reset the timer.

FC "LGF_DTLtoString"

The "LGF_DTLtoString" function block is taken from the "Library of general functions (LGF) for STEP 7 (TIA Portal) and S7-1200 / 1500". This block converts a character string of the string format with date components into the DTL data type.

Further information on this function block is available at the following link: 109479728.

FB "LHmiTime_Timer"

The "LHmiTime_Timer" function block starts a timer with the "duration" runtime. Once this has lapsed, the function block sets an alarm status "elapsed" and returns the current system time "elapsedTime".
