Configuring message classes

When loading AS messages to a SIMATIC S7-1500, WinCC automatically assigns a message class/message type with a corresponding setting to the messages.

Table 3-5

STEP 7 WinCC acknowledgment philosophy

Acknowledgment Acknowledgement “arrived”

Acknowledgement “left”

Without status “left”

No acknowledgement

Acknowledgement “arrived”



No acknowledgement

Information only

Acknowledgement “arrived”



Bold font = applicable

Normal font = not applicable

Note The message classes in TIA Portal should be adapted to the message classes in WinCC Configuration Studio, if possible. Thus, they could be assigned more easily in WinCC Configuration Studio after import.

It is helpful to distinguish the colors of the message types ("arrived", "left",...). Thus, the message type can be assigned more quickly and easily, e. g. in the AlarmControl.

3.3 Implications for project changes in the controller

If you want to modify the project on the controller side, you have to reload the AS symbols and messages via the context menu or using the import function. In this case, the properties of the AS symbols and messages are compared to the properties from the WinCC project.

If the AS symbol names or symbolic addresses do not match, the "AS Symbols" tab will be highlighted in red. If the AS messages have changed, they will be highlighted in red in the "AS Messages" tab. Tooltips with notes on possible causes are displayed.

Note TIA Portal automatically generates the symbolic addresses of the AS symbols. They depend on the corresponding AS symbol properties. Due to symbolic access, address changes in the CPU program will not affect the symbolic address.

3.4 Connection with absolute addressing

As of WinCC V7.2, you can use the communication channel "SIMATIC S7-1200, S7-1500 Channel" to establish a communication with non-optimized blocks.

For this, in TIA Portal, go to the properties of the block and uncheck the "Optimized block access" option in the "Attributes" tab.

Figure 3-3

To get the absolute address (offset), compile the block in TIA Portal.

Figure 3-4

Note As soon as you make any changes concerning the block (e. g. another input), the offset will not be displayed anymore. After recompiling, you can read it again.

For further information on creating tags, please refer to the manual

Import/export with TIA Portal

Note The process is only possible with absolute addressing. It is not possible to use symbolic addressing for this procedure. Symbolic addressing can only be exported as of V7.4 SP1.

The following restrictions exist:

No side-by-side installation with WinCC Professional (TIA Portal)

No measurement archives

No chronological messages

An export or import consists of two steps:

Export of the tags from TIA Portal

Import of the data via the WinCC Configuration Studio

Export procedure

Table 3-6

1. Create a new DB in TIA Portal and disable the optimized block access.

2. Compile the block to get the absolute addressing (offset).

3. Create a dummy HMI project (e. g. Basic Panel).

4. Use drag&drop to drag the block into a screen and set the access mode from “symbolic” to “absolute”.

5. Click the “Export” button to export the HMI tags.

3.5 Ensuring a better overview of numerous tags

In order to ensure a better overview of AS symbols, there are various options to adjust the different views. The methods described below will make it easier to handle the AS symbols and tags available. Moreover, prefixes can be used e. g. to summarize structures.

Search

The "Search" function can be used to limit the displayed AS symbols or tags to the desired area.

Figure 3-5

Find & Replace

The "Find and Replace" function can be used e. g. to include prefixes for certain blocks or structures in the name. Thus, you can define new search terms by means of which you can create the views you want for every single search.

Figure 3-6

Note After having read the tags again, all changes made by the "Find and replace" function have been overwritten and possibly have to be made again.

As of WinCC V7.4 SP1, you can set the Prefix / suffix for tags 5.1 as default value instead of using the "Find and replace" function.

4.1 System diagnostics

As of SIMATIC WinCC V7.4, the ActiveXControl "WinCC SysDiagControl" is available for system diagnostics. You can find it in the "Controls" toolbar.

Figure 4-1

For details about the configuration, please refer to the manual WinCC V7.4: Communication.

It indicates faults and errors of the SIMATIC S7-1200 and S7-1500 controllers. It provides an overview and thus allows rapid localization of error sources.

In the ActiveXControl, the following views are available:

Diagnostic overview Displays the status of the controller and its submodules for all available SIMATIC S7-1200/S7-1500 channels.

Detailed view Displays information on the selected controller.

Diagnostic buffer view Displays current data from the diagnostic buffer of the controller. Messages are only displayed if the AS messages are loaded from the controller and applied to WinCC.

You can use a C script or VB script (e. g. executed via a mouse-click on a button) to go from an AS message selected in the WinCC AlarmControl to the WinCC SysDiagControl. For this, the AS message already must have been loaded from the controller and applied to WinCC as messages.

In C:

SetPropChar(lpszPictureName,"<Name_SysDiaControl>").","NavigateTo",

GetPropChar(lpszPictureName,"<Name_AlarmControl>","DiagnosticsContext"));

In VBS:

ScreenItems("<Name_SysDiaControl>").NavigateTo =

ScreenItems("<Name_AlarmControl>").").DiagnosticsContext

Note Please note that toggling between the controls by means of a script is only possible for system messages.

Further information on this and on how to configure the control are available in the manual WinCC V7.4: Communication.

4.2 "Update" function

With SIMATIC WinCC V7.4, the "Update" function is available. After project changes on the controller side, symbolic addresses can change. You can use the "Update" function to read the AS configuration again. Moreover, it restores consistency by reassigning the symbolic addresses to the AS symbol names. The AS symbol name is taken as a reference. To use the function, the AS symbols and messages already must have been read and applied as WinCC tag or WinCC messages.

Note "Update" function not possible

Access rights changed If you disable the access rights of the AS symbols, these will not be accessible anymore for WinCC. Thus, "updating" is no longer possible as well. If, afterwards, you read the AS configuration again, the WinCC tags will be highlighted in red.

AS symbol names changed The "Read AS Symbols" function is based on the AS symbol name. If you change the AS symbol name and read the AS configuration again afterwards, "updating" will not be possible anymore. The changed AS symbol name will be available in WinCC as a new AS symbol and you have to apply it as a new WinCC tag. Delete the unused WinCC tag in the "Tags" tab.

For the following project changes on the controller side, the symbolic addresses of the AS symbols will change. Use the "Update" function.

Current CPU program has been replaced by an identical CPU program (or parts of it) from a reference project (project copy) and reloaded into the controller

Change of the data type of a CPU tag (also in the DB)

Note WinCC performs an automatic data type formatting between CPU data types and HMI data types. If you change the data type of a CPU tag, a data type change might affect the usage locations of the tag. Please note that adaptations might be necessary.

4.3 Connection-specific tags

To be able to monitor the connection status to the S7-1500, the following two @system tags are available.

"@<ConnectionName>@ForceConnectionState"

"@<ConnectionName>@ConnectionState"

"@<ConnectionName>@ForceConnectionState" tag

In the connection, create the "@<ConnectionName>@ForceConnectionState" tag to define the connection status between a WinCC station and S7-1200 / S7-1500:

"1": The connection is established.

If you configure "1" as start value, the connection to S7-1200 / S7-1500 will be

established when starting runtime.

"0": The connection is disconnected.

To ensure that the tag is initialized when starting runtime, assign an "absolute address" to the tag. Moreover, this tag must not be a binary tag.

"@<ConnectionName>@ConnectionState" tag

Determine the current status of the connection using the connection-specific tag "@<ConnectionName>@ConnectionState":

"1": The connection is ready for operation.

"0": The connection is interrupted or disconnected.

5.1 Prefix / suffix for tags

This section describes how to set the prefix/suffix as default value for tags for each connection.

Procedure

Table 5-3

No. Action

1. In the Configuration Studio, go to the Tag Management and select the connection for which you want to create a prefix or suffix.

2. Enter the desired prefix / suffix in the properties of the connection.

The prefix / suffix will be displayed exactly like you have specified it, i. e. it has to be entered including the desired separators.

3. Now, read the AS symbols via "AS Symbols" > "Read from AS".

4. Enable the "Access" option to ensure that a tag with prefix and/or suffix will be created.

Note If later on you want to use a prefix or suffix for tags that already have been used, it is necessary to remove the checkmark for the "Access" option and to set it again.

Alternatively, you can use the "Find & Replace" function to assign the prefix and suffix.

Notes If changes are made to the controller, it is absolutely necessary to execute the “Read from AS” command again.

If WinCC Runtime is stopped and the Tag Management is closed, symbolic addressing and the “AS Symbols” tab will not be displayed anymore. You can display both in the Tag Management again using the “Read from AS” command.

5.2 New features for AS messages

As of WinCC V7.4 SP1, messages of the S7-1500 can be applied automatically after message changes. For this, set the checkmark for the "Auto Update" option at connection level in the "Alarm logging".

Figure 5-1

Note If you have already read the AS messages manually using "Read from AS", first delete the read messages in WinCC. Then, you can set the checkmark for the "Auto Update" option to ensure that the messages are not available twice.

6.3 Channel diagnosis "SIMATIC S7-1200, S7-1500 Channel"

For channel diagnosis of the communication channel "SIMATIC S7-1200, S7-1500 Channel", WinCC offers the following tools:

"Status - Logical Connections" function

ActiveXControl "WinCC Channel Diagnosis Control"

"Channel Diagnosis" program

The channel diagnosis allows a status request of the current connections.

"Status - Logical Connections" tool

The "Status - Logical Connections" function is a tool integrated in SIMATIC WinCC. To use it, you have to start the runtime. You can call the function via the menu "Tools > Connection Status".

The tool displays the most important parameters of all connections that have been created. This includes the following connection parameters:

Connection ID

Name of the connection

Current status of the connection

Number of tags read

Number of read requests

Number of tags written

Number of write requests

You can cyclically update the connection parameters. You will find the necessary setting in the bottom part of the dialog.
