How to Connect WinCC V6 to the InGear OPC Server
The purpose of this paper is to demonstrate how to connect Siemens WinCC V6 to theINGEAR OPC Server. This example uses the INGEAR AB OPC Server connecting to aControlLogix, but the same steps are used to connect to other PLCs supported by the INGEARAB OPC Server or to any of the other INGEAR OPC Servers.
The information provided here is not a substitute for your WinCC V6 documentation. We arecovering how to do this in order to show a complete connection, not to provide comprehensivetraining on how to build WinCC V6 screens.
1) Configuring the INGEAR OPC ServerOpen the OPC Server from the Windows Start menu as shown below.
When the INGEAR AB OPC Server opens you will see the Quick Start dialog below. Detailson configuring the other INGEAR OPC Servers can be found in their respective help files.Tags dont have to be entered into the OPC Server as done in this example. Dynamic tags canbe added from within WinCC as long as a Driver, (under EditComm Settings on theINGEAR AB OPC Server Menu) and Device are configured first in the INGEAR OPC Server.
The use of dynamic tags is covered at the end of this document.

How to Connect WinCC V6 to the InGear OPC Server
Click on the OK button on the Quick Start Configuration screen.When configuring a ControlLogix you can import the tags from the AB RSLogix 5000 PLCprogramming software if you have saved this file as an .L5K file. The L5K file can be createdin RSLogix 5000 by choosing File, Save As and choosing to save your project as a L5K
extension. If youre connecting to something other than a ControlLogix then click on the QuickStart button as shown below.
Once you click on Open L5K you can browse to the L5K file as seen below.
Click Open and the OPC Server will begin importing the tags. The L5K Import Status willpop-up as shown below while the tags are imported.

How to Connect WinCC V6 to the InGear OPC Server
When the OPC Server is done importing the tags, the name of the device as pulled from theL5K file can be seen in the tree window to the left as seen below. In this case the device iscalled SWTBtestCPU. You can click on the + sign to expand the tree and see all the tags andgroups imported from the L5K file. Tag groups and tags that wont be used can be deleted.
The first thing to do is to check to make sure the right IP address was imported. This is done bygoing to the Edit menu and choosing Comm Settings as shown below.

How to Connect WinCC V6 to the InGear OPC Server
When entering Dynamic tags only without the L5K import, selecting EditComm Settings
would be the first step to configure a Driver so that the OPC server knows how it will
communicate to your PLC.
The Driver Selection dialog will open showing the configured drivers. If your IP address is
shown correctly simply click Cancel. If its wrong or you are not sure click on Configure. Youcan change your IP address to the correct one and close the dialog.
When manually configuring the Driver because you are using Dynamic Tags or manually
setting up the OPC server for some other reason, you will click on the drop-down under
Supported Drivers, choose the driver for the type of connection you are using and click on the
Add button. Once a Driver is installed you can go to Add and choose NewDevice to manually
add a device as shown below or Click on the Quick Start Configuration to guide you through.

Next we will check the device configuration by right clicking on the device name as shownbelow (SWTBtestCPU in our case) and choosing Properties.
When manually configuring the OPC Server or doing Dynamic tags we suggest that you add at
least one tag to check communications. This would be done by choosing New Tag from this
same menu above. The Tag Properties window will open as shown below. See the INGEAR
OPC Server help file or press on the Help button shown in the InGear OPC Server for detailsabout these settings.

How to Connect WinCC V6 to the InGear OPC Server
The Device Properties window will open as shown below. Check to make sure the Driver thatwe configured above is selected. Verify that the PLC Node is the same as the Slot number thatyour ControlLogix CPU is located in. Check the INGEAR AB OPC Server help file if yourControlLogix is on a different rack from the Ethernet module you are using. In this case a routepath will have to be entered and specifics on creating a route path for various types of
configurations, including ControlLogix Gateway, are included in the INGEAR AB OPC Serverhelp file. The help file is accessible from the Help button on the Device Properties dialog asshown below.
Once these items have been verified click OK.
When Manually configuring or doing Dynamic tag this screen will need to be configured as
discussed above. The Driver in the drop down will need to be selected (the available selections
will depend on what you have configured for Installed Drivers under the EditComm Settings
options) as well as the PLC type by selecting the appropriate radio button. See the help file for
more information about the PLC Node address or ControlLogix route address.
The final part of configuring the OPC Server is to test the Connection. This can be done now or
at a later time when you are connected to the PLC. This next step can be done as long as atleast one tag is configured in the OPC Server. As previously stated, we suggest having a singletag configured just for basic success/fail testing, even if all the other tags are addedDynamically from WinCC.

More detailed information on the syntax of Dynamic tags is show below.
Dynamic Tags Fully Qualified Path Syntax
The client specifies the Dynamic Tag in its OPC Item Address field in WinCC flexible
Syntax: ..@|DATA_TYPE,
. This is the name of the Device to receive the dynamic tag. The devicemust exist in the OPC Server Project Workspace
. (optional) A device subgroup may be specified as part of the dynamictag. The device subgroup must exist in the OPC Server ProjectWorkspace
This is the name of the tag the client will dynamically create. If the namealready exists in the OPC Server Workspace, the existing tag is used,otherwise a new tag is created.
@ This is the data source of the tag. If the Device is a ControlLogix, this isthe atomic name of the tag. If the Device is a PLC / SLC / Micrologix,this is the data table file address
|DATA_TYPE This is the data type of the tag. Valid types are VT_I1, VT_UI1, VT_I2,VT_UI2, VT_I4, VT_UI4, VT_R4, VT_BSTR
, (optional) This is the length of the tag, and is used to specify thenumber of ASCII characters of the tag is a VT_BSTR type or the numberof elements if the tag is a VT_ARRAY.
