Using companion specifications: Overview
Euromap 77 is described in the OPC UA XML file "Opc_Ua.EUROMAP77.NodeSet2.xml".
Note
Euromap 77, Euromap 83 and OPC UA for Devices (DI)
With Release Candidate 2, some of the Euromap definitions have been transferred from
Euromap 77 to Euromap 83. You will therefore also need to import the OPC UA server
interface of Euromap 83.
"OPC UA for Devices" is a generally applicable information model for the configuration of
hardware and software components. The information model also serves as the basis for
other companion standards and is therefore also imported.
The OPC UA XML files are available here:
Euromap77 (http://www.euromap.org/euromap77)
Euromap83 (http://www.euromap.org/euromap83)
OPC UA for Devices (https://opcfoundation.org/UA/schemas/DI/)
These XML files define an OPC UA interface of an injection molding machine that complies
with Euromap 77.
Using Euromap 77: Overview
To use Euromap 77, proceed as follows:
1. Generate an XML file by creating an instance of the type "IMM_MES_InterfaceType"
using the SiOME program.
How to proceed is described below in "Step 1: Create instances in SiOME".
2. In STEP 7 (TIA Portal), create PLC tags and server methods that correspond to the
instance of the type "IMM_MES_InterfaceType" (created in Step 1).
See below for information on how to proceed in "Step 2: Create PLC tags in STEP 7".
An example of OPC UA nodes and the corresponding PLC tags can be found in section
"Creating a server interface for companion specification (Page 218)".
3. In STEP 7 (TIA Portal), add a new server interface of companion specification type and
import the XML file you created in step 1.
The "Creating a server interface for companion specification (Page 218)" section
describes how to proceed.
4. Assign the OPC UA nodes of the new server interface to the corresponding PLC tags,
which you created in step 2.
The "Creating a server interface for companion specification (Page 218)" section
describes how to proceed.
