Configuring process data

You can configure the process data to be transferred via PROFINET. Various module types, e.g. Byte, Word, DWord or Real are available in various lengths. The module types are created in the tree view of the System Manager under the API (Application Process Identifier).

Requirements:

  • A PROFINET slave added in TwinCAT

Configure the process data as follows:

1. Right-click on the API in the tree view on the left.
2. Click on Add New Item in the context menu.
Configuring process data 1:
3. Select the required module and enter the number of modules in the field Multiple. TwinCAT uses the GSDML file under: C:\TwinCAT\3.1\Config\Io\Profinet
Configuring process data 2:
  • The required number of modules are created under the API (Application Process Identifier). In the next step you can either rotate the process data, create a virtual slave or create a PLC project.
