Object: Simulation Interface

The Simulation Interface object is located below the application. It provides a configurator for the simulation interface and for the simulation broker.

Tab: Configuration

Simulation enabled

: The application connects to the simulation tool. (Consequently, the physical I/Os are decoupled.)

: The application uses the physical I/Os.

Table 2. Simulation Options

Entire I/O image	The entire I/O image is sent and received. It is independent of whether the I/Os are mapped or not.
Mapped I/O signals only	Only the assigned I/O signals are sent and can be received.

Table 3. IP Settings

`Publisher Multicast/Unicast IP`	IP address for the publication of output of the I/O mapping Make sure that this address range does not match other IT/OT systems in the shared environment.
`Subscriber Multicast IP`	IP address with which the inputs of the I/O mapping are subscribed to Make sure that this address range does not match other IT/OT systems in the shared environment.
Use device IP for Unicast	IP address of the device where the application is running
Start port	Port for communication Default: 4840

Table 4. Send/Receive Settings

`Tx Publisher ID`	ID for communication via pub/sub Default: 10
`Tx Writer Group Start ID`	ID for communication via pub/sub Default: 10
`Rx Publisher ID`	ID for communication via pub/sub Default: 20
`Rx Writer Group Start ID`	ID for communication via pub/sub Default: 20

Important

All settings have a tooltip. The tooltip appears when you move the mouse pointer over a setting name.

Tab: Status

This page is for diagnostic purposes. It shows information about the send and read status of the individual tasks.

Tab: Simulation Broker

The simulation broker contains an OPC UA Server with the simulation model of the OPC UA PubSub-configuration. And it can manage the configurations of multiple devices.

Button: Select Broker Device

Opens the Select Device dialog.

Select the desired controller from the list. The broker application can run on any standard CODESYS controller.

Note: The selected runtime system must provide an OPC UA Server.

Note: The device description of the broker device must be installed in the device repository of your CODESYS Development System.

Button: Update Broker

Creates or updates the application of the simulation broker

The created broker application is added to an existing broker setup. If no broker setup is available, then a new one is created, downloaded, and started automatically.
