The A2B Plugin for SigmaStudio+ gives the following default platforms for the user:
In addition to these, the plugin also provides a range of transceivers and generic peripheral devices as follows:
These devices are available as part of the toolbox once inside the platform view/canvas as shown in below, the platform canvas can be opened by double clicking on the platform in the system view or by clicking the “Canvas” option under the platform in the Project window.
The transceivers and peripheral settings window can be opened by double clicking on the transceiver/peripheral in the platform view. Additionally, it can also be opened by clicking on the “Settings” option under the transceiver/peripheral in the project window.

The Network Properties tab, as shown in Figure 61, offers configurable options for the target processor software. With these settings one can select the node discovery and initialization method to be used and the clock source for the A2B network.

The four possible discovery methods are
Simple: All sub nodes are discovered sequentially from sub 0 to the last available sub node in the system. Once all the sub nodes are discovered, they are initialized for synchronous data exchange.
Modified: All sub nodes are discovered and immediately initialized (for synchronous data exchange) sequentially from sub 0 to the last available sub node in the system.
Optimized: Even before a node is initialized the host tries to discover the next node. The time for the next node to be discovered is used to initialize the current node. Synchronous data can start only after all nodes are discovered and initialized (not supported for AD2430 AND AD2438).
Advanced: Even before a node is initialized the host tries to discover the next node. The time for the next node to be discovered is used to initialize the current node. Synchronous data exchange can start as soon as a main and sub node 0 is initialized (not supported for AD243x main).
Discovery Start Delay (ms): Delay (in milliseconds) to wait after a software reset and before discovery start.
The Line Fault settings allow user to enable fault diagnostic feature of the software. With this any line fault encountered in the system is handled and reported to the user.
Override Bus Self Discovery: If checked, Bus self-discovery status is ignored, discovery process starts with the soft-reset of A2B network. If unchecked, software looks for a self-discovered network, configures the network as per the schematic.
Enable Line Fault Diagnostics: Enables line fault diagnostic feature of software. When set, SigmaStudio+ will continuously monitor the network for faults at 1 second interval. Detected faults will be handled and notified.
Rediscovery upon faults: If checked, automatic network rediscovery or partial discovery will be performed upon detecting post-discovery faults.
Stack Debug Settings: This feature allows the user to analyse/ understand the system by using the information logged during stack execution. Information can be either through TRACE or sequence chart or both.
