BUSMUST advanced features

Feature scope

BUSMUST Advanced Features extend BUSMASTER with device-oriented capabilities, including:

• Routing: forwards messages on the device or in the application.
• Offline Logging: records bus traffic without keeping a PC connected.
• Offline Replay: replays a stored message sequence without keeping a PC connected.
• Device-timed transmission: runs supported periodic transmission jobs with device timing resources.

Routing

Routing forwards messages that match a channel or identifier rule to another channel. It is useful for gateway testing, forwarding verification, and simple bridge applications. Before enabling a rule, verify the source channel, destination channel, filter conditions, and any identifier or payload conversion.

Key fields include:

• Type: direct forwarding, message-type mapping, identifier mapping, or identifier-and-type mapping.
• Source: source channel or matching condition.
• Target: destination channel or mapped value.
• Message Type: standard, extended, CAN FD, BRS, RTR, and other supported frame attributes.
• Id Mask/Source: source identifier or mask used to select messages.
• Id Value/Target: identifier value to match or the mapped destination identifier.
• Add/Up/Down/Delete: creates, orders, or removes rules.
• Save/Load/Clear device offline storage: writes rules to the device, reads them back, or clears stored offline configuration.

Offline Logging

Offline Logging records bus traffic on a supported device and is intended for installations where a PC cannot remain connected. Confirm the channels, trigger conditions, available storage, and export workflow before deployment.

Key fields include:

• Device: the BUSMUST device that performs the recording.
• Channels: channels included in the recording task.
• Mode: enables or disables the task.
• Direction: records Rx, Tx, or both, depending on device capability.
• Path and file format: device-side path, file number, and format such as ASC.
• Path Mode: controls path or file-number generation.
• Trigger Start/Stop: starts or stops recording when ID, ID Mask, and Flags conditions match.
• Segmentation: splits files by message count, elapsed time, or byte size.
• Overwrite Old File On Full: overwrites the oldest file when storage is full.
• Create New File On Start: creates a new file whenever recording starts.

Offline Replay

Offline Replay lets a supported device repeatedly transmit a known message sequence. Confirm the replay file, output channels, timing, loop behavior, and stop conditions before enabling the task.

Key fields include:

• Device: the BUSMUST device that performs replay.
• Channels: replay output channels.
• Mode: enables or disables replay.
• Direction: selects the recorded direction when direction information is present.
• Path and file format: device-side replay path, file number, and format such as BBD.
• Download replay file to device: transfers a replay file to the device.
• Trigger Start/Stop: starts or stops replay when ID, ID Mask, and Flags conditions match.
• Msg Delay: delay between messages.
• Session Delay: delay before the replay session starts.
• Cycle Delay: delay between replay cycles.
• Enable Cyclic Replay: repeats the replay sequence.
• Force Zero Timestamp On First Message: uses the first message timestamp as time zero.

How offline functions differ from standard logging and replay

• Standard Logging and Replay require BUSMASTER to remain running on the PC.
• Offline Logging and Replay execute on a supported device and can continue without the PC.
• Standard functions are convenient for interactive tuning. Offline functions are preferable for unattended or long-duration operation.
