Which sooner or later may cause one of the sending nodes to enter 'Bus-Off' state, i.e. Message identifiers, there will be unresolvable conflicts during the bus arbitration phase, If multiple nodes send CAN frames with the same Which must be avoided under any circumstance. If both (CAN-simulatorĪnd vehicle) were connected simulaneously, this would cause severe collisions on the bus Receive from a vehicle's control unit or similar. In this case, the programming tool sends those messages, which the DUT expects to Is directly conntected to the MKT View (or similar DUT, 'device under test') with a suitableĬAN-bus interface, and no other active CAN nodes

The option Send on real CAN bus should only be used if the PC (with the programming tool) It doesn't affect any external devices connected to the PC. In many cases, this option is already sufficient to test and develop an application Simulation within the programming tool, as a replacement for CAN messages Signal values modified via slider or stimulus (numeric expression) will enter the The option 'Inject values into simulation'īy default, the option Inject values into simulation is set. The display interpreter will periodically evaluate this expression,Īnd use the result as new 'physical' value. To modify multiple values simultaneously, enter a stimulus (numeric expression) in theĬolumn titled 'Expression (Stimulus)'. The above method is only the fastest / easiest way to simulate a single signal. Use the vertical slider (that is now connected to the selected signal) to modify the value.Click into the table on the signal you want to 'simulate' (or send), to select the row.Check option Inject values into simulation, and if you promise to be careful, Send on 'real' CAN bus.Copy ALL signals from UPT display variables

Can bus simulator simulator#
Open the CAN Simulator window: From the tool's main menu, select Tools.The fastest way to simulate all CAN-signals used in your application is to extract theirĭefinition from the application itself (because the 'UPT display variable' definitionsĬontain all the simulator needs to know for assembling such messages): If the PC is connected to a suitable CAN bus interface, it can even send those messagesĮxtracting CAN signal definitions from UPT variables

The CAN message generator can do the opposite: Using the information that you have importedįrom a CAN database, it can assemble CAN messages that it can play "into the display simulator". With tabsheet for the CAN signal definition table and 'value slider'. 'CAN-Simulator' screenshot (part of the UPT programming tool) Your display application already containsĪll that the programming tool needs to know for 'simulating' the signals that in a real-world In that case, the 'CAN simulator' described in this documentĬan be used to replace 'real' CAN signals. So if you can, test everything on the 'real' target hardware.īut sometimes, when developing an application for the programmable display,Ī suitable test environment (like a motor control unit or an entire car or truck) You don't need the CAN message generator / simulator described in this document.Īny simulation will not spot errors like misconfigured CAN bus (baudrate, sampling point, terminators. vehicle with a functional motor control unit, If you have access to the 'real' CAN-Bus, e.g. Hints about the CAN Message Generator usage (for advanced users)ĬAN Message Generator / Bus-Simulator Introduction.Options to synchronize display application and CAN Simulator.Text Console (text screen showing output from 'csim.print').Programmable Buttons (on the 'Automation' tab).Breakpoints and single-stepping through the Conditional Actions.Details about command-driven signal transmission.Access CAN signals / internal variables / timers.Special interpreter commands for the CAN Simulator.
