Sequence Tables
The behavior in automatic mode is described in sequence tables found in the following folders for your application.
- PTC2EM and PTC3EM:
- PTV2EM:
- PTV3EM:
Limitations of the Test Run
These parameters are defined in following folders for your application. The adjustable variables are located in the group Set_Point_Limitation.

Structure of the Sequence Tables
This section describes the characteristics of the sequence tables for the powertrain application. For a more general description of the parameterization of sequence tables, refer to the PAtools User Manual.
The columns of the sequence tables can be divided into the following categories:
- General columns
- Columns regarding the step-enabling condition and the exit condition
- Columns to select an action
- Columns for the parameterization of the control mode and the concerning set values
You can parameterize both columns with a formula that results in a logical true or false (e. g., temperature > 80 °C). The two columns differ in the following respects:
- Step enabling condition:
- The result of this formula is checked after the end of the measurement phase.
- If the result is true, the step is aborted, and the next step is started.
- Exit condition:
- The result of this formula is checked immediately after starting the step.
- If the result is true, there are two options:
- The step is aborted, and the next step is started (same behavior as the progression condition).
- The complete test is aborted.
In the first column, you may select different actions. The displayed actions can vary and are not the same for each application.
| Action | Explanation | |
|---|---|---|
| Measurement |
Different measurement setups can be started, stopped, or set into pause. By selecting Version change, a new measurement file will be created. |
|
| Driving cycle | You can execute a drive cycle parameterized in a step table, or read from a data file. Depending on the selected item, you have to parameterize the name of the step table, or the name of the data file. | |
| Test run | The following actions can be selected. | |
| Message | Sending a message to the test logbook. | |
| Break | Make a break for a given time. | |
| Setpoint reference |
Select if the setpoint values are given in absolute units (Nm, rpm), or as a percentage value (0-1). |
|
| Wait for OK | Open a message box and wait until user interaction. | |
| Set value | Set a norm name to a given value. | |
| Message Exit condition fulfilled |
In an exit condition, if an individual message text should be sent to the test logbook, this message can be written here. |
|
| Message Progression condition fulfilled |
In a progression condition, if an individual message text should be sent to the test logbook, this message can be written here. |
|
| Read table parameters | Reads a value from a table and writes it to a norm name. | |
| End, leave automatic mode | Stops the sequence table and ends automatic mode. | |
| End, stay in automatic mode |
Stops the sequence table, but the automatic mode remains active. |
|
| End, switch off testbench |
Stops the sequence table, ends automatic mode and switches off the system. |
|
| Clutch | In the case of manual transmission: Engages and disengages the clutch. This action is only used when a controllable clutch is present. | |
| Terminal | The following actions can be selected: | |
| Terminal 30 off | ||
| Terminal 30 on | ||
| Terminal 15 off | ||
| Terminal 15 on | ||
| STMC begin block | Defines the beginning of a new block. Blocks are used for grouping commands. | |
| STMC run block | Defines the end of a block. The return values of the modules are evaluated but the step control does not wait for the return value of the STMC module. | |
| STMC run block and wait | Defines the end of a block. The return values of the modules are evaluated and the step control waits for the return value of the STMC module. | |
| Contactors (STMC) | The following actions can be selected: | |
| Init | ||
| DUT1 DC short circuit | ||
| DUT2 DC short circuit | ||
| External setpoints (STMC) | Starts the activation of external setpoints. | |
| Container (STMC) | Opening or closing of a container. | |
| Battery Simulation (STMC) | The following actions can be selected: | |
| Start U=f(SOC) Simulation | ||
| Start U=f(SOC) Simulation | ||
| Set R1 [mOhm]—enter setpoint for the resistance in the next column | ||
| Set SOC [%]—enter setpoint for the state of charge in the next column | ||
| Set SOH [%]—enter setpoint for the state of health in the next column | ||
| VES3 (STMC) | The following actions can be selected: | |
| Switch VES3 on | ||
| Deactivate pulseblock | ||
| Set Voltage—enter setpoint for the voltage in the next column | ||
| Set current limit—enter setpoint for the current limit in the next column | ||
| Activate pulseblock | ||
| Switch VES off | ||
| Gear Shift | Select between: | |
| Gear_A | ||
| Gear_B | ||
| Gearbox | ||
| Enter target gear in the next column. | ||
| Brake | Starts and stops braking in control mode T/angle. | |
| Timer | Select a predefined Timer (Timer_1 or Timer_2). | |
| The following actions can be selected: | ||
| Start | ||
| Pause | ||
| Wait and Reset | ||
| Enter Waiting time in the next column. | ||
