GPO - General purpose outputs

At the hardware level, GPO outputs are general-purpose digital outputs that can be configured for various purposes. This block and the associated C/C++ routines provide means to write the value of the corresponding pin at the CPU execution rate. For FPGA users, GPO pins are also available in the sandbox, enabling faster update rates.

The table below outlines the location and logic-voltage levels of the GPO outputs across imperix controllers. Detailed information is available in the product datasheets. For the TPI8032, using the TPI GPO helper block is recommended instead.

Simulink block

Signal specification

The GPO pin is set if the input is >0.

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• GPO pin(s) (vectorizable) is the GPO pin(s) to control. It can be a single value or a vector.
• Reset pin value to 0 in case of fault acts when a fault is detected, for instance when an analog inputs exceeds a configured limit value.
• Show simulation output port defines if the simulation output is displayed or not.

PLECS block

Signal specification

The GPO pin is set if the input is >0.

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• GPO pin(s) (vectorizable) is the GPO pin(s) to control. It can be a single value or a vector.
• Optional reset can be set to Reset pin value to 0 in case of fault to act when a fault is detected, for instance when an analog inputs exceeds a configured limit value.
• Simulation input port defines if the target outport is displayed or not. This parameter is only used in simulation.
