Operator GPO

Operator Library: Hardware Platform

The GPO operator provides an interface to the digital outputs. Via the Pin_ID / PinID parameter (the name of the parameter depends on the hardware platform), you select the digital output (which is wired to a physical pin on a GPIO unit) you want to use for sending a signal.

For all platforms except the imaFlex platforms: If you use a frame grabber with two GPIO units, use the ConnectorType parameter to select the GPIO unit you want to address (GPIO or Front GPIO). On the imaFlex 2 Dual 100, imaFlex CXP-12 Quad and imaFlex CXP-12 Penta platforms, the ConnectorType parameter is not available.

Each digital output can only be used once. Thus, the selected digital output is to be used by exclusively one instance of the GPO operator.

[Note] Front GPO Port Groups on the imaFlex 2 Dual 100 Platform

The front GPO ports on the imaFlex 2 Dual 100 platform are divided into two independent groups:

  • Each group can use a different power supply voltage.

  • GPO and GPI groups do not share the same supply voltage.

  • Each group has its own dedicated power supply pins.

For the mapping of digital inputs and pin connectors, see the GPIO Connectors topic of your frame grabber User Manual. For the imaFlex 2 Dual 100 plaform, see GPIO Connectors (CoF Frame Grabbers).

Resources

The FPGA device resources of this operator are equal to value of the PinID parameter. You can see the FPGA device resources, if you open the FPGA Device Resources dialog from the Analysis menu. The device resources are read-only:

Figure 433. FPGA Device Resources


For the imaFlex 2 Dual 100 platform, the resource is of type GPO with index 0 to 7 for Front GPIO connector and 8 to 15 – for the Extension GPIO connector.

For each digital output, one device resource of type TriggerOut is used. See Device Resources for a full list of device resources.

imaFlex CXP-12 Quad:{FrontGpo0, FrontGpo1, ExtensionGpo0, ExtensionGpo1, ExtensionGpo2, ExtensionGpo3, ExtensionGpo4, ExtensionGpo5, ExtensionGpo6, ExtensionGpo7}

Via the PinID parameter, you define the digital output (which is wired to a physical pin on a GPIO socket) you want to use for sending a signal. The same digital output can be used only once, i.e., by one instance of the GPO operator.

FrontGpoN represents the GPO for the Front GPIO connector.

ExtensionGpoN represents the GPO for Extension GPIO side connector.

For the mapping of digital inputs and pin connectors, see the GPIO Connectors topic of your frame grabber User Manual. For the imaFlex 2 Dual 100 plaform, see GPIO Connectors (CoF Frame Grabbers).

Pin_ID (mE5 platforms, pixelPlant and LightBridge VCL)
Type static write parameter
Default 0
Range [0;7], [0;3] or [0;1]

Via parameter Pin_ID, you define the digital ouput (which is wired to a physical pin on the GPIO or FrontGPIO socket) you want to use for sending a signal. The same digital output can be used only once, i.e., by one instance of the GPO operator.

[0;7] When you address the GPIO on marathon, or if you use a device with only one GPIO unit (ironman, PixelPlant), the value range is 0 - 7.

[0;3] When you address the GPIO on LightBridge, the value range is 0-3.

[0;1] When you address the Front GPIO on marathon or LightBridge, the value range is 0-1.

Range {GPIO, FrontGPIO}

Via parameter ConnectorType, you define which GPIO socket (GPIO or Front GPIO) you want to address with the value you enter for parameter Pin_ID.

This parameter is only available for platforms that have a Front GPIO:

  • mE5 marathon VCLx

  • mE5 marathon VCL

  • mE5 marathon VCX-QP
