Using DeviceLogix G-9Example 2 – Writing data to the networkThe DeviceLogix program controls an Analog Output value which iswritten to DLX Real OutSP1.Drive Datalink Value753 Port 0 P905 [Data Out A1] Port 14: DLX Real OutSP1755 Port 13 P17 [DL To Net 01]DLX Real OutSP1 can now be used as a Hardware Analog Output and useddirectly with a Function Block (a DeviceLogix Datalink is not required).Program ExamplesExample 1: Selector Switch OperationThis example demonstrates how a selector switch operation similar to thefeature in the PowerFlex 700S can be achieved through the embeddedDeviceLogix in the PowerFlex 750-Series drive. A Selector switch issimulated in the drive using a combination of inputs to produce multipleoutputs. Digital inputs in the drive are used to output configurable multiplepreset speeds (75 Hz, 85Hz, 95Hz, and 105Hz) to P571 [Preset Speed 1]. Itis assumed that the 750-Series drive has an I/O module installed in Port 4.The truth table below represents the inputs and outputs for a 4 positionselector switch.InputsOutputsInput 1 Input 2 Binary Output Selector SwitchOutput0 0 0 Output A0 1 1 Output B1 0 2 Output C1 1 3 Output DThe Logic Map below offers a high level explanation of how the aboveoutputs are achieved.PowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
