10 INTER-PSL INPUTS AND OUTPUTSTo make the design of PSL schemes easier, P40 Agile provides a range of DDB signals for conncting PSL Inputs toPSL Outputs. these are called Inter-PSL inputs and outputs. This facility allows you to map many PSL input signalsto a single Inter-PSL output signal, many PSL output signals to a single Inter-PSL input signal, and to join the Inter-PSL input signal to an Inter-PSL output signal. The Inter-PSL input signals can also be used to directly trigger theDisturbance Recorder.Chapter 15 - Digital I/O and PSL Configuration P24xM302 P24xM-TM-EN-2.1
