1)
The specified delay times refer to the hardware. The actual reaction time
depends on the time slot in which the digital input or output is processed.
2)
In order to use the digital outputs, an external 24 V power supply must be
connected to terminal X124.
3)
Signal cables twisted in pairs and shielded.
