ControlBits
There are 3 Control Bits: PLC_ctrl0, PLC_ctrl2, and PLC_ctrl3. Note that PLC_ctrl1 is not available. The control
bits can be used as software triggers by toggling between two states: True and False. True sets the signal High,
while False sets the signal to Low.
When a bit is toggled on the host software, a Write Register command is sent to the camera. The arrival time
of the packet depends on current network traffic therefore is varied. These are recommended for testing
purposes. For more precise trigger usage please use an external input trigger signal thru the 12-Pin connector.
For a constant periodic trigger signal please use the Pulse Generators (Timers).

PLC LookupTable
The PLC Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17. You
can manipulate your inputs using simple or complex Boolean operations. Each Q output results from the
Boolean operations of 4 input variables and 3 Boolean operators.
