Note that PLC_ctrl1 is not available. The controlbits 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 timeof the packet depends on current network traffic therefore is varied. These are recommended for testingpurposes. 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).Figure 36. ControlBits5.9.3 PLC LookupTableThe PLC Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17. Youcan manipulate your inputs using simple or complex Boolean operations. Each Q output results from theBoolean operations of 4 input variables and 3 Boolean operators.
