Note ②; Note ③; Note ④ - Pulseroller ConveyLinx-IO User Manual

logical state of the Pin's data seen in the Inputs register of the Inputs Assembly will be inverted from the logical
state of the electrical signal on the Pin.
This is provided as a convenience for the remote controller programmer. For example, the remote controller could
have re-useable code or routines that expect a photo sensor to have its electrical signal ON when it is "blocked".
Let's say on a given module, you need to connect a photo sensor whose electrical signal is OFF when "blocked".
Instead of modifying the program logic in each and every place this input is used; you can simply change its logical
polarity with this register
Please note that this register also controls the state of the LED indicators for the given Pin. The LED state will
match the logical state of the pin.
For example, by default when the Left Sensor input is electrically energized, its corresponding LED illuminates
green and bit 4 of the Inputs register in the Inputs Assembly is a 1. If you set bit 4 in the Input Polarity register;
when the Left Sensor input is electrically energized, bit 4 of the Inputs register is 0 and its corresponding LED is off.

OTE
This register is only used for Pins configured as Outputs in the Input/Output register. If a given Pin's corresponding
bit is 0 in this register when the remote controller sets the logical state of the Pin in the Outputs register in the
Output Assembly, the electrical signal on the Pin will match this logical state. If a given Pin's corresponding bit is 1
in this register, the electrical signal on the Pin will be inverted from the logical state.
N ③
OTE
This register is only used for Pins configured as Inputs.
N ④
OTE
This register is only valid for Pins configured as Outputs
Upon power-up, all I/O Pins default to being inputs. Because these input pins are
NPN/PNP auto-sensing, there is a voltage (approx. 12V) on the circuit that will produce
up to a 2 mA leakage current. When using a given Pin as an output, there may be a time
delay between module boot-up and the remote controller configuring the Pin as an
output. During this time delay, if you have a device connected to the Pin, it may receive
the auto-detect circuit's voltage and leakage current.
