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 corre-
sponding 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.
Note
②
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 logi-
cal 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.
Note
③
This register is only used for Pins configured as Inputs.
Note
④
This register is only valid for Pins configured as Outputs
INFORMATION
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 produc e
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 out -
put. During this time delay, if you have a device connected to the Pin, it may receive t he
auto-dete
ct circuit’s voltage and leakage current.
