That's not correct Dave. The digital modules have 4 distinct resource types... PWM channels, Relay Channels, an I2C bus, and Digital I/O channels. Because they are separate resources, you will not get conflicts from using the same channel "number" in a different set of channels. This is best illustrated by looking at the digital sidecar itself and witnessing different pins for each of those channel types.

Code:

ap_elevatorLimitRightTop = new DigitalInput(4, 1);

This has no effect. The default digital module is 4, so explicitly specifying 4 is not any different than not specifying it. In either case, you are allocating the same channel. The reason this works is because the relay channels are separate from the digital I/O channels.
