This block is part of the I/O Blocks categories.
Function
Provides write access to any physical digital output. (All read at the same time) It minimizes the number of
blocks required to configure all of the digital I/O required in the system. It provides a digital status from the
algorithms and functions to physical logic output hardware. Each block output requires a module and
channel number during configuration. The output status may be inverted.
