8DO Function Block
Description
The 8DO label stands for Eight Point Digital Outputs.
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.
Input
IN D1
= Input Status Signal
IN D2 = Input Status Signal
IN D3 = Input Status Signal
IN D4 = Input Status Signal
IN D5 = Input Status Signal
IN D6 = Input Status Signal
IN D7 = Input Status Signal
IN D8 = Input Status Signal
Output
FAIL
= Failed Output Indication - Module Error
