And the output modules seize 2 Instances in Class (0x66).
750-506, 753-506
The 750-506, 753-506 digital output module has 2-bits of diagnostic
information for each output channel. The 2-bit diagnostic information can
then be decoded to determine the exact fault condition of the module (i.e.,
overload, a short circuit, or a broken wire). The 4-bits of diagnostic data are
mapped into the Input Process Image, while the output control bits are in the
Output Process Image.
The output modules seize 4 Instances in Class (0x65).
And the output modules seize 4 Instances in Class (0x66).
