2 Channel Digital Input Modules with Diagnostics and Input Process
Data
750-507 (-508), -522, 753-507
The 750-507 (-508), -522 and 753-507 digital output modules have a diagnos-
tic bit for each output channel. When an output fault condition occurs (i.e.,
overload, short circuit, or broken wire), a diagnostic bit is set. The diagnostic
data is mapped into the Input Process Image, while the output control bits are
in the Output Process Image.
750-506, 753-506
The 750-506, 753-506 digital output module has 2-bits of diagnostic informa-
tion for each output channel. The 2-bit diagnostic information can then be de-
coded 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 Proc-
ess Image.
