No-nc

Could it be that the poster was asking about output modules in which the physical configuration (NPN - PNP) and the normal status (NO - NC) was programmable for each output? If so I have never heard of that. The closest would be relay outputs where each relay had the swinger, NO and NC contacts available on the terminals. I have seen those. Though I may just be reading too much into the question.
 
Siemens ET200S 4DO​
VN330SP​
QUAD HIGH SIDE SMART POWER SOLID STATE RELAY
The VN330SP(8932) is a monolithic device made using STMicroelectronics VIPower Technology, intended for driving four indipendent resistive or inductive loads with one side connected to ground. Active current limitation avoids dropping the system power supply in case of shorted load.​
Built-in thermal shut-down protects the chip from overtemperature and short circuit. The open drain diagnostic output indicates over-temperatureconditions.​
