White Paper: A New Generation in IP-based Data Acquisition and Control, from MOXA
For several decades, PC-based solutions have been widely used for 
data acquisition and control in industrial automation. Early 
implementations relied on expansion cards inside a PC to attach I/O 
devices such as sensors, switches, alarms, etc. However, this solution 
was not effective over long distances due to the inherent limitations of 
I/O signal transfer. Serial remote I/O modules were later developed, 
allowing wiring to be extended over greater distances. However, serial 
remote I/O was unable to handle demands for long-range, multi-point 
monitoring and control.Download the white paper now
