The BLACKBOX from AUTEM provides an ultra-compact data acquisition computer for the long-term recording of PLC signals and external electrical values (PLC process data archiving) and also remote maintenance using the PLC-ANALYZER pro 5. Due to its small dimensions, the system can be integrated in a switching cabinet without any problem. The BLACKBOX can continuously record and archive processing data over a longer period of time; typically in excess of 3 years.
