Your PLC is the best source for process information. Unfortunately, three major technological hurdles exist in most common
manufacturing systems: low availability of...
- PLC scan time for additional logic
- PLC memory for additional logic and data storage
- PLC communication bandwidth for data transmission
SCADA has major flaws — it eats up substantial amounts of PLC memory and can interfere with the actual manufacturing processes.
And traditional MES aren't an effective solution — they provide a lot of data — but you cannot assemble this
data into actionable information quickly or easily.
