Hardware classes on a machine
Exact models stay on sungeneiot.com. This page only names the classes used on plant-floor jobs.
Classes
Remote I/O and RTU
When the machine has contacts and analogs but no spare PLC card.
Protocol gateway
When a PLC already holds the data and another system must read it.
Current and energy inputs
CTs, 4–20mA transducers, pulse counters.
Vibration and temperature nodes
Wired or wireless, chosen after mount and power are known.
