The customer asks for production data after the machine is built. The data path belongs on the drawing: remote I/O beside the controls, a serial port on the network, a switch made for the panel, and a meter at the entry.

Put the data layer beside the controls, not inside them. Remote I/O reads states, counts and temperatures at the sensor and serves them over Modbus TCP. The qualified controller is never opened. A serial instrument joins the network and keeps its COM port. A meter at the entry measures what the machine draws, and a feeder monitor shows which branch.
Data added inside the controller means opening a control project that was already qualified. Remote I/O beside the controls leaves it untouched, so what was validated stays validated.
An instrument with only an RS-232 or RS-485 port is where these projects usually die. On Ethernet to serial, the plant PC still sees the same COM port.
An office switch is built for a desk. The switch in the panel has to take the temperature, the DIN rail and the vibration.
The service is sized for the whole site, and the total is all anyone has. Until each feeder gets its own kWh, no one knows which branch draws it.
One part per decision, each with one fact from its own sheet. The brand name opens that product line.

A relay that reports its own state turns a service call into a diagnosis.
The printed fact. SOD and SILD versions report heater diagnostics. Single to four phase SSRs in okpac and celpac packages sit beside them.

The data the machine collects is read at the machine, on a screen built for the floor.
The printed fact. iView operator interfaces on the same ecosystem as the IMO logic. InduSmart panel PCs from 10.1 to 21.5 inches, IP65 front, fanless, Windows or Linux.

States, counts and temperatures come off the machine with the controller untouched.
The printed fact. Analog, digital, RTD and thermocouple inputs presented as Modbus TCP devices your own software polls. A pushbutton or a foot switch is a digital input too.

An instrument with only a serial port joins the network, and nothing in the software changes.
The printed fact. PoE, DB9 and industrial versions. The plant PC still sees the same COM port.

The switch in the panel takes the heat and the vibration. The one inside your product is a board.
The printed fact. Fast Ethernet, gigabit and PoE, 4, 5 and 8 port. Board-level switching 55 by 55 by 10 millimeters, rated -40 to +85 C.

The counting, buffering and protocol work go beside the PLC, not into it.
The printed fact. A Raspberry Pi based industrial edge computer with I/O, serial and Ethernet on one DIN-rail unit.

The kWh per cycle a customer asks for is measured, not modeled.
The printed fact. A Class 0.2S revenue meter and a Class A Edition 3.1 power quality analyzer in one device, with every event stamped to 1 microsecond.

Each branch gets its own kWh, added after commissioning if it has to be.
The printed fact. Up to 54 single-phase or 18 three-phase circuits from one DIN-rail unit. HACS sensors feed the meter directly, one CT in the chain instead of two.

The Ethernet crosses the machine split in the same hood as the power and the signals.
The printed fact. Inserts for power, signal and Ethernet in one frame. Mate the inserts, snap the hood and energize.
Yes, if the monitoring sits beside the controller rather than inside it. Brainboxes remote I/O reads states, counts and temperatures at the sensor and presents them as Modbus TCP devices. The qualified controller is never touched, so what was validated stays validated.
Modbus TCP is the plain Ethernet protocol most plant software, building systems and SCADA already poll. Brainboxes remote I/O and SATEC meters both present as Modbus TCP devices. The machine ships with a data interface the customer's IT already understands.
Yes. A Brainboxes Ethernet to serial converter puts the RS-232 or RS-485 port on the network, and the plant PC still sees the same COM port. Nothing in the software changes.
As accurate as the CT chain lets it be. A Class 0.2S meter behind a 1 percent CT is a 1 percent system, and the error grows with every point you sum. SATEC HACS sensors feed the meter directly, one CT in the chain instead of two.
The machine, the data your customer asks for, and the software that will poll it. From that we help you specify the parts on the path from the sensor to that screen. The parts are quoted through the distributor you already buy from.
After 30-plus years in the industrial hardware space we know these products, on our line card and off it. Bring us your most stringent or most mundane requirement. If one of our product lines fits, we will show you where. If it does not, we know someone who will. We would be happy to help.
Every product line on two pages, in the order a machine gets designed.
