The interface that ships with the machine
You build the machine, so you are expected to deliver its interface too. Bella SCADA runs on a small computer inside the panel and the customer opens the machine in a browser. No client install, no per-client licence.
The line item that breaks a machine builder's cost
A machine interface is not a one-off job: it is licensed again on every machine you sell. Once an HMI licence that counts tags and clients lands on the per-machine cost, that line item is often what separates your quote from your competitor's.
The second line item is installation. A SCADA that needs a desktop client means installs, updates and IT approvals on the customer's computers. After the machine leaves your factory, your service team carries that load — and the customer's IT department often refuses the install outright.
In Bella SCADA the number of concurrent clients is unlimited and there is no client to install. The operator uses the touch panel on the cabinet door, the maintenance technician uses a phone, the customer's production manager uses a desk browser — all three at the same price.
For reference: Ignition Edge IIoT starts at USD 945 and Tatsoft FrameworX EdgeConnect at USD 750. At its discounted price our Machine / Edge package sits below both — and does not count clients.
Typical architecture
One small computer inside the panel, a browser outside it. No second server in between, and no internet connection required.
1 · Field
The PLC, drives and instruments in the cabinet. Read over Modbus TCP, Modbus RTU, Siemens S7 (ISO-on-TCP) or EtherNet/IP; commands are written over the same connection.
2 · The panel computer
An industrial mini PC or panel PC. A separate process (ScadaRuntime) runs the polling loop; the database and web server run on the same machine. The interface works even if the machine ends up in a factory with no internet.
3 · The interface
The touch screen on the cabinet door opens the HMI full screen (kiosk). The same address opens from a phone and from the customer's office network. Access can be granted per screen — the operator sees the control screen, the customer only the monitoring one.
4 · Output
Active alarm list and alarm history, trend charts, production counters, recipe writes on product changeover. Alarm history and trend reports are sent as Excel or PDF on a schedule.
Protocols used in this vertical
Four drivers cover the machine side. All eleven protocols and their current validation status are listed on the protocols page.
| Protocol | Typical device | Direction | Field validation |
|---|---|---|---|
| Modbus TCP | PLCs with an Ethernet port, drives, power meters | Read + write | Not done |
| Modbus RTU | Serial instruments and motor drives | Read + write | Not done |
| Siemens S7 (ISO-on-TCP) | Siemens S7 family controllers | Read + write | Not done |
| EtherNet/IP | Rockwell / Allen-Bradley family controllers | Read + write | Not done |
The drivers are verified by build and simulation tests; none has yet been tested against real field hardware. We say this at quotation stage: the first task in a pilot is a connection test against your own device. The current matrix lives on the protocols page.
What ships in the box
These are the product's built-in screens; machine-specific visual design is done in the HMI editor.
Live monitoring
A tag list with live values, pushed over SignalR. The page does not reload.
HMI editor and kiosk
Drag-and-drop screen design with a 36-component palette and a symbol library. The screen you design opens full screen at its own address — that is what the cabinet touch panel shows.
Trends
Historical charts for selected tags. Logging interval and deadband are set per tag.
Alarms
Active alarms sorted by priority, acknowledge and shelve, alarm history, and ISA-18.2 indicators (flood, chattering, bad actors).
Recipes
Write a whole parameter set to the machine in one action on product changeover; the applied recipe is recorded.
Reports
There are two report types: alarm history and trend. Excel or PDF, delivered by scheduled e-mail. There is no free-form report designer.
Recommended package
Machine / Edge — one connection, 250 tags, 3 HMI screens, unlimited concurrent clients, alarms and trends. The reporting module is not included in this package. Current price band is on the pricing page.
Move up to Plant if the machine needs more than one connection (a PLC plus a separate power-meter line, for example), if 250 tags are not enough, or if you want to hand the customer shift reports. Plant has no tag, client or screen limit.
The licence is per installation: one machine, one licence. How many people open it does not change the price.
Frequently asked
Do I buy a licence for every machine I sell?
Yes — the licence is per installation, one machine, one licence. There is no per-client charge, so the price does not change with the number of people opening it. Volume terms for serial production are discussed separately.
Can I deliver the interface under my own brand?
Partly. The project name and the logo (separate light and dark variants) are set in system settings, so the customer opens the machine under your logo. Full white-labelling — domain, e-mail templates and every surface carrying the product name — is not part of the standard package and is assessed separately.
Do I have to install anything on the customer's computer?
No. The interface opens in a browser; there is no plugin, no Java, no desktop client. The only install is on the computer inside the panel, and you are the one delivering that.
The machine is going to a factory with no internet. Will it work?
Yes. The server and the browser sit on the same local network; nothing has to reach a cloud. Remote support is a separate decision and depends on the customer's network policy.
My PLC brand is not on the list. What happens?
Most PLCs speak Modbus TCP, which is the first thing to check. If yours does not, a new driver has to be written — that is a project line item, not something out of the box. The driver architecture sits behind a single interface (IDeviceDriver), so adding a protocol does not touch existing code.
Try it against your own machine
Tell us the PLC brand in your panel and the signals you want to read; we will prepare a sample machine screen that speaks that protocol. You do not need to ship us hardware.
