Siemens S7 coffee roaster setup with Rostoc.
Rostoc supports selected coffee roasters that expose live machine data through Siemens S7 over Ethernet. S7 support is exact-machine specific: start from the catalog entry, confirm the S7 setup, and validate readings before relying on the batch record.

Direct Answer
Rostoc can connect to selected Siemens S7 coffee roaster entries in the machine catalog. Support is exact-entry specific, not a blanket claim that every PLC roaster or every brand using Siemens hardware is production-ready.
The practical setup is Ethernet first: put the roaster and computer on the same local network, use the exact catalog entry or manual S7 setup, then compare live BT, ET, and feedback values against the machine display.
- Use the exact Rostoc catalog entry for your brand and model.
- Confirm the machine exposes Siemens S7 over Ethernet before choosing the S7 path.
- Collect the IP address, rack, slot, and any machine-specific setup notes.
- Validate bean temperature, environmental temperature, and feedback streams during a short test.
- Treat S7 writes or controls as separate validation work unless the exact catalog entry says otherwise.
S7 brands to check first
The strongest S7 opportunity in Rostoc today is Giesen because the catalog contains a broad set of Giesen entries with S7 streams. Other S7 catalog families exist, but each should be checked by exact model and support status.
Do not treat a brand name as the protocol. Some popular PLC-connected roasters use Modbus, vendor software, USB, or another controller path in Rostoc rather than S7.
| Brand or family | Current Rostoc guidance | Important caveat |
|---|---|---|
| Giesen WPG, W1, W6, W15, W30, W45, W60, W140, WxA presets | Siemens S7 catalog entries with model-specific streams. | Many external Giesen software setups require an unlock code purchased from Giesen before another application can communicate with the roaster. |
| Buehler Roastmaster and related Simatic entries | S7 catalog entries where listed. | Check the exact Buehler model and controller generation before assuming the map matches. |
| Brambati, Cogen, Kirsch+Mausser, Kuban, Lilla, Petroncini, Probat G/UG | Selected S7 catalog entries exist. | These are not interchangeable; validate the exact catalog entry, stream labels, and values. |
| Loring, CoffeeTool, Diedrich, Coffee-Tech, Toper, Joper, IMF | Popular PLC or automation names in the roasting ecosystem. | They may use Modbus, USB, or another Rostoc path instead of S7. Check the catalog entry rather than assuming Siemens S7. |
Before you connect an S7 roaster
S7 setup fails most often when the network or machine generation is wrong. Before opening Rostoc, collect the details that make the connection deterministic.
If you have an Artisan `.aset` file, it can help identify S7 settings and channel labels. The import is still setup evidence, not proof that the machine is ready for production logging.
- Confirm the brand, exact model, controller generation, and approximate production year.
- Confirm the roaster IP address and make sure the computer can reach it. For direct Ethernet, use a manual computer IP address in the same subnet with the same subnet mask.
- Record the S7 rack and slot if the machine documentation or prior setup provides them.
- Avoid running another application that controls or polls the same roaster during validation.
- Prepare a short roast or warm-up test where BT, ET, and feedback values can be compared safely.
What to validate in Rostoc
S7 support is only useful when the values are readable, plausible, and saved with the right stream identity. A successful socket connection is not enough.
For the first validation pass, focus on read-only logging and saved records. Treat control writes as a later step unless the exact setup has been explicitly tested.
| Validation area | What to check | Why it matters |
|---|---|---|
| Network connection | Rostoc connects to the roaster address without intermittent errors. | S7 uses a local Ethernet path, so IP and subnet mistakes can look like protocol failures. |
| Temperature readings | BT and ET match the roaster display within expected sensor differences. | Wrong DB addresses or value types can create a curve that looks live but is not trustworthy. |
| Feedback streams | Gas, airflow, drum, pressure, or other feedback streams appear in the right chart area. | Feedback values should explain the roast instead of being mistaken for temperature curves. |
| Saved batch replay | A saved test batch reopens with the same labels, units, and chart routing. | The integration needs to preserve data identity after the roast is over. |
Support boundaries
S7 is a setup family, not a universal support promise. Rostoc should only be used with the exact catalog entry or support-guided setup that matches the roaster.
If the machine generation, controller, rack, slot, IP address, or stream labels are uncertain, collect those details before relying on a production roast record.
- Use the exact Rostoc catalog entry for the machine.
- Keep existing setup screenshots or `.aset` files available as evidence.
- Contact support when the machine is missing from the catalog or the readings do not match the display.
FAQ
Does Rostoc support Siemens S7 roasters?
Rostoc supports selected Siemens S7 catalog entries. Check the exact machine page and validate readings before production use.
Is S7 the same as Ethernet?
No. Ethernet is the network connection. Siemens S7 is the PLC protocol Rostoc uses for selected catalog entries over that network.
Which S7 roaster brands should I check first?
Giesen is the largest current S7 family in the Rostoc catalog. Selected Brambati, Buehler, Cogen, Kirsch+Mausser, Kuban, Lilla, Petroncini, and Probat G/UG entries also use S7 where listed.
Can I import an Artisan .aset file for S7 setup?
Yes. An .aset file can provide useful S7 setup evidence, but the imported settings still need to be reviewed against the exact Rostoc catalog entry and tested on hardware.
Can Rostoc control S7 roasters?
Do not assume control support from S7 logging. Validate read-only logging first and rely on the machine's normal controls unless a specific catalog entry and release note say control writes are supported.
