Does Rostoc support the Carmomaq Masteratto?

Yes - Carmomaq Masteratto is supported by Rostoc via Modbus TCP over Ethernet (port 502). This Machine can be connected for real-time roast logging, Curve recording, and roast analysis. For eligible accounts, Rostoc can also control the functions listed below.

Connection setup

The Carmomaq Masteratto connects to Rostoc via Modbus TCP over Ethernet (port 502).Connection: Ethernet.

Setup steps

Option A: Router or local network

1. Connect the roaster with Ethernet.
2. Connect your computer to the same network by Wi-Fi or Ethernet.
3. Find the roaster IP address on the machine display, controller screen, manual, or router device list.

Option B: Direct Ethernet cable

1. Connect Ethernet directly from the roaster to your computer.
2. If the roaster uses automatic network addressing, change it to a manual/static IP first or reserve its address in the router before disconnecting from that router.
3. Set your computer Ethernet IPv4 address manually in the same subnet as the roaster. Use the same subnet mask as the machine and choose a different IP address.
4. For mask 255.255.255.0, usually keep the first three IP blocks the same and change the last one. For mask 255.255.0.0, keep the first two IP blocks and choose another address in that range.
5. Leave gateway and DNS blank unless the machine manual gives values.

Finish in Rostoc

1. Open Rostoc and go to Settings → Machines.
2. Click + Add Machine and choose Browse Catalogue.
3. Find "Carmomaq Masteratto" in the catalog and click Add.
4. In the machine settings, enter the roaster IP address. Do not enter the computer's static IP address.
5. Verify the TCP port (default: 502) and unit ID if the machine page or manual shows one.
6. Click Connect — Rostoc will read all configured data streams automatically.

Troubleshooting

Rostoc cannot connect

Check that the IP address in Rostoc matches the roaster IP address. If you use a router, confirm the computer is on the same local network. If you use a direct cable, confirm the computer and machine use the same subnet mask and different IP addresses in that subnet.

Direct cable setup is unclear

Use a manual IPv4 address on the computer. For a machine at 10.20.0.211 with mask 255.255.255.0, use 10.20.0.42 with that same mask. If the machine uses 255.255.0.0, keep that mask and choose another 10.20.x.x address. Leave gateway/DNS blank unless the machine manual gives values.

IP address changed after restart

A router can assign a new address automatically. Check the machine display or router again, or reserve the machine address in your router.

Connection refused or timed out

Verify the machine is powered on and no firewall is blocking TCP port 502.

Data reads return zeros

Confirm the Modbus unit ID matches the roaster's configuration. Some models require a specific unit ID (slave address).

Intermittent disconnections

Use a wired Ethernet connection instead of Wi-Fi. Check cable integrity and switch/router stability.

Before use

Keep the physical controls and emergency stop accessible, never leave the roaster unattended, and do not run another control application at the same time.
