How do I connect the Prisma Coffee Tech Prisma PLC over Ethernet?

Connect the Prisma Coffee Tech Prisma PLC through a router or with a direct Ethernet cable. Router or local network path: connect the roaster and computer to the same network and use the IP address shown on the roaster display. Direct Ethernet path: set the computer Ethernet address manually in the roaster's subnet using the same subnet mask, then enter the roaster IP address in Rostoc.

Connection setup

The Prisma Coffee Tech Prisma PLC connects to Rostoc over Ethernet.Connection: Ethernet.

Setup steps

Option A: Router or local network

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

Option B: Direct Ethernet cable

Connect Ethernet directly from the roaster to your computer.
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.
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.
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.
Leave gateway and DNS blank unless the machine manual gives values.

Finish in Rostoc

Open Rostoc and go to Settings → Machines.
Click + Add Machine and choose Browse Catalogue.
Find "Prisma Coffee Tech Prisma PLC" in the catalog and click Add.
In the machine settings, enter the roaster IP address. Do not enter the computer's static IP address.
Click Connect to begin logging.

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.
