Connect FANUC Power Mate i and Power Motion i
Power Mate i and Power Motion i-A are FANUC motion controls read with the same FOCAS drivers as the CNC series. FOCAS2 covers Power Motion i-A (PMi-A); commercial FOCAS drivers list Power Mate i. Softing edgeConnector and SDEX list Power Motion i-A among supported controls.

Software versions
- FOCAS2: FS30i/31i/32i/35i, FS0i-D/F and PMi-A.
Data you can read
- Program: running main program number and name, program comment, current block and sequence number
- Status: mode, run state, emergency stop, alarm state, operator messages
- Feed and spindle: feedrate and spindle overrides, actual feed and spindle speed, spindle load
- PMC (ladder) areas such as R, D, G, F, X, Y, availability depending on the model
Setting it up
- Pick the Ethernet portUse the embedded Ethernet port (connector CD38A on the CNC unit) or an Ethernet / Fast Ethernet board if fitted. On the setting screen the active device must be the embedded port, not the memory card slot.
- Set the address on the CNCSYSTEM → [ETHER BOARD] or [EMBED PORT] (shown as ETHPRM / EMBDD on some screens) → [COMMON]: IP address, subnet mask, router. Use a fixed address agreed with plant IT.
- Set the FOCAS portSame screen → [FOCAS2]: TCP port 8193 is the usual default (allowed range 5001 to 65535). Leave the UDP port at 0 and the time interval at 0 for FOCAS2 use.
- Install the FOCAS library on the collectorFOCAS client software needs FANUC's FOCAS library: A02B-0207-K732 (FOCAS1, Ethernet) or A02B-0207-K737 (FOCAS2, Ethernet and HSSB), bought from a FANUC distributor. Commercial drivers will not run without it.
- Test from the plant networkOpen TCP 8193 from the collector to the CNC, connect with your driver and read a harmless value first: program number, mode, part count. Then add the rest of the tags.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|
| Driver connects to nothing, CNC answers ping | FOCAS function not enabled, or the wrong port number in the driver | Check the [FOCAS2] TCP port on the CNC screen and confirm with the builder that the FOCAS Ethernet function is enabled. |
| Connection refused when a second PC connects | Client limit of the port in use | Embedded Ethernet is meant for few clients (one PC recommended); an Ethernet board accepts more and a Fast Ethernet board the most. Use one collector and share its data instead of letting every tool open its own connection. |
| Driver installed, project will not run | FOCAS library DLLs missing or wrong bitness | Install the FANUC library (K732 or K737). Commercial OPC drivers use the 32-bit DLLs (FWLIB32.DLL, FWLIBE1.DLL); file names must be in capitals. |
Traps to avoid
- Axis and program functions vary with what the builder configured; test each tag before relying on it.
