Unable to start the Fanuc Focas Data Window Library services

The TOP Server Fanuc Focas Ethernet Driver has external dependencies. For this driver to communicate with the hardware, the Fanuc CNC Focas 1/Ethernet Library (part number A02B-0207-K732) or Fanuc Focas 2 Library (part number A02B-0207-K737) must be installed on the system.

Note: The Focas 2 Library combines both Ethernet and HSSB capabilities and can be obtained from the FANUC distributor or by calling 1-888-326-8287. Choose CNC, PARTS, place the order, and request the part number.

Only 32-bit DLL files are compatible with Fanuc Focas Ethernet Driver. Follow these steps to install a library:

  1. Obtain a library from the distributor (typically Fwlib*.zip).
  2. Move or paste the Fwlib*.zip file to the appropriate Windows system folder:
    • On a 64-bit Windows OS, the destination folder is C:\Windows\SysWOW64
    • On a 32-bit Windows OS, the destination folder is C:\Windows\System32
  3. Once the zip file is in the appropriate destination folder, unzip/extract the contents of the Fwlib*.zip.
  4. Verify the 32-bit DLL files are located in the folder; in particular FWLIB32.DLL and FWLIBE1.DLL, which are used by the Fanuc Focas Ethernet Driver.
  5. Restart the computer.

Note: It has been reported by users that the DLL filenames are case-sensitive and must be all caps, as shown in the instructions above.
