Configuring jobs for FANUC CNC

Prerequisites

A licensed installation of FANUC LADDER-III is required, either on the octoplant server or on an agent.

FANUC CNC memory types

FANUC CNC devices use two types of memory, each with specific characteristics in octoplant:

  • SRAM: Battery-supported RAM that stores parameters, offsets, variables, and other essential data.
  • FROM: Flash ROM that contains the PMC program, SRAM backups, and additional stored data.

Understanding these memory types is key to configuring efficient backups in octoplant.

To ensure comprehensive backups and enable disaster recovery, we recommend creating three separate jobs for three different components, aligned with the file structure in the Project Tree:

  • CNC Data Backup: To safeguard machine-specific settings and offsets
  • PMC Data Backup: To ensure automation logic integrity
  • SRAM Data Backup: Full system recovery in case of critical failure.
    For this job, set Do not compare under Upload and compare as the compare policy.

This structured approach ensures that each type of data is properly backed up and facilitates a more reliable restoration process when needed.

Procedure

  1. Create a job with the Fanuc CNC upload type.
  2. Go to the Fanuc CNC settings section.

  3. Select the Connection type.

    • For an HSSB connection, the computer used for the upload must have a compatible FANUC interface card and the appropriate drivers installed. Additionally, you must specify a node number in the job configuration. The default node number is 0.
    • For a connection via Ethernet, enter an IP address or the device name and the FOCAS port. The default port is 8193.

  4. To restore your FANUC CNC devices with a backup, select the Copy disaster recovery data checkbox.

  5. From the dropdown menu SRAM, select how the SRAM backups should be copied:

    1. Create SRAM backup: Use this option if the device is in emergency stop during job execution. It creates a complete emergency restore backup.
    2. Copy all SRAM backups from F-ROM: Use this option if the device is running (i.e. NOT in emergency stop) during job execution. It is required when a valid SRAM backup cannot be created due to the device type or firmware version.
    3. Try to create SRAM backup, copy SRAM backups from F-ROM if SRAM is blocked: Use this option to apply Option I. to stopped devices and option 2. for running devices. This is the recommended procedure for octoplant.

  6. Determine whether PMC data, CNC data and user data should also be copied when the job is executed.

Unlike FANUC CNC devices, FANUC Robots do not have a dedicated upload type. Instead, backups are performed using generic FTP jobs.

  • If you are backing up a FANUC CNC device, FTP settings are not required.
  • If you are backing up a FANUC Robot, FTP settings must be configured manually in the generic FTP job.
