Modicon M580 and Modicon M580 Safety

This system word can be used to:

• Read the FPGA version for Modicon M580 and Modicon M580 Safety.

• Set the auto-reboot feature for Modicon M580.

The bits of this system word are as follows:

• bit 0:

  • 1 enables Modicon M580 auto-reboot if the controller becomes non-operational

  • 0 disables Modicon M580 auto-reboot.

  NOTE: Bit 0 (auto-reboot) is automatically reset to 0 after an INIT.

• bits 1...3: unused

• bits 4...15: version of the FPGA

  NOTE: Auto-reboot feature is available for FPGA versions 1.6 and any subsequent supporting version(s).

For example:

• FPGA 1.5: %SW130 = 0x1050

• FPGA 1.6 + auto-reboot inactive: %SW130 = 0x1060

• FPGA 1.6 + auto-reboot active: %SW130 = 0x1061

During an auto-reboot, the outputs enter fallback state. After auto-reboot the controller enters STOP state and:

• Outputs in the local rack are de-energized.

• Outputs in remote racks enter fallback state.
