  Arc Embedded is a cybersecurity sensor built into PLCs to provide real-time visibility and deep threat detection within industrial control systems.
  - Introduction
    An overview of Arc Embedded.
  - Requirements
    The machine and network requirements necessary to use Arc.
  - Preparation
    Information on how to import Arc packages, and install a license.
    - Arc licenses
      Before you can deploy and use Arc, you will need to buy a license. How Arc licenses are installed will depend on the existing installation that you have. Arc and Arc Embedded require separate licenses.
    - Install a license in Guardian or CMC
      Before you can use Arc you must install the applicable license.
    - Import Arc through the update service in Guardian or CMC
      Before you can deploy Arc, you must import it first. There a two methods you can use to do this, one method is through the Nozomi Networks Update Service. The alternative method is through a manual contents upload.

Hardware setup for Mitsubishi Electric MELSEC iQ-R PLC

The recommended physical setup for the Mitsubishi Electric MELSEC iQ-R programmable logic controller (PLC).

The RD55UP12-V module has two network interfaces. Arc uses one of these to connect to the upstream sensor. It is recommended to use the second network interface to monitor and have it connected to a switch SPAN port to get all the data from the central processing unit (CPU) module.

This setup works best in combination with Smart Polling enabled, leveraging the Mitsusbishi Electric MELSOFT strategy. The port used to connect to the upstream is also then used as a Smart Polling interface.
