This document describes information on the following topics for use of Harmony P6 Series (hereinafter referred to as this product).

• Security measures
• How to use System Monitor Sample Dashboard (hereinafter referred to as System Monitor)
• Dedicated Node for this product.
• System Monitor API
• System Monitor FAQ
• 16DI/8DO API

• When using this product in a network environment, keep a network to be constructed secured. (For example, installing network security devices such as Firewall device).
  For details, ask the administrator of networks for equipment

• Windows Automatic Update is set to be disabled by the factory default in the policy setting. Change the setting if automatic update is needed.
  How to enable Windows Automatic Update
• When using Write Filter, update with the Write Filter disabled.
• After installation of the product, periodically check the “Patch qualification” page to apply the listed Qualified Security Updates (QFEs) to keep the OS up-to-date.
• If the use environment does not allow you to apply security update regularly, it is recommended to take a security measure with a allowlist method by purchasing our optional Trellix license.

• At the time of usual use, use the user created as Standard User for the account type. Only when the system settings need to change, use the user whose account type is Administrator.
  Create a Standard User account

• The environment setting file of Node-RED is retained in every user account. When changing the settings, change the settings with every user account.

• The default username is [admin] and the password is [Pw#12345].
• Change the username and password of Node-RED after the first login. Please set a strong password. For how to change, refer to following URL. https://nodered.org/docs/user-guide/runtime/securing-node-red
• The expiration date of log-in information -token- is 7 days by default. If you log into the flow editor and close it without logout, the log-in state is retained for 7 days. When closing the editor screen, make sure that you log out.
• The way to change the expiration date of the log-in information -token- is also described in the URL above.

• Node-RED uses TCP Port 1880 by default. When the port number is used in another application, use another port number.
• If the port number of Node-RED needs to be changed, refer to the following URL.
  https://nodered.org/docs/user-guide/runtime/configuration

• As described in the following URL, if you configure Windows Service settings to automatically start Node.js and Node-RED at system startup, you can run the flow without log-in. However, if the service is started with the system account, all operations, such as OS setting changes, will become possible due to the flow. Configure the settings taking into account that security risk of the system may increase.
  https://nodered.org/docs/faq/starting-node-red-on-boot
• On the pre-installed OS of this product, to increase the security, Node.js and Node-RED are configured to be run with a user account that you log into.

• The Node-RED configuration file is saved in the %USERPROFILE% folder. You can freely edit or delete the file even with a Standard User account. Changing the access authority of the Node-RED configuration file in the following steps can increase the safety level of the system.
