HMI SecurityIn today's IIoT world, security is a top priority. Demands for instantaneous data from all levels of production have put increased pressure on OEMs and systems integrators to provide remote access to the manufacturing plant. Just as important though, is ensuring that the safety of employees and protection of company equipment and intellectual property is not compromised. Maple Systems HMIs provide several layers of security features that keep your control system safe, yet still accessible to personnel located outside the plant.
Protect your HMI from Unauthorized AccessFirst and foremost, Maple Systems HMIs offer the ability to protect your HMI data with extensive password control. Use a password to restrict access to the HMI's local setup menus. Uploading or downloading a new project to the HMI can be password-protected as well as retrieving stored data in the HMI. Access from connected devices such as PCs, other HMIs or smart devices are also password-protected.
Protected and Secure Remote AccessUsing EasyAccess 2.0, remote PCs with an Internet connection can communicate to Maple Advanced and cMT HMIs for screen monitoring or to change settings on the HMI or connected PLC, lowering the cost of screen updates and minimizing down time. It is of paramount importance that this connection be secure. This is why Maple Systems employs a VPN (Virtual Private Network) connection and SSL encryption for remote communication. Wi-Fi access to cMT series using cMT Viewer is also password-protected. With the press of a button on the HMI, remote access can be temporarily disabled.
Secure Password Authentication (SPA) is also an important factor when sending predefined email messages from HMIs that contain sensitive data or information about an alarm event. The email function employs the SMTP protocol with the option for data encryption (SSL and TLS supported).
Many of our HMIs possess two Ethernet ports which provide a physical separation between your local network and the web. Our HMI series uses a proprietary operating system that further reduces susceptibility to viruses or malware.
Administrator-Based User AccessHMI screens, data objects (such as Video Player or Data Block Displays), or input objects (i.e. momentary buttons, toggle switches, or data entry) can be activated by users based upon an administrator-based user access feature on Maple HMIs. Objects with restricted access are invisible or display an "access-denied" warning message. Up to 12 users (128 users with USB security key) can be configured each with a unique username and alphanumeric password. The administrator can add, delete, or modify the list of users during HMI runtime. Easily select from a user list, then enter the assigned password to change the access level.
Safety Comes FirstSecurity is a necessity, but just as important is ensuring that the operation of an HMI is conducted in a safe environment. All HMIs can be temporarily taken offline with the press of a button. Use the interlock feature, which monitors the status of a safety bit when activating potentially dangerous equipment. Other safety features include the option of a minimum press time before a button is engaged or the display of a confirmation window. The Operation Log feature records each action of the HMI operator to help determine incorrect action sequences and to reinforce proper HMI operation.
Enhanced Security FeaturesManage access to your control system and keep your facility safe. Our configuration software offers enhanced operational security features to prevent unauthorized personnel from accessing windows in the HMI or from operating critical functions including:
Alphanumeric User Names and Passwords
Add/Delete Users at Any Time
USB Security Key LoginLogin directly with a USB Security Key. Login information can be stored on a USB flash drive and allow a user to be logged in using a Function Key.
Secure Remote Access
Sample project: Security – Security features including select user, login, security classes, update password, object security and window security.
Sample project: Security – Enhanced Basic – Demonstrates how to use the preconfigured security windows in EZwarePlus to log in and out with a pop up window and to modify account settings using Enhanced Security.
Sample project: Security Password Pop-Up – Demonstrates General mode security using a pop up window to login for one user.
Sample project: Security – Window Change – Allows users to log in using a common screen and once logged in, the HMI will automatically take the user to a different screen based on the access level of the user.
