Most HMIs have a built-in touchscreen to provide feedback and allow input from on-site personnel. If that is all that’s required, a standard HMI may be sufficient. On the other hand, if you have limited panel space, no need for a touch screen, and want the convenience of monitoring and accessing your system without having to walk to where the HMI is physically located, the cMT-SVR units are a great option. Utilize your Apple or Android smart phone or tablet to access cMT-SVR unit remotely.
