The operating environment is an important consideration when selecting an HMI. These may include cleanroom safety, waterproofing, and more. For example, an HMI in a warehouse application may have excessive noise or vibration, and one may decide to use a heavy-duty HMI with seals to keep out dust, oil, and other particles. If the HMI will be used in the food processing industry, or other applications where equipment may need to be cleaned, a waterproof or splashproof HMI would be an excellent choice. Temperature must also be considered as a factor in the selection process. If it is to be used in a steel mill, near a furnace, the user should select a unit that can withstand extreme temperatures.
Which HMI programming software to choose?
HMIs usually have their own software through which they are programmed. When selecting an HMI to be embedded in your system, make sure that there is an available communication protocol driver in that HMI software. Otherwise, you will not be able to connect the HMI to your CPU and no data display will be transmitted.
