A Human Machine Interface (HMI, MMI or OI) allows for operator input to the controller through the use of a computer or touch screen. A visual display of the process can be created to display:

• current status of process equipment
• current process variables
• alarms
• history (both alarm and process variable)

Furthermore, the operator can:

• modify setpoints
• select modes of operation
• select recipes (if applicable to the operation)

 HMI’s can range from single or multi line text display to full color screen PC’s. We have experience in all the major brands (Siemens, AB, Idec, Omron, Redlion, C-more, etc)

Often there is the need to mix HMI and PLC vendors (HMI from vendor A connected to PLC from Vendor B). We are well experienced in this with solutions ranging from custom driver code to OPC implementation

TURN-KEY CONTROLS will create a program to suit the specific application.
