HMI's

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 multiple line text display to full color PC screens. We have experience with 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). The team at TURN-KEY CONTROLS is well-experienced. Solutions range from custom driver code to OPC implementation. A program will be created to suit your specific application.
