Human machine interface software has been released by CD Automation to enhance its temperature controller. With the REVO HMI, the REVO TC can monitor up to 30 zones from a 4.3, 7, or 10" colour display. The zone description area can also be tapped into, giving access to an advanced parameter and setup page for each zone.

The REVO HMI can display four or eight loop pages, which feature a zone description that can be edited by the user, on-off pushbutton, set-point display and setting, temperature measured display, power output value, generic alarm status, deviation graph and trend display push button for each zone. 

Each loop can have a dedicated trend page that provides a graphical time display of set-point value and temperature control response. A 15 minute log can be shown at any one time on a maximum of 24 operating pages, including four graphical displays.

Control parameters include proportional band, integral time, derivative time, cooling gain, overlap for proportional band, pre-tune activation and self-tune activation.
