The interface consists of a simple Menu Screen  which gives the operator the ability to access the following functions: Login, Process Monitoring, Setup Page, Operations Page, Programmable Parameters Page, Comm Parameter Setup and other powerful InstantHMI Functions. In addition, convenient Troubleshoot function is included.

Help provides help for all on-screen InstantHMI functionality, detailing each action item.

Built-in Login Password Security feature allows only authorized access to InstantHMI functions. Our new IHMISecure™ Interface prevents unintended exit from InstantHMI or unauthorized access to any other handheld applications. This ensures uninterrupted Data Logging or other ongoing InstantHMI activity.

Comm Setup allows selection of IRDA or Serial Link and setting of communications parameters such as Baud Rate, Parity, Data Bits, Stop Bits, Unit ID etc.

Setup Page parameters help identify input/output devices connected to the SD-controller and how the controller should function. The OEM or system designer should normally setup most of these parameters.

Tap on the Configuration button to access the InstantHMI configuration functions: Save, Restore, Review and Modify. You may save several configurations in the handheld under names of your choice and Review any previously saved configuration and Restore it back to the same or a different SD controller. These configuration parameters can be easily edited (if necessary) on the review screen in InstantHMI and restored to the same or different controller which makes controller configuration quick and easy.

   
   


The Home Page allows access to monitor and or modify the parameters listed under the 'Home Page' section of the Watlow SD User's Manual. In addition, you may tap on the Process Monitor button to access the Process Value, Set Point and the Alarm Status for the various outputs. The Set Point can be adjusted by units using the left up/down Spinner controls and by decimal increments using the right up/down Spinner controls. The Bar Graph button shows a bar graph of the Set Point and Process values. Other items of interest may be included in the bar graph by tapping on the Properties button.

The Operations button provides an easy way for the operator to review/change operational parameters such as autotune, PID parameters, alarm set points etc. InstantHMI mimics the functionality of the Watlow SD controller and hides the irrelevant tags from the Operations Parameters Page; this helps in keeping the Operator focussed on the relevant parameters.

The Program Page allows you to configure your own customized Operations Page easily. For each of the Program Page parameters P1, P2, ..., P20 tap on the I (Input) button and select 'None' or one of the tags from the list of displayed Tag variables. This will configure a customized Operations Page on the Watlow controller containing up to 20 variables which can be viewed on the Operations Page on the Palm.


The Factory Page allows monitoring of Output process values (which can be recorded on the handheld and studied in a trend graph). In addition, important controller information such as serial number, software version etc. can be viewed here. Tap on the Diagnostics button to view the diagnostics screen which shows the Watlow SD Hardware Serial Number and the Firmware version. In addition buttons are provided to Restore Default Parameters and Factory Calibration as well as Save / Restore User Settings.

The Troubleshoot button leads to an interactive selection of System Components (Display, Communication, Outputs, Alarms, Control, and Errors) and the Observed Symptoms (Indication). This displays a small subset of Probable Causes for you to select so that you may focus on the corresponding Corrective Actions displayed on the PDA. The InstantHMI Desktop companion software provides a Troubleshooting Editor which can be used to set up the Troubleshoot scheme to suit the individual end user application requirements.

IHMI Functions button gives access to additional functionality such as data logging, recipe management and creation of new tag variables (such as sensor type, temperature display C or F, etc) for the controller. Data Logging function allows you to select parameters such as Process Temperatures, Set Points and other variables from your Watlow controllers to be continuously stored on the handheld at selected intervals. Logged data can be viewed on the handheld or transferred to a PC for later analysis using Microsoft Excel.

The Exit button allows you to exit the InstantHMI application program. You may then access other applications on the Palm through the silk-screened Home button, Calculator button etc.
