Application Task List Application task list includes tasks which are executed at power-on and global tasks which are executed irrespective of the active screen. Screen Task List The screen task list includes tasks, which are executed only when that particular screen is active. Different set of tasks can be executed “before” the screen is shown; “while” the screen is being shown and “after” the screen is closed. Touch Screen Task A list of tasks can be created which are executed upon touching an area (button) on the Prizm screen. Different set of tasks can be executed when the button is “pressed”; while the button is “held down” and “when” the button is “released”. Special tasks allow creating buttons such as numeric inputs, alarm management, data logger management etc. Easy events logging and trend tracking Upto 2 MB of FLASH memory can be alloted to give you the memory you need for historical event logging and trending. Bitmaps / Wizards Bitmaps can be imported into the application and displayed on the Prizm screens. In addition, several wizards are supported to create commonly used objects such as Analog meters, Lamps, Buttons and Bar graphs. Screens The Number of screens, which can be defined, is constrained only by the unit memory. Various types of objects can be defined on the screen such as plain text objects, Data display (coil status, register value, value dependent text), Data entry objects, Alarm objects, Bitmaps, Wizards, Date / Time etc. Date Entry Data entry objects can be placed on screens. Each data entry object can have high / low limits and math function associated with it. Various types of data formats are supported including floating point data. Alarms Up to 256 real time alarms can be defined in Prizm. Alarms can be displayed on the screen in formatted (user-defined) columns. Alarms could also be logged and historical alarms can also be displayed. Buttons can be created to acknowledge alarm, print alarm, view next / previous alarm etc. Multilanguage / Unicode Support All the languages are supported in the Prizm unit. The user can now display messages, alarms in any regional language. All Windows® fonts can also be used in an application. Recipes Recipes data is stored in the Prizm memory. With one button stroke, a set of data can be downloaded to the PLC. Once in the local memory, the recipes data can be edited using simple data entry objects. Dual Port Support Prizm series has two communication ports. One port is used for connecting to a PLC. The other port is used for programming of Prizm unit, printing screens, connecting to third party serial devices (barcode readers, printers etc.) or to connect to another PLC or drive. USB Port Prizm290 has USB port that can be used as programming port. Ethernet Port Prizm units (except PZM-230) can have an Ethernet port. It can be used to connect to a PLC and monitor machine / process status from remote locations. The Ethernet port can also be used for remote programming of Prizm.
