PEN-DRIVE OPERATIONS
UniRec can perform both, File Read and File Write, operations on the Pen Drive. The File Read Operation facilitates
assigning user defined names to each of the connected Device channels while the File Write operation allows copying the
Process Value records (stored inside the internal memory of UniRec) onto the Pen Drive for subsequent reading in Excel
Sheet. The two file operations are described in detail in the following pages.
File System for Read Operation
UniRec continuously monitors and updates the Process Values (PVs) for each Device channel. The Process Values are
displayed on the front panel 2 Rows LCD display. The Upper Row displays the channel name while the corresponding PV
and measurement Units are shown on the Lower Row.
UniRec supports up to 30 single or dual channel devices. In ‘Device Configuration’ setup mode; the user needs to enter
the Device Number, the Device Type and the Device Communication ID.
UniRec assigns default channel names depending upon the device number assigned by the user (in ‘Device
Configuration’ set-up mode) and the numbers of channels (1 or 2) belonging to the selected device type. Refer following
examples for clarification.

The user can, however, assign a more meaningful name (such as Boiler Pressure, Oil Temperature, etc.) to each device
channel for easy identification of the process parameters that are being measured and displayed.
