HW4 Software
 

The HygroFlex firmware version 4.1b or higher is designed for use with the ROTRONIC HW4 software. HW4 is available in the following versions:

HW4 Standard Edition: for single users.

  • Unlimited number of instruments (depends on capabilities of PC and available ports)

  • On-line display of the measured and calculated values (dew point or other) - limited to a single instrument at a time (instrument may have several probes).

  • Automatic retention of the most recent data in a temporary on-line buffer.

  • Logging of measured and calculated values to the PC (can be done simultaneously with local data logging).

  • Easy-to-read graphs and data tables.

  • Statistical data analysis: mean, standard deviation, minimum and maximum (off-line data only)

  • Data print-out (table or graph)

  • Automatic device/instrument recognition and identification

  • Device/instrument configuration

  • Adjustment / calibration of the HygroClip digital probes

  • Psychrometric Conversion Tool

  • Built-in security to protect against manipulation of recorded data

HW4 Professional Edition: meets the requirements of FDA 21CFR Part II / GAMP and allows multiple users, with either administrator or standard rights. On each single port (RS-232, USB or TCP/IP), HW4 Professional can monitor up to 64 instruments connected together in a multi-dropped RS-485 network. The number of such networks depends on the number of available ports.

  • All the functionality of HW4 Standard Edition

  • On-line display in a single graph of the data from multiple instruments and probes

  • Overlaying of several log files into a single graph

  • User Event Logging: automatically keeps track of user activity

  • Self Event Logging: automatically records eventual software problems to facilitate troubleshooting

  • Logger Event Logging: automatically records the data logger internal events and configuration changes.

  • Automatic creation of protocols detailing instrument configuration changes, log function programming and probe adjustments.

  • Password protected log-in

  • Indication of an alarm condition when displaying log file data

  • Indication on the PC of an alarm condition, printing of a report or sending an e-mail (MAPI or SMTP) 1

  • Automatic downloading and archiving on the PC of the files recorded locally by a data logger 1

  • Automatic synchronization of the networked devices with the PC time 1

  • Device protection against unauthorized configuration / programming changes 1

HW4 Professional Edition can be installed on a file server 1 for simultaneous access by several users (limited rights).

1 Availability of this feature depends on the HW4 software release and on the firmware release of some devices.

HW4 Professional with OPC Server: this version includes all features of HW4 Professional while also providing OPC tags that can be enabled for each individual device communicating with HW4. This allows exporting and integrating the HW4 data with with practically any OPC client (requires configuration / programming of the OPC client by the user).

HW4 Validated: this version offers the same functionality as HW4 Professional with OPC server. Additionally, the “HW4 e-compliance Package” is available. This extensive collection of documents (including template of qualification documents) is designed to support the “regulated user” by qualifying/validating HW4-based solutions. The most current validated release of HW4 is v 1.2.1. Release 1.2.2 will be validated during the second half of 2006.

HW4 Professional Trial Version: this is a fully functional version of HW4 Professional, including the OPC server functionality. A compressed installation file (zip) can be downloaded free of charge from the ROTRONIC website at: http://www.rotronic.ch/downloads/feuchte_software.php?language=ch-en 1

Activation requires a product key which can be requested by filling a form on the ROTRONIC web site. A trial product key will be sent to your e-mail address. This must be entered in the registration form which appears when starting HW4 for the first time. After 30 days, the trial product key expires and HW4 can no longer be started.

HW4 Requirements:

Computer/Operating System Requirements:

The following are the minimum values required to install and run HW4 on a computer. It is highly recommended to exceed these values.

  • Processor: Pentium II, 450 MHz

  • RAM: 128 MB

  • Available hard disk space: 50 MB

  • Monitor: SVGA, 1024 x 768, 256 colors

  • Ports: one free serial (COM) port or one free USB port or Network Interface Card (Ethernet)

 Operating System Compatibility:

  • Windows XP, NT4 with SP 6a or higher

  • Windows 2000 with SP 2 or higher

  • Windows Server 2003

HW4 was written for the Microsoft .NET framework and requires this framework to be installed on the computer. The .NET framework offers significant improvements in the areas of networking and user security. When new software is being installed, the .NET framework also eliminates the potential problem of conflicting dynamic library files (DLL).
