Operating System: Windows 2000 (Professional and Server), Windows Server 2003, Windows Server 2008, Windows XP Professional, Windows Vista Business or Vista Ultimate with IIS (Internet Information Server) installed. (See notes 1 and 2 below.)
IIS (Internet Information Server) installed on the Project Node. The WWW Service (web Server) must be installed and running. ASP (Active Server Pages) enabled. The SCADA nodes do not need IIS.
SMTP Server (optional, not recommended). The SMTP service is not needed on the Project Node if using Email Alarm Notification, Email of Scheduled Reports or MAIL commands. WebAccess normally uses an external SMTP Server (for example the corporate email server or and ISP) to forward email. Optionally, you can allow the Project node to forward email directly.
NTFS File System - NTFS provides Security and it is faster. FAT provides no security and is not appropriate for the Web Server (Project Node).
Microsoft Licensing will limit the number of clients connecting to IIS. The Limit is 10 simultaneous connections in Windows 2000 and XP Professional. In Windows 2000 and XP Server versions, the limit is dependant on your license (it can be unlimited). Vista Business is unlimited
Hardware: Pentium III, Pentium IV, Celeron or Athlon processors are recommended for the Project Node and SCADA nodes. SCSI Hard Drive, SAN or other large cache storage recommended if Data Logging.
Network Addressing: Fixed IP Address or network address. See section About Addresses for more information.
Web Browser: Optional. Needed for configuration tool. Microsoft Internet Explorer 6.0, 7.0, or later. (ASP enabled) Medium Security Zone setting for safe browsing.
Display Resolution: (Optional although a Display is recommended). 1024 x 768 or higher (recommended). Lower resolutions also supported.
Communications Service: Microsoft TCP/IP Protocol.
Communications Speed: T1 or DSL is
(33 Kb/sec, 56 Kb/sec, 128 Kb/sec and ADSL supported)
For Windows 2000, 2003, XP and Vista, Standard Users (i.e. a member of the Power Users) can install and run the client. Restricted Users (i.e. a member of Users) cannot install and cannot run the Client.
Web Security: WebAccess supports Anonymous Access, Authenticated Access (Integrated Windows authentication) and Secure Communications including Certificates, Secure Sockets and Virtual Private Networks (VPN).
Firewall Security (optional): If using a connection through a Firewall, two additional TCP Ports assigned by your system administrator are required (the default are 4592 and 14592). These are in addition to Port 80, the HTTP port, which must also be opened (or a third port assigned for HTTP).
