Chapter 5. About the SI7 I/O Driver 57

Feature: Time/Date Stamp for Data and Alarms

Intellution version 7.x I/O drivers record the time and date when any of the following

events occur:

• The driver writes data to the process hardware.

• An error occurs.

The driver time-stamps the data and errors at the datablock level. To view time and

date stamps in the SI7 I/O Driver Power Tool:

Feature: Running as a Windows Service

Version 7.x drivers can run as a service under Windows NT or Windows 2000.

Running your driver as a service lets users log on and off the operating system

without shutting down the driver.

NOTE: The SI7 driver does not support running as a service when using SIMATIC

NET 6.0.

By default, an I/O Server does not run as a service. To set up the I/O Server to run as

a Windows service, you must register it as a service. During installation, the Setup

wizard automatically registers the server as a regular server process. To register it to

run as a Windows service, you must run the server on the command line, specifying

that you want to register it. Once the server is running as a service, you may need to

re-register it in certain situations, such as when you need to change the logon account.
