IOLAN SDS/SCS/STS User’s Guide, Version 3.6

Time

Overview

You can set standard and summer time (daylight savings time) in the IOLAN. You can specify the
summer time settings as absolute, on a fixed date and time, or relative, on something like the third
day of the third week at this time in June.

Functionality

The IOLAN has a real-time internal clock, allowing the date and time to be set and viewed. It will
maintain the time over a short power outage and after reboots of the IOLAN. If you do not set the
time, it will start the clock at the factory set time.

When you set the IOLAN’s time, the connection method and time zone settings can affect the actual
internal clock time that is being set. For example, if you are connecting to the IOLAN through the
DeviceManager and your PC’s time zone is set to Pacific Standard Time (GMT -8:00) and the
IOLAN’s time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN’s time is actually three
hours ahead of your PC’s time. Therefore, if you set the IOLAN’s time to 2:30 pm in the
DeviceManager, the IOLAN’s actual internal clock time is 5:30 pm. This is the only configuration
method that interprets the time and converts it between time zones, as necessary.

string as the trap sender. The IOLAN supports SNMP traps for restart and
SNMP community authentication error.

the IOLAN. Up to four trap hosts can be defined.
