Trap	The trap receiver is the network management system (NMS) that should
	receive the SNMP traps. This NMS must have the same SNMP community
	string as the trap sender. The IOLAN supports SNMP traps for restart and
	SNMP community authentication error.

Internet Address Defines the hosts (by IP address) that will receive trap messages generated by the IOLAN. Up to four trap hosts can be defined.

Field Format: IPv4 or IPv6 address

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.
