The function returns an element for each Analog Function Block referenced in

the parameter you supplied to the function. The properties included in each
element are initially defined when the Analog Function Block is created. You

can write to them with the AnalogFBSet function. Table 45 describes these properties.
For more information on the AnalogFBSet function, see AnalogFBSet on page 9-14.

Table 45 AnalogFBGet Output Properties

Property Description

The index number assigned to the Analog Function Block must be in the

range 0-32,767. As mentioned earlier, you can use the AnalogFBSet
function to create a new Analog Function Block, or to modify an existing

Analog Function Block. If you do not specify an index number in the

parameter you supply to AnalogFBSet, the function will create a
new Analog Function Block using the first available index number.
If you specify an index number that is already being used, the function will

overwrite the configuration of the Analog Function Block using that index
number with the settings defined in the parameter.

A timestamp indicating the last time the configuration of the Analog

Function Block was updated. This timestamp uses the following format:
YYYY-MM-DDTHH:MM:SSZ

The first segment of the time stamp (YYYY-MM-DD) represents the date

the configuration of the Analog Function Block was last updated. The

second segment (THH:MM:SS) represents the time of day the configuration
of the Analog Function Block was last updated, in UTC (Coordinated

Universal Time).

UTC is the current term for what was commonly referred to as Greenwich

Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich

England, which lies on the zero longitudinal meridian. Universal time is
based on a 24 hour clock, therefore, an afternoon hour such as 4 pm UTC

would expressed as 16:00 UTC. The Z appended to the timestamp indicates

that it is in UTC.

For example, 2002-08-15T10:13:13Z indicates a UTC time of 10:13:13 AM

on August 15, 2002.
