Table 647 - Wall Clock Time Object Common Services
DPI Fault Object — CLASS CODE 0x0097
This object provides access to fault information within the device.
The following class attributes are supported:
5 Set / SSV
Date and Time
(Local Time)
DINT[7] –
Array of seven DINTs
Current adjusted time in human readable format.
DINT[0] – year
DINT[1] – month
DINT[2] – day
DINT[3] – hour
DINT[4] – minute
DINT[5] – second
DINT[6] – sec.
6 Set / SSV
Current UT value
(UTC Time)
LINT
Current value of Wall Clock Time. 64-bit µS value
referenced from 0000 hrs January 1, 1970
7 Set / SSV
UTC Date and Time
(UTC Time)
DINT[7] –
Array of seven DINTs
Current time in human readable format.
DINT[0] – year
DINT[1] – month
DINT[2] – day
DINT[3] – hour
DINT[4] – minute
DINT[5] – second
DINT[6] – sec.
8 Set / SSV Time Zone String
Struct of UDINT
SINT[Length]
This string specifies the time zone where the controller is
located, and ultimately the adjustment in hours and minutes
applied to the UTC value to generate the local time value.
TimeZoneString can be specified in the following formats:
o UTC+hh:mm <location>
o UTC-hh:mm <location>
hh:mm portion is used internally to calculate the local time, and
the <location> portion is used to describe the time zone and is
optional.
GMT is also accepted
Length of the Data array can be from 10 to 82.
Examples:
UTC-05:00 Eastern Time
UTC+01:00 Coordinated Universal Time
9 Set / SSV DST Adjustment INT The number of minutes to be adjusted for daylight saving time
10 Set / SSV Enable DST USINT
It specifies if we are in daylight saving time or not. Not internally
set. Needs user action.
11 Set
Current value
(local time)
LINT
Adjusted Local value of Wall Clock Time.
