Chapter 1 Installation
GPS Antenna Install the GPS antenna with a clear view of the sky (do not install the antenna
where objects can obstruct the view of the antenna to the sky). If an antenna is
installed with a limited view of the sky, the GPS receiver can have a low satellite
lock count, or be unable to obtain a lock. A limited view of the sky can cause
inaccurate time synchronization.

Microsecond = 234567
Time.UTC This is the current UTC in microseconds since the time base. The time
origin is based on all versions of RSLogix 5000 software or the Studio
5000 environment. See the example code for how this is used to time
stamp events in sequence-of-events (SOE) modules in RSLogix 5000
software versions earlier than 18.00.00.
Example:
02 April 2014
14:12:41
UTC = 87277992127872
Time.CST Displays the current CST of the local rack (depending on the CST
master clock) in microseconds.
Example:
CST master clock running for 1 hour
CST = 3600000000
Time.CSTOffset Displays the difference between the UTC and CST in microseconds.
Use this to set the wall clock in the Logix5000 controller in RSLogix
5000 software versions earlier than 18.00.00. Click this link to see

GPS.GPSLock Indicates if the GPS receiver has lock (if GPS is the time source). 0 = GPS receiver does not have lock
1 = GPS receiver has locked onto sufficient satellites
GPS.AntennaOK Indicates if the GPS antenna is connected and is operational (if GPS is
the time source).
0 = The antenna is either not present or is faulty
1 = The antenna is connected correctly and is operational
GPS.HDOPOk Horizontal Dilution of Precision (HDOP) occurs when there are
sufficient satellites in lock, but two or more satellites occupy similar
positions in the sky (therefore decreasing the number of effective
satellites).
0 = HDOP is currently active
1 = HDOP is not active
GPS.PPS The pulse per second toggles at the exact moment the second
changes and the microseconds are zero.
Note: because the actual RPI is 50 ms, the accuracy is lost in the input
image.
0 = It has been more than 100 ms since the rollover pulse of the
last second
1 = It has been less than 100 ms since the rollover pulse of the
last second

IRIGYear When the module has an IRIG-B time source, the year is not passed
over IRIG-B. Enter the current year here in the output image.
Example:
30 April 2014
IRIGYear = 2014
UTC_Offset The UTC_Offset is used only when the time source is IRIG-B, and PTP
output is enabled.
IRIG-B provides the UTC time, while PTP requires International
Atomic Time (TAI). The difference between the two is the UTC offset.
Example:
30 April 2014
UTC_Offset = 35
Be sure to verify the current UTC offset. The UTC offset changes
approximately every 18 months.
