Neil,
First:
You have to install GPS system in your MTK workstation (you may need to
change the system definition) this will synchronize your IA stations to
GPS clock

Second:
You take a RJ45/RJ45 cable from time strobe converter (it looks like a
small hub) to Triconex chassis Ethernet port (NET1 OR NET2) but this
port must be defined in Tristation as time synch port this will
synchronize your Triconex with same GPS clock that IA is synchronized
with

Alex,
     Excuse my ignorance, but does your GPS Solution with network sync
synchronize the foxboro MTK with an external atomic clock?  
    I used to be a big fan of Chicago's song "Does anybody really know
what time it is?  Does anybody really care?" but now everyone I work for
wants to know down to the milli-second so I guess I'd better care.

Alex,
With this solution, what happens concerning time changes from the 
TriStation whenever  the TriStation down loads changes to the Trident?
If 
the TriStation is not in time sync, it is apparently going to change the

time to something else that is not desirable.

Neil,

Re: I/A Series to Triconex Time Synchronization

The I/A Series TSAA FDSI FBM can synchronize the Tricon or Trident to
within roughly 25ms of the CP's time. This is a standard part of the
driver.


Re: I/A Series and GPS
You can buy and install our GPS solution. There are two options:

1) With time synchronization network and
2) Without time synchronization network.

The former case keeps the CP270s (and FCMs for ZCP) within +/- 0.5 ms of
the Master Timekeeper (MTK).

The latter case keeps workstations within 50ms of the MTK via NTP. CP's
though use the older I/A Series time mechanism and are guaranteed to +/-
1s relative to the MTK.


The gist of this is if you use our GPS without the time synchronization
network, you can synchronize the CP/Triconex pair quite closely to each
other (25ms) and they will be no more than 1s from the MTK.

There are other options available, but these are off-the-shelf.


Does this help?

Subject: [foxboro] Recommendations for setting I/A DCS and Triconex
TriStation time by GPS or similar manner?

We are looking for reliable, cost effective and easy to support solution

options that can be purchased to set V8.4.X (windows) I/A DCS time and 
Triconex TriStation time by GPS (or some other means of automatic
standard 
time setting).  Does anyone have suggestions/recommendations?
As a second question, does any one have a good solution to sync Triconex

TriStation time with I/A DCS time?

The most important need is to have the Triconex system set to the same 
time as the I/A DCS.  The first thought for doing this would be to have 
the DCS toggle a bit at a set time each day, and the Trident stations 
reset their time to the designated time every day.  However, one of the 
problems with this is that the TriStation apparently resets a Trident 
station to its time every time it down loads a change to the station. 
Thus, unless there is a way to turn off this feature, we are going to
need 
a way to keep one or more TriStations time synced with the DCS.
