RSFieldbus Time Stamping Setup
Time stamping is defined as the ability to record events in function blocks with
the date and time of occurrence. Time stamping requires that devices share a
coordinated system time with all other transmitters on the H1 network. This
allows function blocks to record events, such as alarms and changes of state,
using a common time basis. The architecture for time stamping is done using
the following equipment.
The SNTP Time Server provides the system with a time source with which all
Fieldbus devices can record events. The RSFieldbus Server coordinates the
SNTP Time Server and the linking device using the IDShellHSE.ini file
located on the server. The linking device uses the time, provided by the SNTP
Time Server and directed by the RSFieldbus Server, and passes it to
transmitters on the H1 network.
SNTP Server Set Up On your SNTP server, edit the following settings to synchronize with your
local time:
1. Date
2. Time
3. Time zone
The SNTP Server must be on the same subnet as the linking device.
