1 GPS - NTP Time Server 8030NTS/GPS
By GPS time synchronization and the worldwide used time protocol NTP (Network Time
Protocol) the Time Server 8030NTS/GPS turns into a highly accurate NTP Stratum 1 Time
Server. It is used for the synchronization of computers and industrial networks.
The Time Server supports the following synchronization protocols:
•NTP (incl. SNTP)
•Daytime
•Time
•SINEC H1 time datagram (Activation Key necessary)
•IEEE 1588 Precision Time Protocol (PTP) (Activation Key necessary)
The Time Server is integrated into a compact DIN Rail housing and is characterized by its
easy and simple operation, although it offers a broad range of functions. Some of the prac-
tice-oriented functionalities are:
•Complete parameterisation via protected WebGUI access
All required settings for operation can be executed via a password proteded WebGUI
also giving an overview of the status of the Time Server 8030NTS/GPS.
•Monitoring of GPS antenna circuit
An error message is generated when there is a short circuit in the GPS antenna circuit
or an open antenna input.
•Automatic switch-over of summer/winter time (initial setting required)
After initial commissioning there is no user intervention for a correct summer/winter
time changeover for the following years required.
•Automatic handling of the leap second
Insertion of a leap second in UTC time is automatically recognised and executed by
the Time Sever 8030NTS/GPS.

2.3.4.1 MAC-Address for ETH0/ETH1
Each LAN interface is clearly identifiable on the Ethermet via a unique MAC Address (hard-
ware address).
The MAC addresses given for the LAN interfaces can be read in WebGUI of the appropriate
module or be evaluated via the hmc Network Configuration Assistant.
The MAC address for ETH1 is incremented hexadecimal by 1 to the MAC address of ETH0.
Example:
•MAC address ETH0 = 00:03:C7:12:34:59
•MAC address ETH1 = 00:03:C7:12:34:5A
The MAC address is uniquely assigned for each LAN interface by the company hopf El-
ektronik GmbH.
hopf Elektronik GmbH MAC addresses begin with 00:03:C7:xx:xx:xx.

3 Function Principle
This chapter describes the function principle of the Time Server 8030NTS/GPS and the inter-
nal relations between the different functional groups.
3.1 Block Diagram
•Internal Supply Voltage
The individual functional components are supplied with the required operating voltage
via the implemented power supply unit.
•Firmware Update
A H8 firmware update of the Sync Souce (here Module 8024GPS) is completey con-
trolled by Module 8030NTS.
The update file for Module 8024GPS is loaded into Module 8030NTS via LAN through
the WebGUI. Then Module 8030NTS performs the update of the Sync Source (here
Module 8024GPS) independently.
•Management
The entire control of the Sync Source (here Module 8024GPS) is done by Module
8030NTS. All data of the Sync Source, indicated via WebGUI, are demanded cyclically
by Module 8030NTS from the Sync Source (here Module 8024GPS) or if necessary.
These data are then prepared for the display in WebGUI. After activation settings for
the Sync Source are transferred to the Sync Source immediately.
•High Precision Time
The Sync Source provides a high-precision time information and the according syn-
chronization status to Module 8030NTS. This time and status information is used for
synchronization of the NTP service and if applicable other signal generations running
on 8030NTS.

3.2 Function 8030NTS (WebGUI: Device)
The Module 8030NTS is the "heart" of the Time Server 8030NTS/GPS. A complete LINUX
operating system is running on this Module providing all functions such as NTP, WebGUI etc.
The Module also controls the connected Sync Source (here Module 8024GPS). Using the
high-precise time information of Module 8024GPS the NTP service running on Module
8030NTS is also adjusted with high-precision. Thus the Module 8030NTS is a very precise
NTP STRATUM 1 - Time Server.
3.3 Function 8024GPS (WebGUI: Sync Source)
The Module 8024GPS is in principle an independent Module with GPS receiver and its own
µProcessor. In synchronous status it provides a high-precise time information to the Module
8030NTS. The control of Module 8024GPS in this system is completely done via Module
8030NTS. Parameters required by Module 8024GPS or provided are entered into WebGUI of
Module 8030NTS or rather be output.
The Module 8024GPS has an own failsafe memory in which all required data for operation
after generation via WebGUI are stored.
As the data of the Sync Source for the WebGUI indication need to be received by the Module
8030NTS at first, it is no real-time indication in WebGUI.

4 System Behaviour
This chapter describes the behaviour of the system in special operational phases and condi-
tions.
4.1 Boot Phase
The boot process of the Time Server 8030NTS/GPS starts after turning on the system or a
reset.
During the boot process the Module 8030NTS boots its LINUX operation system and is there-
fore not available via LAN.
The end of the boot process is reached when the green NTP LED is shining and thereby
indicates that the NTP service on Module 8030NTS has been started and enabled. The boot
process lasts approx. 1-1.5 minutes.
4.2 NTP Adjustment Process (NTP/Stratum/Accuracy)
NTP is a regulation process. After start of the NTP services, automatically processed during
booting, the Time Server 8030NTS/GPS requires approximately 5-10 minutes after synchro-
nization of the Sync Source (Status "SYNC") until NTP is set to the high accuracy of the Sync
Source (here Module 8024GPS) and reaches the optimized operation condition of STRATUM
= 1 and ACCURACY = High.
The decisive factors here are accuracy of the synchronization source and the appropriate syn-
chronization condition of the Sync Source.
4.3 Reset-(Default) Button
The Time Server 8030NTS/GPS can be reset by the Reset-(Default) Button behind the front
panel of the board. The Reset-(Default) Button is accessible with a thin objective through the
small drilling in the front panel.
The button triggers different functions depending on how long it is pressed:
Duration
Function
< 1 sec.
No action
1 - 9 sec.
After releasing a systemwide hardware reset is triggered
>= 10 sec.
After releasing a FACTORY DEFAULT followd by a REBOOT is
triggered after approx. 10 seconds

4.4 Firmware Update
The Time Server 8030NTS/GPS is a multi processor system. For this reason a firmware up-
date always consists of a so called Software SET including up to three (3) program releases
defined by the SET version needed to be loaded into the board.
Module 8030NTS (WebGUI: Device):
1x Image Update
1x H8 Update (optional –not in the standard device)
Module 8024GPS (WebGUI: Sync Source):
1x H8 Update
An update is a critical process.
The device should not be turned off during the update and the network
connection to the device not be interrupted.
All programs of a SET needed to be uploaded to ensure a defined opera-
tion condition.
The progam releases assigned to a SET version may be taken from the
release notes of the software SETs of the Time Sever 8030NTS/GPS.
4.4.1 Firmware Update 8030NTS (WebGUI: Device)
The general process of a software update of Module 8030NTS is described below:
For selection of the correct update set the identifier 8030NTS has to be
observed obligatory.
8030NTS can be recognized:
•By the label on the housing cover "8030NTS"
•In WebGUI at the Web-banner "8030NTS"
The firmware update 8030NTS has to be performed as a SET.
The software package contained in the file package hopf8030NTS_GPS_SET_vXXXX.zip has
to be unpacked. The following steps have to be executed in the following sequence:
1. Image Update 8030NTS
2. H8 Firmware Update 8030NTS
3. H8 Firmware Update 8024GPS
