1 7001RC System Description
The hopf system 7001RC was developed as a central clock system to undertake complex
time distribution tasks. It can provide interfaces for industrial computers, process control
systems and control devices, synchronize networks, control slave clocks and much more. All
'RC-Function Boards' of the system 7001RC (with the exception of the control board
7020RC) are hot-plug-compatible and as such can be disconnected from and reconnected to
any point on the operating system at any time, without affecting the operation of other
'RC-Function Boards'.
The system’s 7020RC control board communicates, via the internal system bus, with the
'RC-Function Boards' that are integrated into the system, and simultaneously monitors these
boards for faults.
Due to its modular structure the system can be configured individually for each application
and is easy to upgrade or modify if the application conditions change.
hopf 'Function Boards' for 19" systems can also be integrated into the system alongside the
'RC-Function Boards'.
In addition to the standard quartz generator, the 7020RC control board can also be equipped
with an oven-stabilized OCXO quartz generator, which increases the accuracy of the system
when operating in independent mode. See Chapter 8 Technical Data System 7001RC .
Some base functions of the system 7001RC
Operation via remote software
Hot-plug compatibility
Display blanking to increase the lifetime of the display
Sync-OFF timer (reception failure) for operation without error messages, even in
difficult reception conditions
Redundant, multiple verification of the synchronization signal for error-free and leap-
free signal evaluation
Maintenance-free, buffered back-up clock for three days
Error monitoring of the integrated 'RC-Function Boards'
System 5000 (Switch-Box) control for redundant systems
True Time Server functionality – also upgradeable in the future
Extension options
Evaluation of several synchronization sources (multi-source system)
7020RC control board can be extended with OCXO as quartz base to provide very
high accuracy in independent operation
Redundant power supply for the system 7001RC via 2 power supply units and a
coupling card for interconnecting 2 power supply units
Additional power supply for internal line voltage for the 'RC-Function Board' 7406RC.
Extension of the 1/1 19" rack by an additional 3U (height units) to 6U.
Customer-specific system adaptations for bespoke project solutions.

System example: rear/connection side:
Up to 14 slots (including management board (LAN) 7050RC for system
7001RC) are available on a 3U rack for 'Function Boards' / 'RC-Function
Boards' with 4HP faceplate width. Where 'Function Boards' or 'RC-Function
Boards' with 8, 12 or 16HP width are used, the number of slots is reduced
accordingly.
1.1.2 Display
The display consists of a two-line VFD display (Vacuum Fluorescent Display) with 2x40
characters.
For technical reasons the VFD display has a limited lifetime. Luminosity is
reduced over the time of operation. In order to extend lifetime (luminosity)
the display can be switched to blank.
See Chapter 4.1.1.6.1 Bit 7/6, Display Control.
For a description of the display functions see Chapter 3.3 Display after System Start /
Reset (Firmware).
1.1.3 Keypad
The alphanumeric keypad with 6x7 layout provides menu-driven operation of the clock
system.
The keypad is a membrane keypad and must not be operated with sharp or
pointed objects (fingernails, pens etc.).
For keypad operation see Chapter 3.6 Keypad Functions.

1.1.5 7001RC Bus
The system bus is located inside the system 7001RC. This consists of a bus board with VG-
ledges via which the 'Function Boards' or 'RC-Function Boards' are connected to the
7020RC control board.
The system bus provides:
communication between the 7020RC control board and the 'RC-Function Boards'
transmission of the regulated second pulse (PPS) for synchronization of the data output
of implemented 'RC-Function Boards'
distribution of the regulated DCF77 pulse generated by the 7020RC control board
power supply for the installed boards

1.1.6 Differentiation between 'Function Boards' and
'RC-Function Boards'
'Function boards' are mostly simple output boards that do not possess their own
“intelligence”. Generally, the information to be output is supplied from any desired signal
source. It is not mandatory for these boards to have a system bus. However, most of these
'Function Boards' can pick up the information available on the system bus (PPS pulses,
DCF77 pulse) and output them in a board-specific hardware format. Any parameterization
that is possible is carried out directly on the 'Function Boards'.
The term 'RC-Function Board' is used to describe boards that can be clearly identified in the
system due to their “intelligence“ and which receive their parameterization via the system
bus. All parameters that are specific to 'RC-Function Boards' are stored in the system.
Board type Explanation
'Function Board' Can not be integrated into the system 7001RC via the system
menu.
Board numbers are not allocated.
Functions immediately after installation in the system 7001RC,
provided that any necessary additional wiring to its slot is in place.
Can not be configured via the BOARD menu.
'Function board' settings take place directly on the boards via
jumpers and/or DIP switches.
Since 'Function Boards' are not monitored by the system 7001RC,
they are also unable to trigger an error message.
'RC-Function Board' Function boards are:
ointegrated/deleted
oparameterized
oread
omonitored
via the system menu.
Clearly identifiable via 'RC-Function Board' type and board
number set.
With the exception of the board number, no further settings are
made directly on the 'RC-Function Boards'. All settings are made
exclusively via the system keypad or the remote software.
Triggers an error message in the system 7001RC when a fault
occurs on the board.
Have no function until they have been completely integrated into
the system 7001RC via the menus.
Only 'RC-Function Boards' (recognizable via the identification 'RC' on the
handle) can be implemented in the system 7001RC.
Exceptions: passive 'Function Boards', which do not communicate with the
system bus.
If other board types (e.g. from the 7001DCF77/GPS system) are installed in the
system 7001RC, this can cause damage to the board and the system 7001RC.

1.1.7 'Function Boards' / 'RC-Function Boards' Slots
Up to 14 further 'Function Boards' / 'RC-Function Boards' with 4HP front panel width can be
installed in the system 7001RC alongside the 7020RC control board, depending on the
space requirement of individual system components such as, for example, a second power
supply unit or wider front panel(s).
The first bus slot next to the power supply feed is reserved exclusively for the
7020RC control board because of the wiring to the display/keypad.
In principle the slot for each 'Function Boards' / 'RC-Function Boards' is freely selectable.
A free slot is required for the installation of a new 'Function Boards' / 'RC-Function Board'.
This must meet the following conditions:
The slot width must be at least the same as the front panel width (e.g. 4TE, 8TE ...).
A VG ledge with board guide bars must be installed in the system bus and be
available at this point.
If not all slots are provided with VG ledges and board guide bars but these are required for a
system extension, they can usually be retrofitted. Please make contact with
hopf Elektronik
GmbH for this purpose.
Limitations to free slot selection:
It should be noted that in certain circumstances 'Function Boards' /
'RC-Function Boards' require special wiring to their slot, e.g. additional power
supply or signal wiring. Due to this additional wiring, these 'Function Boards' /
'RC-Function Boards' are tied to the correspondingly prepared slot.
Slots with additional wiring can be seen on the respective system drawing.

1.2 Hot-plug Compatibility of the System 7001RC
Hot-plug describes the connection and removal of system components whilst the system is
operating, without the need to pause or switch off the complete system. This guarantees
interruption-free operation of the system.
The hot-plug compatibility of the system 7001RC is limited exclusively to the following
components:
'Function boards' / 'RC-Function Boards'
The 'Function Boards' / 'RC-Function Boards' available for the system 7001RC are hot-plug
compatible.
Exception:
The 7020RC control board is not hot-plug compatible due to its system
control function.
In order to prevent faults on connected systems it is recommended to disconnect the cables
of the 'Function Boards' / 'RC-Function Boards' during removal or installation of the board.
Power supply unit on systems with redundant power supply units (option):
Power supply units on systems with redundant power supply units, which are connected via
a coupling card, are hot-plug compatible. In this configuration, one of the power supply units
can be changed whilst the system is running without restricting the functionality of the
system, provided that the remaining power supply unit is functioning correctly. This ready-to-
go power supply unit takes over the power supply without interrupting the system voltage.
1.3 System Operation via Remote Software
All system parameterization for the 7020RC control board and 'RC-Function boards' can be
carried out from a PC, connected via a serial interface, using remote software.
Keypad operation is blocked whilst the system is being operated via remote software.
Equally, it is not possible to build a connection from the remote software to the system
7001RC whilst the system is being operated via the keypad.
For further information see Chapter 3.7 Operating with Remote Software.
1.4 Clock Variants in the System 7001RC
The following describes the clock variants that are possible in the 7001RC.
1.4.1 Radio-Controlled Clocks
When operating as a radio-controlled clock, the system 7001RC is synchronized by means
of a connected antenna device. The data received is used to calculate the current time/date
and to control the internal quartz base.

1.4.2 Quartz-Controlled Clocks
Quartz-controlled clocks are independent clocks, whose internal quartz base is not controlled
by an external synchronization signal. The accuracy of these clocks depends directly on the
quality of the installed quartz and the precise setting of a quartz control value. The accuracy
of the quartz clock can be increased by the optional installation of an oven-stabilized quartz
(OCXO).
The quartz control value relevant for the accuracy of the system can be set manually. See
Chapter 4.1.2.2 Quartz Control.
Identifier on
standard display Synchronization source
QUARZ Quartz-controlled clock. Synchronization from the quartz generator
on the 7020RC control board only.
QUARZ+ Not implemented
1.4.3 Master Systems
Master clock systems may be defined as clock systems that are able to synchronize other,
subordinate clock systems.
1.4.4 Slave Systems
Slave systems may be defined as systems, which are synchronized by one or more master
systems. The accuracy of a slave system is directly dependent on the accuracy of the
master system.
1.4.5 Single Source Systems
Single source systems are synchronized and controlled from a single synchronization
source.
Identifier on
standard display Synchronization source
GPS_M Synchronization via a GPS receiver
DCF_T Synchronization via a DCF77 pulse
MA_SL Synchronization via a serial Master/Slave-String from another
hopf
system
DCF_A Not implemented
1.4.5.1 Sync-Signal: GPS
Operating mode: GPS_M
GPS radio-controlled clock systems are synchronized via the time signal transmitted by the
GPS satellite. For this reason it is necessary to install suitable GPS antenna equipment.
Details about the GPS operating method are described in Chapter 9.1 GPS (Global
Positioning System).

1.4.5.2 Sync-Signal: DCF77
Operating mode: DCF_A
This operating mode is not implemented.
Synchronization via a DCF77 signal is carried out using a different function (see Chapter
1.4.7 Sync. Signal via Converter).
1.4.5.3 Sync-Signal: DCF77 Pulse
Operating mode: DCF_T
The DCF77 pulse is a digital pulse based on the DCF77 signal, which can be transmitted in
various signal forms (such as TTL, RS232, RS422, LWL...). The time information is
transmitted via the DCF77 pulse. This pulse can also be used to control the internal quartz
base of the receiver. For further information see Chapter 9.2.2.2 DCF77 Pulse (1 Hz).
Sample Configuration:
Synchronisation of the System 7010RC-Slave with DCF77 reception via an antenna
System.
The additionally implemented DCF77 receiver board (slot A7) is synchronized via the DCF77
antenna System and transfers an exact DCF77 pulse to board 7020RC-Slave being
successfully synchronized. Hereupon board 7020RC-Slave synchronizes and provides the
entire System with this time information.
1.4.5.4 Sync-Signal: Master/Slave-String
Operating mode: MA_SL
The Master/Slave-String is a serial
hopf data string, which can be supplied to the system via
converter cards in various signal forms (such as TTL, RS232, RS422, LWL...).
The time information is transmitted via the Master/Slave-String. The Master/Slave-String can
also be used to control the internal quartz base of the receiver. For further information see
Chapter 9.3 Master/Slave-String.
