1 Slave Clock Control Board 7406RC
RC Function Board 7406RC is a Slave Clock Control Board for controlling two lines (clock
chains) with clocks operating on a pole-changing pulse basis or DCF77 time code
clocks.
It is designed for the central
hopf clock System 7001RC in eurocard size with a 4HP/3U
front panel.
After the once-only set-up of the clock equipment the system operates
maintenance-free.
The pulse output of the two lines is monitored so that, in the event of a fault or pulse
failure, an error message can be transmitted.
In the event of a fault in pole-changing mode, the current time of the slave clocks
is stored, such that after the fault has been removed or when the equipment is re-
started, the last-transmitted time is available and the slave clocks are re-set
independently.
The pulse lengths are adjustable in pole-changing operational mode.
A constant voltage supply source external to the system 7001RC can be
connected to RC Function Board 7406RC, to control and supply power to the slave
clocks (see Chapter 9 Technical Data).
RC Function Board 7406RC can synchronise self-setting DCF77 time code clocks
with the DCF77 data telegram via the line cables. If these clocks have a power
supply independently from the System 7001RC they continue to run whilst there is a
fault (DCF77 data telegram failure).
The summertime/wintertime changeover points are executed in conjunction with
RC Function Board 7406RC.
The time basis of the lines can be transmitted in local time or UTC time.
Due to its hot-plug capability, the Board can be removed from and re-connected to
the running 7001RC system at any time and at any point, without affecting the
function of other system boards. However, to provide the power supply to slave
lines, it can be fixed to a connection slot in system 7001RC by means of additional
internal wiring.
Slave Clock Control Board 7406RC is configured via the
hopf System 7001RC
display / keyboard or via
hopf _RC remote software.
Monitoring for insufficient line voltage

2 Clocks in Pole-Changing Pulse Operation
In pole-changing operation, lines transmit every second for second lines and every minute
for minute lines, alternately a positive or negative voltage pulse with the set pulse length.

3 DCF77 Time Code Clocks
In DCF77 time code operation, lines transmit a DCF77 time code signal, changing pole on
every second change. The DCF77 time code signal is coded according to the period of the
zero volt position, 100msec (= logic 0) and 200msec (= logic 1).

5 Implementation of the Board 7406RC in the
System 7001RC
All RC function boards are individually parameterized from the system 7001RC.
Every RC function board is uniquely identified via the board type and an
assigned board number (1-31)
The following steps are necessary for implementation:
Identification of the board numbers available
Setting up of the board number with the DIP switch on the board 7406RC
Installation of the board 7406RC in the system 7001RC
Parameterization of the board 7406RC
Activation of the board 7406RC via the system 7001RC
5.1 Identification of the Board Numbers available
The board numbers allocated so far can be displayed via the SHOW ALL ADDED SYSTEM-
BOARDS menu. The board numbers that are not listed for this board type are available for
the new board.
Boards that are available in terms of hardware, but which have not yet been
activated via the system menu, are not listed in the SHOW ALL ADDED
SYSTEM-BOARDS menu. (The "SEND" LED of these boards does not
flash when in operation.)
In order to identify the set board number, these boards must be made
available externally, in order to identify the set board number from the DIP
switch setting.
5.2 Set the Board Number
In order to clearly identify the board in the system 7001RC, the board number must be
defined via the DS1 DIP switch bank. The board number is set as Hex code on DS1. Switch
8 is the lowest value bit and switch 1 the highest value bit. The inscription on the DIP switch
housing serves to identify switches 1-8. Board numbers from 1 to 31 can be setup, board
numbers outside this range are not recognized by the system 7001RC.
Under no circumstances may two boards of the same type with the same
board number be embedded in one system 7001RC. This leads to
undefined errors on both boards.

5.3 Installation of a new Board 7406RC in the System 7001RC
In order to install a new board 7406RC, a free extension slot (slot with board connectors and
VG strip installed in the system bus) must be available. This information can be obtained
from the associated specific system drawing.
If no free extension slot is available, this can usually be retrofitted. Please contact
hopf
Elektronik GmbH.

5.4 Parametrize / Activating the Board 7406RC in the
System 7001RC
The following steps are required to activate the board:
To avoid undesirable output behaviour of the board it is first parameterized
and then activated by switching it into the monitoring system.
In the BOARD-SETUP menu, sub-heading ADD SYSTEM-BOARDS, log on the
newly installed board.
In the BOARD-SETUP menu, sub-heading SET SYSTEM BOARDS PARAMETER
parameterize the board. (Chapter 6 Administration of the Board 7406RC)
In the BOARD-SETUP menu, sub-heading SET SYSTEM BOARDS TO
MONITORING-MODE OR IDLE-MODE integrate the newly installed board into the
monitoring system.
The menus:
ADD SYSTEM-BOARDS and
SET SYSTEM BOARDS TO MONITORING-MODE OR IDLE-
MODE
can be consulted in the technical specification of the system 7001RC.

In order for the system 7001RC to accept the newly configured parameters,
is the configured menu and the following parameter menu of SET SYSTEM-
BOARDS PARAMETER menu be confirmed by pressing the ENT key.

6.2.2 Bit 6 – Slave Line 2 as Minute or Second Line
For pole-changing pulse operation.
In this mode the two lines of Board 7406RC are controlled as either:
2 separate minute lines or
1 minute and 1 second lines (for clocks with separate second line)
Bit 6 = 1 2 independent minute slave lines
Both lines are used to control minute slave clock chains.
The Board occupies two line numbers in the system.
Bit 6 = 0 1 minute line and 1 second line
The 2nd line of the Board is used to control the seconds’ line.
With this setting Board 7406RC occupies only one common line number in
the system.
6.2.3 Bit 5 - Summertime/Wintertime Changeover
For pole-changing pulse operation.
This function defines the behaviour of the lines on ST/WT changeover.
Bit 5 = 0 1 hour - stop (1h) on ST WT changeover
The minute lines wait 1 hour after the changeover from summertime to wintertime.
The line is re-set on changeover from wintertime to summertime.
In order to prevent a data overrun, this function is automatically activated for
the minute lines in 24 hour operation, irrespective of the parameter byte
settings.
Bit 5 = 1 Updating (11/23 h forerun) on ST WT
The minute lines are always re-set after the ST/WT changeover.

For the purposes of manipulation, the individual bits of the new byte are to be entered on the
second line using "0" and "1". The complete Parameter Byte must always be recorded and
confirmed with the ENT key.

6.3.1 Bit 7 – Fault Signal with Synchronisation Status System 7001RC
Faults are signalled via the drop-out of the alarm relay and transmitted as a common signal.
If no faults / errors are present the alarm relay is re-activated.
All faults are signalled via the 24-pin delta-ribbon socket (see Chapter 4.1 Front Panel
Components):
See Chapter 7 Faults and Causes of Faults for possible error messages.
The common signal can be extended with the fault signal "No synchronisation of the
complete system" with Parameter Byte 02; Bit 7.
Bit 7 = 0 Radio synchronisation included in common fault signal
Bit 7 = 1 Radio synchronisation not included in common fault signal

6.3.2 Bit 6 – Line Operating Modes
Function Board 7406RC can be configured to operate clocks with pole-changing pulse
operation or DCF77 time code clocks.
Bit 6 = 1 For pole-changing pulse operation
Bit 6 = 0 For DCF77 time code clocks
In DCF77 time code mode 2 lines are available for the slave clocks.
6.3.3 Bit 5 – Line Time Basis
For pole-changing pulse operation and DCF77 time code mode.
The line output time for clocks is set up with the following function:
Bit 5 = 1 Local time output with any ST/WT changeover points
Bit 5 = 0 UTC time output without ST/WT changeover points
