1.2 Short description
The DLX was designed as a powerful device for the registration and processing of electrical impulses from energy meters, flow meters, heat flow
processors and similar devices. It is meant for installation in bulk energy
supply points, power station injection points, at special contract customers
and industrial premises. Load profiles, calculated values and spontaneous
events are processed and stored on the site. This data can be interrogated
by hierarchically higher processing devices via a number of interfaces.
• The direct serial service interface (RS232) can be used to read and pro-
gram the DLX via the programming software DLXPARA. Compatible data
retrieval software (e.g. SIGLON) can be used to read data on site.
• The data interface “Com1” (RS232, RS485, 20mA/CS, M-Bus or fiber-optic)
can be used to retrieve data on site via data retrieval software. Alternatively
an external modem can be connected (via RS232).
• The modem interface “Com2” can be used to connect via the internal mo-
dem (optional) to the public switched telephone network (PSTN or ISDN) or
LAN/Ethernet and data can be uploaded to a PC. In place of modem can
be use a second data interface (RS232, RS485, 20mA/CS, M-Bus or fiberoptic).
An optional PC-Card (backup memory) can be used to store the content of
the periodical buffers and the spontaneous event buffer as well as part of
the device parameters. This PC-Card can be read by compatible data retrieval software via standard card readers and a PC.
Load management (switching off and on of loads) can be realized on site
via external load management software, using the control outputs of the
DLX.

2.2 Block circuit diagram of modules
The block circuit diagram below gives an overview of the individual modules of the DLX.
Figure 2, Block circuit diagram of modules
13
Page 14
2.2.1 Description of the block circuit diagram of modules
The DLX has a modular design. It consists of the following modules:
• Power supply module
Converts the external auxiliary voltage (85VAC to 265VAC or 60VDC to
270VDC) into the internal device voltages (5VDC and 12VDC).
• Connection module
Input pulse signals and control signals are galvanically isolated from the
process via input modules and connected to the processor module. Pulse
output signals and control output signals are serviced via the relay module
and an output module.
• Processor module
The processor module controls all functions of the DLX. Apart from the micro controller it contains the internal program and data memory, a real time
clock and capacitors to bridge power failures. The displays and the keypad
are also connected to the processor module.
• Display module
Stored data can be displayed via the LC-Display. The LED display shows
the status of individual process signals. Commands to the micro controller
are entered via the keypad. The program protection switch, which is used
to protect the parameters of the DLX from alterations, is located on the inside of the display module.

3 Functional Description
3.1 Functional circuit diagram
The functional circuit diagram below shows and overview of the individual
functions of a DLX device.
Figure 3, Functional circuit diagram
15
Page 16
3.2 Data protection and safety
All individual storage cells of the DLX are checked continually:
• RAM memory:
All storage cells are tested at least once in every 24 hours. The memory
contents are first written to a safe place, then a number of different bit patterns (A5, 5A, 00, FF) are written and read back into each memory cell. Finally the original memory content is written back. If a defective memory cell
is detected (bit patterns from read and write operations are not identical),
an error message is shown at the display and the error notification relay is
activated. The error message is available for remote data retrieval.
• Firmware memory:
The content of the firmware memory is tested on an ongoing basis: a
checksum is calculated over the whole memory content. If a difference is
detected between the calculated checksum and the stored checksum, an
error message is shown on the display and the error notification relay is activated. The error message is available for remote data retrieval.
• Data memory:
Data for parameters, spontaneous events, reset events and for each registration period are stored in physically separate areas (sectors). When data
is written, the correctness of the write cycle is confirmed for each individual
byte of data by an additional read cycle. Additionally a checksum is calculated for each data set. When data sets are read, another checksum is calculated and compared with the stored checksum. The data set will only be
processed if both checksums are identical.
3.3 Program code
The program code (firmware) is stored in the firmware memory (Flash
memory). Program code can be loaded with a special software application
via the service interface. Therefore no change of EPROM is required for
firmware updates. Loading of a new firmware is only permitted in nonsecured certification mode (in this mode the unit is not certified and the
program protection switch is set to “Disable”). All internal memory will be
cleared and the factory settings (see page 95) will be activated.
3.4 Setting of parameters (Programming the DLX)
Parameter settings in the DLX can be altered via the programming software
DLXPARA or via the keypad (only certain registers), however only after entering a valid password. All modifiable values are differentiated into two
groups: programmable and settable (the list of all registers is contained in
Appendix B). On each change of a parameter of the device, the state of the
program protection switch on the backside of the display will be checked. If
programming is protected (e.g. after certification), then only settable values
can be altered. Modification of programmable values is only possible after
removing the certification seal. If relevant regulations exist, the device must
then be re-certified afterwards. Once the program protection switch is deactivated, all variable values can be modified.
16
Page 17
For programming of the DLX a PC needs to be connected to the V.24 service interface of the DLX. Programming of the DLX is only possible with the
programming software DLXPARA. For details of the programming software
please read the user manual shipped with the software.
Before setting (or changing) any parameters of the DLX a reset (to fac-
tory settings) should be executed. Modification of some parameters
(see menu item „Internal memory“, page 33) will cause the unit to
automatically erase the registration period buffers.
During the setting of parameters of a DLX the data retrieval is disabled due to reasons of data security.
3.4.1 Program protection switch
Figure 4, Program protection switch by housing for panel mounting
Figure 5, Program protection switch by 19”-rack
Before transferring any parameters to the DLX unit, the program protection
switch must be set to “Enable”. The program protection switch is located on
the underside of the display board of the DLX.
17
Page 18
Disconnect the supply voltage to the DLX before opening the enclo-
sure. Otherwise an accidental pull on the flat band cable can destroy
the memory content of the unit.
Always touch first the grounded (earthed) metal frame of the unit with
one hand to force equalization of voltage potentials. Avoid any contact with other possibly charged parts of the data logger unit when
changing the setting of the program protection switch.
• Housing for panel mounting:
to achieve access to this switch, the front panel of the unit must be unscrewed and flipped upwards. Please note that the front panel is connected
to the CPU board with a flat band cable. The program protection switch is
located in the lower right hand corner of the DLX and can be operated by
hand.
19”-rack:
To expose the switch the upper cover must be removed by loosening the
two screws at the back. After shifting the cover to the backside the parameter switch can be toggled using an applicable tool (e.g. plastic screwdriver).
• For more information see page 41.
The meaning of the inscriptions are:
• Set Enable: Setting of parameters is permitted, the symbol blinks in
the display.
• Set Disable: Setting of parameters is disabled, the symbol is shown in
the display
To refuse access to parameter settings to unauthorized persons, the front
panel should be sealed.

3.5.1 Pulse inputs
Pulse inputs and control inputs are subject to signal verification implemented in the software, i.e. pulses that fall short of a minimum period of
time are not processed. This period can be programmed separately for
pulse length and pulse interval length in the range from 10ms to 2000ms in
steps of 10 ms for all pulse inputs.
Incoming pulses are counted, multiplied with a programmable value between
1/1 and 99999999/99999999 (only positive values possible) and added to the
energy registers separated by rate (see Figure 6, Block circuit diagram of impulse processing). Weighting to the correct physical measurement values is
done with pulse multiplication factors (these express the meter and transformer constants).
The formulas used are as follows:
Meter with transformer:
– X, Y: Numerator and Divisor – no decimal places, 8 digits
W
X
: weightingvalueEnergy
=
Y
K R
×
– W: Transformer ratio
– R: Meter constant (e.g. Impulses/kWh)
– K: Reading constant (for optimized reading)
The transformer ratio is calculated as the ratio between primary and secondary voltages and currents.
Transformer ratio : W = U
prim/Usec
× I
prim/Isec
The reading constant usually has a value of 1 (reading in kWh or kvarh).
Example: Voltage transformer: U
Current transformer: I

The number of digits for energy register is set to 9 (for version 1.04.00 and
up). This includes digits to the left and to the right of the decimal point (e.g.
with one decimal place : 12345678.9). If an energy register exceeds the
value 999999999, it continues at the value 000000000 and a flag will be set
in the device status register (of that registration period).
All pulse inputs arrive in two separate energy registers and one pulse register:
• Cumulative register (settable), in which the meter reading of the supplying
meter can be adjusted for control and check purposes.
• Current (cannot be modified externally), which registers the flow of energy
since the last reset.
• Pulse register (control register, cannot be modified externally), counts all
incoming pulses from the related input without weighting.
Furthermore the energy increment since the end of the last registration pe-
riod is calculated for both registration periods (Tm1 and Tm2). By multiplication with the time factor, these values are converted into demand values.

The energy increment registers (and therefore also the demand registers)

Example: Registration period: Tm1 = 15 min.
Time factor: TF = 60/15 = 4
Energy increment: ∆E = 25 kWh
→ Demand: P = ∆E × TF = 100 kW

3.5.2 Analogue input (Signal current input)
A continuous signal current flow is applied to the signal current inputs (e.g.
0..20mA or 4..20mA). This current is proportional to the actual demand.
The method of calculation can use pulses or digital values to transmit the
data to the DLX (Main-)CPU.
Pulse: For firmware version up to 1.05.06: the signal current input (analogue input)
measures power in order to establish energy consumption. The power is
measured over short intervals, multiplied by the time and the result is summated. This sum is equivalent to the energy consumed. If the sum exceeds
a fixed limit value "W", a 25msec internal output pulse is triggered and "W"
is subtracted from the sum. "W" is designated the pulse weighting and is
set such that at maximum demand a pulse frequency of 20Hz or 16Hz
(pulse length: 25msec) is reached. The demand is measured via an external transducer that converts the measured demand to an injected current
(selectable ranges: 0 to 20mA or 4 to 20mA).
Maximum current:
0..20mA (:=20mA) 72000 pulses per hour (:=3600sec × 20Hz)
4..20mA (:=16mA) 57600 pulses per hour (:=3600sec × 16Hz)

Digital: For firmware version from 1.06.00 and up: the average value (50 scans per
second) will be send every second to the DLX-CPU: value 0 corresponds to
0mA (threshold: 0,1mA), value 819 corresponds to 4mA (threshold: 4,1mA),
value 4095 corresponds to 20mA. For setting of the offset (0mA or 4mA)
use the software DLXPARA.
Note: Summation of the digital values is not possible!
3.5.3 Summation registers
The weighted pulses of all inputs can be totalled in up to 4 total registers
(with positive or negative sign):
= Σ kn × E
Total
i
n
kn : sign for input n, where: k = 1 or k = 0 or k = -1
En : Energy value at input n, where n = 1 … 16
22
Page 23
Depending on the sign, the incoming pulses are totalled in a positive or a
negative register. In the case of a simple sum (only positive inputs) the
positive register contains the sum and the negative register contains the
value 0.
In the case of frequent changes of the direction of energy flow (e.g. between export and import forward/backward), the hysteresis (slack) can be
used to activate the function “Differential total calculation” (for energy registers only). Here pulses will only be added to the positive or negative energy
registers once they have exceeded a minimum amount of energy after a
change of energy flow direction. The function of the hysteresis is one of an
intermediate storage register. Each pulse in positive direction will increase
the value of that register, whereas each pulse in negative direction will decrease its value. Pulses only appear at the output of the hysteresis register
once its programmable maximum content is exceeded in either direction.
An integrated energy direction pointer ensures correct output to either
“positive” or “negative” target registers. The purpose of the hysteresis register is to prevent unnecessary totalling of pulses in the “positive” and “negative” registers, when the flow of energy in both directions is almost in
balance. A meaningful guideline for the content of the hysteresis is double
the sum of the absolute value of all weighted inputs of the related total register.
Example:
Result with
Total Energy
Hysteresis = 0 kWh Hysteresis = 4 kWh
Export (+) 100 kWh 100 kWh 98 kWh
Import (-) 2 kWh 2 kWh 0 kWh
In addition, the energy increment since the end of the last registration period is calculated for both the positive and negative registers of each sum
and for each registration period (Tm1 and Tm2). If the function “balance
calculation” is activated (possible only for demand or energy increment),
then the difference between the positive and negative total registers is calculated at the end of the registration period and only the result is stored in
the relevant register. This value is then multiplied with the time factor (TF =
60/registration period length), which results in the demand value. At the beginning of each new registration period, the energy increment register (and
therefore also the demand register) will be set to 0.
Example:
Without balance
Demand

Result
With balance calcula-
tion
Export (+) 100 kW 100 kW 98 kW
Import (-) 2 kW 2 kW 0 kW

Page 24
3.5.4 Pulse outputs
The individual energy totals can be weighted with a separate divisor (defined in kWh/impulse) and forwarded to pulse outputs. Similar to the pulse
inputs, the duration of pulse length and pulse interval can be programmed
in the range from 10ms to 1000ms in steps of 10ms. A pulse output can
buffer up to 255 pulses. As soon as this value is exceeded, the unit sets the
correlated error bit in the unit status. This error bit can only be reset manually by the user. It is possible to link an output (Out1 to Out4) on a software
level to a particular totalling unit. When this link for a pulse output is modified, the pulse buffer of that output is cleared.
Please note that when the function „Differential Total calculation“ is activated (Hysteresis > 0), the relation between current demand and correlated
pulses at the output can temporarily run out of synchronization because of
buffered pulses.
3.5.5 Apparent demand and cos(
The DLX can calculate the apparent demand and the demand factor cos(ϕ)
of any input and total registers. One register each can be defined to hold
the active or reactive demand, respectively:
= ( cos )
ϕ
Up to two calculations of apparent demand and cos(ϕ) are possible. The
results are available on the display and can be stored in the periodic buffer
(load profile memory). For the cos(ϕ) the display (and the stored value) will
always contain the first three decimals.

3.5.6 Maximum demand calculation
At the end of each registration period, the unit compares the current demand value with the highest value registered so far. If the new value is
higher, then it will be stored together with date and time, separate for each
rate. This calculation only takes place for registration period Tm1. Current
maximum demand values and register contents can be retrieved via remote
data retrieval (currently only possible with SCTM protocol). Starting from
version 1.04.00, a maximum demand is also calculated without regard to
rates (in addition to the rate related values, and considering all days from
00:00 to 24:00).
3.5.7 Maximum demand reset
With a maximum demand reset the values for maximum demand of registration period Tm1 and the current energy register values are transferred
into the periodical buffer and then set to zero, to enable a new maximum
demand calculation. In addition, the values of the cumulative energy registers will be stored.
The reset can be activated in three ways:
1. Via control input RSTX. The unit will execute the reset approx. 200ms after the
change of the voltage level at RSTX.
2. Via internal clock automatically once per day, week, month or year. The time
can be selected without limitation.
3. Manually via the keypad (password protected).
All three methods can be enabled or disabled separately by means of set-
ting the relevant parameters. Only one reset is allowed for each registration
period Tm1. After a reset the next reset can be suppressed for a maximum
of 99 registration periods Tm1 (so called reset blockage).
3.5.8 Periodical buffer (Billing data)
Upon each reset, the DLX unit stores the maximum demand values, the
energy increment since the last reset (from the current energy registers)
and the value of the cumulative energy registers at the time of the last
completed registration period Tm1. These values are available on the display of the unit. The DLX will store at least the values of the last 20 resets.
Using remote data retrieval (currently only available for SCTM protocol),
maximum demand values and register readings for the last 9 reset actions
can be retrieved.
25
Page 26
3.5.9 Pulse barrier
With pulse barrier enabled all pulses arriving in a time window around the
end of registration period are buffered. These are forwarded in the next registration period, synchronizing all following devices. This is done to accomplish identical figures at main and control measurement.
Note: This can cause pulses appear as packets at pulse outputs and summation
registers.
Features:
•
individually configurable for every input
•
time range: ±9.9 s around end of registration period
•
settable in steps of 100 ms
3.5.10 Instantaneous value
For special calculation (e.g. fill level, fluid level, temperature) at the end of
registration period it is possible to activate the measuring for the last minute
in every registration period. This function can be activated only for pulses
and for registration period MP1/Tm1 (Buffer 1).
3.6 Time basis
The registration and calculation of demand values has to happen in a defined time frame. In order to calculate the correct tariff-related values, the
internal real time clock must be programmed to the valid official time (e.g.
CET = Central European Time or CEST = Central European Summer
Time).
3.6.1 Setting the real time clock
The integrated real time clock is buffered by a “GoldCap” capacitor, which
provides power for a minimum of 7 days in the event of a power failure.
Should the power failure last longer than the capacity of the “GoldCap“,
then the clock (the system time) will be set 59 minutes and 10 seconds after the date and time of the last stored value of the main registration period
Tm1 once the power supply returns.
The time can be set via the keypad, via the service interface or by means of
the SCTM message in the case of remote data retrieval (if this feature was
enabled during the setting of parameters). Please note that if summertime
switching is activated, the clock cannot be set or synchronized during the
time period of the “double” hour, due to the ambiguity of that period. During
this period the unit will ignore the command. In order to not affect time
management, the clock should not be set via more than one interface at the
same time.
26
Page 27
3.6.2 Automatic summertime switching
The DLX unit can perform automatic summertime switching if so desired.
The switching times (month weekday, hour) can be programmed (set) in
advance into a table.
Example:
Start of summertime:
Start of wintertime:
Please note that when using the table, both times must be programmed as
standard time (CET = wintertime), i.e. if the reverse switching from summer
to winter shall take place at 03:00 summertime, the value must be set as
02:00 in DLXPARA. After a unit reset, summertime switching is activated
(factory setting).
3.6.3 Synchronization
The internal real time clock can be synchronized to the closest full minute
via a freely programmable SYN control input (any of Ctl1 to Ctl7). Currently
two methods of synchronization are available:
•
Via external contact (e.g. external radio clock)
•
Via DCF77 receiver module (type AWS0) from the company Meinberg
(Germany)
In both cases the unit is synchronized to a full minute (seconds = 0). The
permitted synchronization window depends on a setting in DLXPARA:
last Sunday in March, switch from 2:00 to 3:00
last Sunday in October, switch from 3:00 to 2:00
•
SYN window = 0:
Synchronization in a window of ±30 seconds around each full minute; synchronization is always possible
•
SYN window > 0:
Synchronization in a window of ±x seconds (max. 29 seconds) around the
end of registration period Tm1, any attempt to synchronize outside of the
permitted time window results in the generation (and storage) of an error
event.
Inside synchronization window an alarm-free window can be defined. When
the DLX is synchronized out of the alarm-free window (but inside the synchronization window) a warning is generated (alert number: 07/02).
Example:
SYN window:
Alarm free:
Registration period:
→
Synchronization only permitted in a window of ±10 seconds around
each full 15 minutes (where minutes = 0 or 15 or 30 or 45).

The DLX cannot be synchronized while the parameterization pass-
word is active !
27
Page 28
3.6.4 Registration period
The registration period is the period of time used to calculate demand values (and energy increment values). At the end of a registration period, the
current value of the maximum demand registers will be stored. Subsequently the maximum demand registers will be set to zero. Two independent registration periods can be defined:
•
Registration period Tm1:
"Billing registration period" programmable in steps of 1, 2, 3, 4, 5, 6, 10, 12,
15, 20, 30 and 60 minutes.
•
Registration period Tm2:
programmable in steps of 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 minutes
as well as 2, 3, 6, 12 and 24 hours; if not required, this registration period
can be disabled;
registration period Tm2 can be programmed to the same value as Tm1.
Calculation of maximum demand values and billing data (see page 25) only
takes place for registration period Tm1.
28
Page 29
3.7 Rate dependent processing
The DLX can process up to 4 energy and maximum demand rates. Please
note that there is a differentiation between „number of rates“ (programmable) and “rate control” (settable).
With “rate control” one can select the method of switching between different
rates. There are two alternatives:
1. The rate is determined by control inputs TR1, TR2, TR3 and TR4 (external
rate control).
2. The rate is determined by the internal rate calendar.
The "number of rates" determines how many different rates the unit will dif-
ferentiate and use. If the unit is programmed to use less than 4 rates, then
the limit used is the highest programmed rate. If, for example the number of
energy rates is programmed to 2, then the energy registration will only allow rates 1 and 2, even if the rate calendar stipulates rate 4. In this case
rate 2 would be used instead of rate 4.
Example:
Number of rates:
AT1 (theoretical)
AT2 (theoretical)
AT3 (theoretical)
AT4 (theoretical)
3.7.1 Rate control
The currently active rate can be determined either via the rate control inputs (e.g. radio clock, or ripple control receiver) or via the internal rate calendar. Both are queried all the time:
•
AT:
Changes have an immediate effect on the energy rate.
•
MT:
The current maximum demand rate is always determined 5 seconds
before the end of the current registration period and is then valid for this
registration period (only one demand rate is possible per registration period.

3.7.2 Rate calendar
The device has a rate calendar with a table for up to 100 public holidays.
The internal rates can be transmitted to external devices using the control
outputs (Out1 to Out4 or Rel1 and Rel2), e.g. to control other devices.
The rate program (settable) is stored in the form of an internal rate calendar, which is hierarchically structured in three levels. The highest level defines the seasons, the second level defines the weekly programs and the
lowest level defines the daily rate tables with the switching times for rates.
The definition of seasons allows up to six periods within one year (e.g.
summertime or wintertime) that can have different rate structures.
Example:
(default value in DLXPARA: 1 ---)
Season 1:
Season 2:
Each active season requires the definition of a weekly program, which assigns the relevant daily rate switching tables (1..15) to weekdays. This can
be shown in a table as follows:
Season Weekdays
Mo Tu-Th Fr Sa Su PH1 PH2 PH3
1 1 1 1 1 1 1 1 1
2 2 2 2 2 2 2 2 2
3
4
5
6
In the table, weekdays are abbreviated as follows:
Mo = Monday Tu-Th = Tuesday / Wednesday / Thursday
Fr = Friday Sa = Saturday Su = Sunday
PH1, 2, 3 = Public Holiday Type 1, 2, 3
from 01.03 00:00 to 01.10 00:00
from 01.10 00:00 to 01.03 00:00
The three types of public holidays (PH1, 2 or 3) allow you to define single
weekdays to have special rates that are set in a separate definition table.
These public holidays have higher priority than normal weekdays and allow
one to consider holidays such as Easter, Christmas or other country specific holidays.
The sample entries in the above shown weekly program mean that in season 1 the daily rate table 1 shall be used all the time and in season 2 the
daily rate table 2 is valid. Of course, different daily rate tables can be used
for each weekday within a season, however only a maximum of 15 daily
rate tables are available.
These daily rate tables define which energy rate and maximum demand
rate shall be active at what time and also which control outputs must be
used to signal the rates to subsequent external devices. Each daily rate table can have up to 16 rate switching times.

3.7.3 Rate control inputs
The rate control inputs TR1 to TR4 determine (if desired and if present in
the customer specific hardware configuration) the currently active energy
rate and maximum demand rate. The usage of inputs and the correlation of
input states to rates can be programmed freely (settable).
The factory default settings use TR1 to switch between two energy and
demand rates.

The state of deactivated control inputs (in our example: TR2, TR3 and
TR4) has no influence on the rate control (no matter whether the state
is 0 = open or 1 = closed).
If other combinations are desired, they can be programmed (see user manual of DLXPARA).
Example: rate control for 4 energy rates and 2 demand rates, controlled by TR1, TR2
and TR3.

3.8 Storage of measurements
3.8.1 Internal memory
All data that needs to be retained during a power failure, is stored in internal memory (Flash technology, non volatile without backup battery, size of
internal memory : 1MByte). These are all device parameters, registration
period data (load profile data), spontaneous events and resets (billing
data).
Each type of data uses a separate area of memory, which is administered
separately. Memory is organized as a circular buffer, i.e. once a particular
storage area is full, the “oldest” information will be overwritten.
The registration period memory area can alternatively contain demand values, energy increments or cumulative counter values, positive and negative
totals, apparent energy and cos(ϕ).
3.8.1.1 Unit restart (Loading of factory default settings)
After a unit restart (message in the display (“Parameter Reset”) the complete internal memory (device parameters, spontaneous events, resets and
registration period data) is erased and the standard parameters will be
loaded (see menu item “Factory settings”, page 95). A unit restart can be
executed in the following ways:
•
Via the keypad: menu item „SET PARAMETERS – Factory settings”. This
is password protected.
•
Via the programming software DLXPARA (using the service interface. This
is password protected.
•
Via hardware reset: switch off the unit and place a jumper onto the pins la-
belled “Test” (located on the CPU board under the display), then power up
the unit and wait until the display shows “Parameter Reset”, then remove
the jumper. This is protected by seals.
If parameters defining the buffer usage (number of counters, totals,
digits, measurement types or storage allocation) are altered, the registration period buffer and the reset memory are erased automatically.
3.8.1.2 Unit warm start
The DLX unit performs a warm start (message in the display: “System
warm start”) under the following conditions:
•
On return of power supply after a power failure
•
When placing the “Reset” jumper on the CPU board.
Data device parameters and data remain intact. No data will be stored for
registration periods during which the power supply was absent. An event
will be stored in the spontaneous event buffer for a unit warm start.
33
Page 34
3.8.1.3 Unit cold start
The DLX unit performs a cold start (message in the display: “System cold
start” under the same conditions as above, if the internal RAM memory
could not be buffered by the GoldCap (minimum of 7 days without power
supply voltage). In this case all device parameters and the device internal
system time need to be reconfigured. All data in the registration period
buffer is retained, and the system time is set to 59 minutes and 10 seconds
after the timestamp of the last stored entry in the main registration period
buffer. An event will be stored in the spontaneous event buffer.
3.8.1.4 Erase memory
All internal memory (spontaneous events, resets and registration period
data) can be erased using the menu item „SET PARAMETERS – Erase
memory“. The device parameters are retained. An event is stored in the
spontaneous event buffer.
3.8.2 Security mechanisms for data storage
All data is secured in a number of ways: when data is stored, each byte
written is checked by an additional read cycle; for each block of data a
checksum is stored which is checked for correctness when the block is
read. Data is only used and forwarded when the checksums match.
3.8.3 Block diagram of internal memory
Figure 9, Block diagram of internal memory
The internal registration period memory can be divided into two areas for
registration periods Tm1 and Tm2 (if active), using DLXPARA. Each area
can contain counter readings, energy increments or demand values with 4,
6 or 8 digits.
Data stored in internal memory can additionally be stored on a PC-Card
(backup memory, see page 90).

Due to the composition of FLASH memory devices a minimum of sec-
tors of 65536 Bytes each is allocated to each area (the exception being the device parameters with 1 sector). When registration period
Tm2 is disabled, no sectors will be reserved for the second periodic
buffer (using 100% for Tm1). The spare sector used for internal sector
management is in this case used for the Tm1 buffer (thus “memory
share for Tm1” is set to 10).

3.8.5 Capacity of backup memory (PC-Card)
Due to technological and administrational reasons the whole memory of a
PC-Card is divided into sectors. Data is always written or erased by complete sectors.
Depending on the card type the following sector sizes are available:
•
SRAM cards: 256Byte
•
FLASH cards: 128kByte (:=131072Byte)
The memory is divided into the following areas:
Memory area
Administration information: Number of bytes (Sectors)
Spontaneous events: Number of bytes (Sectors)
Number bytes per event
Number of events
Reset buffer:
(cumulative counters,
without rates)
Registration period Tm1: Number of days
Registration period Tm2: Number of days
Intermediate buffer: Number of Bytes (Sectors)
The number of stored entries per memory area varies depending on the
level of usage in individual sectors.
DLXPARA can determine the required memory capacity of a PC-Card and
this information can retrieved from the unit via SCTM protocol (see appendix A: table addresses 700-80 and 700-81).
Checksums are created for each block of data to protect against corruption.
The checksum is the arithmetic sum total of a block of data and it uses one
byte of memory. The amounts carried over from the summation are discarded.

Each block of data can vary in length. For buffers one block of data is
equivalent to one buffer entry. Administration information is also divided
into blocks of data.

3.9 Control inputs
The DLX unit can have up to 7 control inputs (Ctl1..Ctl7). These inputs are
by default of the S0 type (also called IES), but optionally they are available
in wipe technology (IEW). Control inputs are programmed and activated by
the software application DLXPARA. The following functions are available:
•
SYN- input:
•
RSTX- input:
•
ANZ- input:
•
TR1 to TR4:
•
Log1 to Log4:
Synchronization of the internal real time clock via external
transmitters or external DCF77 receiver (see page 86)
External maximum demand reset
External control for scrolling of the display
Rate control via external transmitters (e.g. ripple control
receivers)
Logic inputs that allow connection of the DLX with signal
outputs of external devices. With these inputs the user
can create and log events that are relevant to the processing of meter readings (e.g. defective transformers or
external fault messages). The logic inputs are scanned
every 10 seconds (second 5, 15, 25, 35, 45, 55). Incoming signals are stored in the spontaneous events buffer
together with date and time. They can additionally be
stored (this needs to be enabled by DLXPARA) in the device status data of the registration period area (L-bit, see
appendix A).
Control inputs are subject to a signal detection in software similar to the
one used for pulse inputs, i.e. pulses that fall short of a minimum length are
not considered. For control inputs the minimum pulse length and the minimum pulse interval is set to 30ms.
37

3.10 Outputs
The DLX data logger (remote metering device) can have up to 6 freely programmable outputs, which are available in wipe technology (Out1 to Out4,
type IAW) and as mechanical relays (Rel1 and Rel2). Corresponding light
emitting diodes (LED) in the display show the state of each output (output
closed or active: LED is lit). The following functions are possible:

3.11 Communication
The Data logger can communicate (for programming and for data retrieval)
via three serial interfaces:
•
Service interface: RS232
•
Com1 (Data interface): RS232, RS485, 20mA/CS, M-Bus or fiber-optic
•
Com2 (Modem): PSTN, ISDN, LAN/Ethernet-Connection
optional: second data interface
Programming is only by service interface possible.
An exact description of all interfaces is contained in section “8 Interfaces”
and section “9 Modem/Com2 (Optional)”
The DLX currently supports three different protocols::
•
SCTM
•
IEC 60870-5-102
•
Modbus RTU (alternative to SCTM / IEC 60870-5-102)

4.1 Sealing arrangements
4.1.1 Housing for panel mounting
The keypad can be sealed by two sealing screws in the upper left and
lower right corner of the keypad. The sealing wire needs to be fed through
the whole in the enclosure and through the sealing screw and a seal needs
to be attached to the wire.
Sealing of the PC-Card cover or the terminal cover is done by means of a
sealing screw and the splicing plate of the PC-Card cover or the terminal
cover. After placing and fixing the cover the sealing screw is fixed through
the whole in the splicing plate and then sealing wire needs to be fed
through the holes in both the splicing plate and the sealing screw and finally
a seal is attached to the wire. Alternatively the PC-Card cover can also be
secured with a padlock (according to the VDEW requirement definition for
electronic watt-hour meters, Version 2.0).

5.4.7 Input and output modules
Input and output modules convert the pulse types and voltage levels of
commonly used signals in metering technology into TTL signals used by
the micro controller (and vice versa). At the same time these signals are
galvanically isolated from the process.
These types of input modules are available:
IES Pulse input S0
S0 inputs are active inputs, i.e. they not only supply the transmitter with a
signal voltage, but also with an auxiliary voltage. S0 transmitters can contain their own electronic circuitry without the need to have their own power
supply. The relevant current and voltage limits are defined in DIN 43864.
S0 inputs are capable to deliver 10mA to an 800Ω transmitter (to supply the
transmitter) and they still recognize a maximum current flow of 2.2mA as an
“Off” signal. They are limited to supplying a maximum voltage of 27V.
Therefore S0 inputs are well suited for simple potential free contacts and
passive transmitters using optical couplers or transistors and they are frequently used for control signals (synchronization, rate control, resets etc.)
IEW Pulse inputs of type „wipe“
These inputs are passive inputs, i.e. they are supplied by the transmitter. A
metering pulse is transmitted directly as a voltage signal. In practice many different voltages and currents are used.
The input modules used can be operated with DC or AC signals from 24 to
265V. The maximum pulse frequency is at 10Hz, current consumption is less
than 10mA. Indefinite pulses (permanent contact) are permitted. This makes
IEW modules basically suitable for control signals.
IED Pulse inputs of type „bi-current / bi-polar“
“Bi-current“ inputs are passive inputs, i.e. they are supplied by the pulse
transmitter. As such they are not linked to any voltage. „Bi-current“ pulses
are DC voltage pulses of alternating polarity. A pulse is recognized by the
transgression of the 0V level. Instead of DC voltage pulses a permanent
DC voltage that changes its polarity for each pulse, can also be used. The
standard voltage is 24V, but it can vary from 18V to 60V. Our bi-current
pulse inputs have an input current of less than 2mA at 24V. As each input
pulse is represented by a change of polarity of the input voltage, our IED
modules internally produce a complete pulse of typically 20msec duration
for each change of polarity. This needs to be taken into consideration for
the maximum pulse frequency (max. 20Hz). If desired, IED modules with
90msec are available, which can be used up to 6Hz pulse frequency. Bicurrent transmission lines are highly immune to disturbances and should be
used for long distance transmissions. Depending on the environment
49
Page 50
(neighboring lines, transmission distance) a shielded cable of sufficient diameter should be used.
As each pulse is represented by a change of polarity, the signal con-
dition must be deactivated in "DLXPARA" (minimal high phase =
10msec).
Analogue Signal current input (analogue input 0..20mA or 4..20mA)
A continuous signal current flow is applied to the signal current inputs (e.g.
0..20mA or 4..20mA). This current is proportional to the actual demand.
The method of calculation can use pulses or digital values to transmit the
data to the DLX (Main-)CPU.
Pulse: For firmware version up to 1.05.06: the signal current input (analogue input)
measures power in order to establish energy consumption. The power is
measured over short intervals, multiplied by the time and the result is summated. This sum is equivalent to the energy consumed. If the sum exceeds
a fixed limit value "W", a 25msec internal output pulse is triggered and "W"
is subtracted from the sum. "W" is designated the pulse weighting and is
set such that at maximum demand a pulse frequency of 20Hz (pulse length:
25msec) is reached. The demand is measured via an external transducer
that converts the measured demand to an injected current (selectable
ranges: 0 to 20mA or 4 to 20mA).
Maximum current:
0..20mA (:=20mA) 72000 pulses per hour (:=3600sec × 20)
4..20mA (:=16mA) 57600 pulses per hour (:=3600sec × 16)
The signal condition must be deactivated in "DLXPARA" (minimal
high phase = 10msec).
Digital: For firmware version from 1.06.00 and up: the average value (50 scans per
second) will be send every second to the DLX-CPU.
The following types are used as output modules:
IAW el. Pulse output type „wipe“ (solid state, Out1 to Out4)
Electronic outputs of type wipe behave the same as relay contacts, i.e. they
can carry a burden of up to 250V and 100mA for AC or DC. They combine
wear free switching with high switching frequency and are therefore ideal
for high pulse frequencies. They can drive S0 inputs directly.
Restriction: Wipe outputs are always of type “normally open”.
IAW me. Pulse output type „wipe“ (relay contacts, Rel1 and Rel2)
Mechanical relays are currently the only practical solution for the implementation of transmission lines without auxiliary voltage. Similarly, only mechanical components are available for outputs with change-over contacts
(idle contact and active contact). Due to a life span of approx. 5 x 105 they
are not suitable for the transmission of pulses.
Note: Electronic outputs (IAW el.) are generally less problematic.

7.5 Scroll list
Figure 28, Flow diagram for the scroll list
Selecting the scroll list
(if programmed)
The first entry of the scroll list is always shown in line 3 and 4 of the standard display.
Press the key to show the second entry of the scroll list in the dis-
play.
Scrolling the list
There are three ways to scroll through the list:
1. Manual scrolling by pressing the key:
Each press on the key shows the next entry of the scroll list in the display. When there are no further entries in the list, the display returns to the first
entry.
2. Automatic scrolling of the list based on a time delay:
In order to activate automatic scrolling of the scroll list, the delay (in seconds)
determining the time period for which each entry is displayed, must be stipulated in the programming software. Once this time is set, the display will scroll
automatically (from the time the parameters are programmed into the unit).
Each press of the key interrupts (and resets) the time delay and moves
the display to the next entry. After the delay time has elapsed, automatic scrolling will be resumed.
3. Scrolling by means of the ANZ control input:
Each activation of the ANZ control input activates the next entry of the scroll list
in the display. Once the list is exhausted, the display returns to the first entry.
Other key functions:
if no scroll list was programmed, pressing the key has no function
(other than activating the display illumination).
- and these keys have their usual function during the display of the scroll list (i.e.
the
key displays the Select Language menu and the key enters the
main menu).
59
Page 60
Content of the scroll list
Programming of the scroll list can only be done with the programming software DLXPARA. An entry into the scroll list consists of the scroll list entry
text, the related value and a physical unit:
•
Line 3 shows the freely programmable text (max. 20 characters)
•
Line 4 shows the related value (selected by address) and the program-
mable unit (5 characters)

decreases the selected parameter to the next lower possible value.
One digit of the selected parameter blinks in the display. On each change
of the parameters the measurement display will be updated.
If no value is available for the selected parameters, then automatically the
next valid entry from the registration period buffer will be displayed. This is
an easy method to request the oldest or newest load profile entry: modify
the input field for the year with the or the key until there are no further
changes of the display: the display now shows the oldest load profile entry
(after using the key) or the newest load profile entry (after using the
key). Invalid values or values incompatible with memory entries cannot be
requested.
When displaying energy or demand values from the load profile memory,
the unit always shows the total value (not rate related) together with the active energy and demand rate valid at the end of the registration period (you
cannot edit the rate).
When displaying billing data, the values are shown depending on the rate,
which can be selected. Each entry can only be selected by the secondary
reset index (0..99), the primary reset index (1..12, settable) will be displayed automatically.
The unit differentiates between inputs (I01 to I16), totals (S01+ to S04-),

Modem interface “Com2” for remote data retrieval (optional); device can
also be equipped with a second data interface “Com2” instead of the modem.
8.1.1 Automatic protocol recognition
The DLX unit automatically recognizes the retrieval protocol (currently
SCTM, IEC60870-5-102 or the programming software DLXPARA). On both
direct interfaces (service interface and data interface/Com1) the first query
telegram will be lost in the case of a protocol change (the modem interface
can change the protocol without losing a telegram). Therefore DLXPARA
can be used to define the default protocol for the data interface (the default
protocol for the service interface is always the IE60870-5-102 protocol).
The DLX unit will switch to the default protocol after each programming activity and after 5 minutes with no communication on the relevant interface.
Starting from version 1.05.00 it is possible to activate the protocol Modbus
RTU (instead of SCTM / IEC 60870-5-102 for the interfaces Com1 and
Com2 only).
Due to safety reasons the programming software can only communi-
cate with the service interface.
Remote parametering is not possible!

8.2 Service interface
The service interface is used to program the DLX unit and to retrieve data
with a fixed baud rate (9600 baud). It is implemented as a 25 pin SUB-D
connector (female) according to ISO2110, the pin allocation is according to
V.24/RS232C/DIN 66020.
Programming of the DLX is done using the programming software
DLXPARA. Please read the user manual of the programming software
DLXPARA for instructions on programming.

8.3 Data interface Com1 and Com2
The optional data interface can be used for data retrieval on site with data
retrieval software (e.g. SIGLON) or to connect to an external modem. The
baud rate can be set with DLXPARA to a value between 300 and 9600
baud. It is implemented as a 25 pin SUB-D connector (female) according to
ISO2110, the pin allocation is according to V.24/RS232C/DIN 66020.
Alternatively a 25 pin SUB-D male connector, a bus interface (20mA/CS,
M-Bus or RS485) or a FO connector (fiber-optic transmission connection)
can be used.
8.3.1 Pin allocation RS232 SUB-D (female)
The standard pin allocation of the data interface is identical with the service
interface (see page 78). For the connection between the DLX and a PC, a
modem cable is required. For the connection between a DLX and an external modem a so-called null modem cable (crossed wires) is required.
8.3.2 Pin allocation RS232 SUB-D (male)
For the connection between the DLX and a PC, a null modem cable
(crossed wires) is required. For the connection between a DLX and an external modem a modem cable is required (1 to 1).

The DLX can be optionally equipped with a receiver for the signals transmitted by the long wave transmitter DCF77 (time codes). The type used
must the DCF77 aerial/receiver unit AWS0 from the company “Meinberg
Funkuhren“ (Germany). The receiver module requires a +12VDC auxiliary
voltage and it can be connected to a S0 control input of the DLX.
Figure 47, DCF77 receiver module AWS0
10.1 Function
Synchronization of the time to full minutes (seconds = 0), no setting of the
time! Prior to using the unit, the time must have been set to within 30 seconds via the main menu item „Maintenance – Set time“ or by means of the
programming software DLXPARA.
Note: Synchronisation one time per measuring period only.
10.2 Setting the parameters for the receiver module
Activate the item “Synchronization via external radio clock” in the menu
item “Parameters – Time” in DLXPARA and allocate the used control input
in the menu item “Control Inputs” to the “SYN” function.
You must not allocate more than one control input to the SYN func-
tion!
The display of the data logger will show the corresponding symbol when
the receiver module is active: " ".

10.3 Commissioning
10.3.1 Connection
Coaxial cable:
1. Shield to SYN- (Ctl–) terminal
2. Wire to SYN+ (Ctl+) terminal
10.3.2 Alignment of the receiver module
The receiver module must be aligned to show its long side to the transmitter, which is located in Frankfurt/Main in central Germany.
Minimum distances:
•
min. 1m to computers and monitors
•
min. 30cm to steel girders, metal plates and other metallic devices.
Checking the alignment
The modulation LED in the aerial enclosure of the AWS0 needs to blink
once per second. The corresponding LED on the DLX (for the control input
SYN) needs to blink in the same rhythm. Rotate the receiver module slowly
and select an alignment roughly at the center of the area with good signal
reception. If you have good reception , the DLX display will show a static
symbol " " latest after 3 minutes. A blinking symbol " " indicates disrupted
radio clock signal reception.

11 PC-Card
11.1 Permitted PC-Card's
•
Standard: JEIDA/PCMCIA
•
Type: SRAM battery backed
Flash Memory-Card (AMD, D Series)
•
Capacity: up to 4MByte
11.2 Treatment advice for PC-Cards
Noncompliance with the following advice can lead to destruction of
the PC-Card.
•
Do not bend or fold the PC-Card or subject it to similar conditions.
•
Do not drop the PC-Card.
•
Always keep the PC-Card dry and free of dust.
•
Do not expose the PC-Card to high temperature or high humidity.
•
To avoid static charges, always store the PC-Card in its original packing
when it is not in use.
•
Do not touch the connections of the PC-Card.
•
Never use force when inserting a PC-Card. Only insert the card into slots
designed for them.
•
Do not remove the PC-Card from the unit until it has been deactivated.
90
Page 91
11.3 Inserting a PC-Card
Figure 48, Inserting a PC-Card
Please ensure that you always insert the side of the PC-Card with the connector into the PC-Card slot. Also ensure that the guiding grooves on the
card match those of the slot, as shown in the above picture. The PC-Card
is guided in the slot by two guide rails that prevent the card from twisting.
Slide the card into the slot and press carefully until the PC-Card reaches
the final position (PC-Card and ejection button are aligned, see arrow ).
After inserting the PC-Card it needs to be activated by the DLX in or-
der to use it for storage purposes.
The display will show the symbol " " in position 18 of line 1 after the card
has been inserted and successfully activated by the DLX unit.
If the card is not activated by the unit, the symbol will blink and the display
will show the message “PC Card is not activated!”.
91
Page 92
11.4 Activating a PC-Card
Use the menu item „Activate PC-Card“ (see page 73) to activate a PCCard. After activation the symbol " " will appear in the first line of the LC
display.
Activation includes the following actions:
1. The DLX determines type and capacity of the PC-Card.
2. The DLX checks whether the capacity of the card is sufficient for the programmed number of counters and days for the registration period buffer.
3. Once the PC-Card has been found to be suitable, it will be formatted to ensure
that recording always takes place on an empty PC-Card.
4. Afterwards the administration information will be stored on the PC-Card.
11.5 Deactivating a PC-Card
A PC-Card needs to be deactivated before it may be removed from the
DLX. The deactivation updates the administration information on the PCCard. Use the menu item “Deactivate PC-Card” (see page 74) to deactivate
a PC-Card. Once this is done, the symbol " " disappears from the first line
of the LC display.
11.6 Removing a PC-Card
Press the eject button (see Figure 48, Inserting a PC-Card) on the right
hand side of the PC-Card to remove the card.
Only after deactivation via the keypad (see menu item "Deactivate PC-
Card" page 74) the PC-Card may be removed from the PC-Card slot.
If the PC-Card is removed from the DLX without prior deactivation, it
cannot be read by other processing software! The " " symbol starts to
blink and a corresponding alarm message will be created.
92
Page 93
11.7 Data storage on a PC-Card
The following information will always automatically be stored on a PC-Card
(independent from the program parameters of the unit):
•
Spontaneous events: the PC-Card will always contain at least the last 100
events.
•
Billing data: the PC-Card will always contain at least cumulative
rate less counter values of the last 4 reset instances.
By default (if nothing else was programmed with DLXPARA) the demand
values of counters 1 through to 16 for registration period Tm1 will be stored
for the last 35 days. The PC-Card will be used as a circular buffer, i.e. once
the buffer is full, the newest incoming value overwrites the oldest value.
You can use the programming software to activate storage of data for registration period Tm2. In addition, you can select which values shall be stored
and what the storage depth in days will be. For more information see page
36.
The PC-Card will only ever store values that have been registered or
calculated after the time when the card was insert and activated.
93
Page 94
12 Registration of Measurements
The device starts to register measurements immediately after the power
supply is switched on. This data will be stored together with timestamps
and device status in the registration period buffer according to the selected
parameters (the factory settings will be used when the unit starts for the
first time).
Setting the time during measurement
If the time is set backwards during measurement, all registration period
buffer entries with a timestamp after the newly set time are marked as invalid and they are then no longer accessible via data retrieval. If the time is
set forwards, all registration periods in the skipped period are treated like
entries during „power down“ condition and are displayed as „--------„.
Memory overflow:
Once the memory capacity of the registration period storage has been exhausted, the oldest entries will be automatically overwritten (due to the
storage technology used this affects at least one sector = 64kByte in the
buffer).
Power failures:
Should a power failure include the end of a registration period, then all registered measurements up that point in time will be stored at the end of the
first incomplete registration period. This period will then be marked as incomplete.
Registration periods without power:
Should the device not have been supplied with power for one or more complete registration periods, then these are called „power down“. These registration periods do not use memory. If values are requested from these
periods for display purposes, they are shown as “--------“.
Storage during programming:
The device continues to register measurements during the period of programming without interruption. Once programming is terminated, it checks
which parameters have been modified. If the storage allocation or the registration period length was altered, all of the registration period storage area
will be cleared.

13.2 Light Emitting Diodes (LED’s)
13.2.1 LED AL1 Warning
The LED „AL1“ blinks after a fault of class „W“ (warning) has occurred. After manually clearing of the error message the LED „AL1“ goes off. Exceptions to this rule are the warnings 03/01, 03/02, 06/xx and 8E/xx where the
LED “AL1” will be automatically cleared after the end of the registration period (Tm1/MP1).
13.2.2 LED AL2 Device fault
The LED „AL2“ blinks after a fault of class „F“ (device fault) has occurred.
The critical faults that can only be removed by the manufacturer.
13.3 Fault indication output
Apart from the optical display you have the possibility to forward error messages to the outside via the freely programmable outputs (mech. relays or
solid state outputs). The assignment of faults to outputs is done in
DLXPARA. Faults of class „W“ (warnings) correspond to alarm 1 (AL1) and
faults of class „F“ (device faults) correspond to alarm 2 (AL2). The fault indications are active until the corresponding fault has been cleared. Exceptions to this rule are the warnings „03/01 – power failure“, „03/02 – power
dip“, „06/xx – Data memory: data erased” and “8E/xx – Energy register
overflow”, where the error will be automatically cleared and the fault indication output don’t be activated. These messages are stored in the alarm
buffer and in the spontaneous event buffer. During the alarms and power
failures the relay outputs return to their default (idle) state and the solid
state outputs are inactive.
13.4 Message buffers
All internal messages are stored in two different message buffers and device status:
•
Alarm buffer
occurred and that are not cleared are stored permanently in the internal
alarm buffer. The contents of this buffer can be shown via the „Main menu
- Display alarms“. The buffer can be cleared via “Main menu – Erase
alarms“.
•
Spontaneous event buffer
(at least the last 780) are stored permanently in the internal buffer for
spontaneous events. The contents of this buffer can be displayed via „Main
menu – Info – Spontaneous events“.
•
Device status:
for each completed registration period (see appendix A, SCTM Protocol).
Warnings 03/02 (power dip) don’t stored in the device status (from version
1.04.03 up).
: in addition to the LED display all alarms (faults) that have
All warnings and device faults are stored in device status
