measured values are transferred to the work-
ing memory of the device depending on the
programmable memory cycle and memory
value (current value, average value, maximum
value, minimum value, or minimum/maximum
values). The paperless recorder stores the
data according to group; one input can be as-
signed to multiple groups (max. 4).
Working memory (SRAM)
The data stored in the SRAM is copied to the
internal memory in 20-kByte blocks at regular
intervals.
Internal memory (flash)
Whenever a memory block in the working
memory is full, it is copied to the internal mem-
ory. The internal memory has a maximum ca-
pacity of 1 GB. Each write operation is
monitored to ensure that any data storage er-
rors are detected immediately.
The device monitors the capacity of the inter-
nal memory and, if the remaining capacity falls
below the configured minimum, a memory
alarm signal is triggered. This can, for exam-
ple, control the alarm relay.
The data is written to the memory as a ring
buffer, which means that when the memory is
full, the oldest data is automatically overwrit-
ten with new data.
To show the history in the paperless recorder,
data from the internal memory can be dis-
played (history memory: 8 MByte).
Data transfer to PC
Data can be transferred from the paperless re-
corder to a PC via a USB flash drive or via one
of the interfaces (USB device, Ethernet).
Data security
Data is stored in an encrypted format devel-
oped by JUMO. This ensures a high level of
data security.
The following applies if the paperless recorder
is disconnected from the voltage supply:
• Measurement data in the working memo-
ry and time are buffered by a lithium bat-
tery (operating life > 7 years).
• If the lithium battery is discharged, the
measurement data in the working memo-
ry and the time are lost. For the purposes
of a battery change, the data is buffered
for approximately 2 minutes by a storage
capacitor.
• Measurement and configuration data in
the internal memory are not lost.
Extra code 887 gives the device reliable ma-
nipulation detection. A digital device certificate
verifies that the recording data in the device
has not been manipulated – which also ap-
plies to the transfer into the data archive.
Recording time
The maximum recording time depends on a
number of factors, in particular on the set
memory cycle. The values specified in the ta-
ble (entries in the event list reduce the maxi-
mum recording time) apply when a group with
6 analog channels is activated in standard op-
eration and storage of average values (not the
minimum/maximum values).
Reports
For each channel in a group, reports can be
maintained over specified time periods (maxi-
mum, minimum, and average values). Config-
uration takes place for each group.
Batch report
The paperless recorder allows a batch report
to be created for one plant. The measurement
data, the beginning, end, and duration of the
batch can be displayed together with a batch
counter and freely definable texts on the pa-
perless recorder and in the PC Evaluation
Software PCA3000. A barcode scanner can
also be used to start and stop the batch and to
load batch texts.
Operating modes
The operating mode can be selected individu-
ally for each group. The memory cycle and
memory value can be separately configured
for each operating mode. Up to 4 groups can
be recorded with one memory cycle of 125 ms.
The operating modes have different priorities:
Event operation
Event operation is activated/deactivated by a
control signal (such as a digital input, group, or
collective alarm). The device is in event oper-
ation for as long as the control signal is active.
Event operation has the highest priority.
Memory cycle Max. recording
time
125 ms Approx. 42 days
1 s Approx. 8 months
5 s Approx. 41 months
10 s Approx. 82 months
60 s Approx. 493 months
Time operation
Time operation is active on a daily basis within
a programmable timeframe, providing event
operation is not active.
Standard operation
If the device is not in event or time operation,
standard operation is active.
Limit value monitoring
Up to 24 analog values can be monitored by
the configurable limit value monitoring func-
tion. In the event of deviation above or below
the limit value, an alarm signal is generated
that can be used for individual purposes (such
as switching the operating mode from stan-
dard to event operation).
The alarm delay can be used to hide short-
term deviations above or below the limit value
so that no alarm signal is issued. It is also pos-
sible to suppress the alarm signal by a digital
signal.
Limit value and switching differential can also
be changed as part of parameterization, pro-
vided the user has the rights to do this.
Counters/integrators
Six additional internal channels are available
as counters, integrators, operating time count-
ers, or to determine the total flow volume. Two
high-speed counters (up to 12.5 kHz) can be
implemented via the digital inputs/outputs 1
and 2 (option 3). These optional inputs are
also required for flow measurement, if the
pulses of a flow transmitter are to be evaluat-
ed.
The counters are controlled via digital signals
(counting pulses), whereas the integrators are
controlled via analog signals (value integrated
according to the selected time base). Operat-
ing time counters determine the timeframe
during which a digital signal is active.
The value of the counter/integrator is dis-
played in a separate window of the paperless
recorder in numerical format with a maximum
of 9 digits (in the event that this is exceeded,
the counter restarts with 0). Different recording
periods can be set. A minimum and maximum
alarm can be configured for each counter/inte-
grator.
Math and logic module
The math and logic module (each with 6 chan-
nels) is available as extra code.
The math function can be used to link various
analog and Boolean input variables using a
formula which can be defined freely in accor-
dance with mathematical rules (formula with a
maximum of 160 ASCII characters). The out-
