1 Introduction

1.2 Arrangement of the documentation

The documentation for this instrument consists of the following parts:
Operating Manual 59480
Interface Description 59482
This operating manual comes with the delivery. It is addressed to the equipment manufacturer and the user with appropriate technical expertise.
In addition to installation and electrical connection, it contains information on commissioning, operation and parameter setting on the instrument, as well as on the optional PC setup program and the optional evaluation program (PCA).
It provides information on the serial interface (RS232 and RS485), which can be supplied as an extra code. The interface description can be used to develop specific programs which can, for instance, read out current measurement data.

1.2.1 Structure of this operating manual

This manual is arranged in a way which permits the user to enter directly into operation and configuration of the instrument. Consequently, chapters dealing with items that normally arise only once are placed at the end of the manual. These include instrument description, type designation, installation and electrical connection.

depending on the display mode.
Example: Measurement (small meas.)
Selection and visual presentation of the channel line can be controlled through the parameter Parameterization ➔ Diagram view ➔ Channel represent. or by
using the key. With the help of the parameter Parameterization ➔ Diagram view ➔ Channel
indication ➔ Channel 1 — 6, it is possible to suppress the display of individual channels in the channel line. This is especially useful for scale or bar graph display, where more space is needed to show the diagram. The channels that have been suppressed in the display will nevertheless be recorded, and shown on the diagram.

2.3 Analog inputs

Internal analog inputs
The paperless recorder can be equipped with 3 or 6 analog inputs. When configuring the analog inputs (Chapter 4.2 “Table of configuration parameters”), these are designated as analog input 1 — 3 (1 — 6).

2.4 Digital signals (event traces)

Signal types In addition to the four binary inputs (extra code), digital signals generated by
the instrument itself can also be displayed in the six digital traces (event traces):

Outputs The digital signals can be used to operate three relays (extra code). The action
can be configured as a break (SPST-NC) or make (SPST-NO) contact (Configuration ➔ Outputs).
External texts External texts can be called up via four binary inputs or the logic channels. If a
binary input is closed or a logic channel makes a 0-1 transition, then the preconfigured text will be entered in the event list. Either a standard text or one of the 18 definable texts can be used. The instrument automatically supplements the texts in order to distinguish between the appearance and disappearance of the signal. The external texts are configured on the instrument, under Configuration ➔ Control functions.
v Chapter 3.5 “Event list”
Event operation The digital signals can be used to activate event operation. In event operation,
the measurements are stored with a storage cycle that is different from normal operation.

2.5 Counters / integrators / operating time counter

16
These are not electrical measurement inputs (hardware), but channels which are calculated by the paperless recorder (software).
2 Device description
Counters
Counter inputs Any of the digital signals can be used as input signals for the counters.
v Chapter 2.4 “Digital signals (event traces)” Example:
- binary inputs
- logic channels
-alarms
- memory alarms
- Modbus flag (signal via interface)
Counter frequency
Evaluation The count pulses can be evaluated (weighted). A down counter can be
30Hz max.
implemented by entering a negative weighting (e.g. weighting factor -1). Each count change can be documented with an entry in the event list. The
new count is attached to the message.
Integrators
Integrator inputs
Integrator time base
Evaluation You can also enter a weighting for the integrators.
Weighting example
Analog inputs 1 — 3 or 1 — 6 and math channels 1 — 6
sec, min, hr and day
- measurement of flow volume
- input signal of 0 — 20mA (corresponds to 0 — 500 liters/sec)
- time base 1sec
Minimum size of the input signal
- weighting 0.001 Result: display of the integration value (volume) in m³.
Entering a threshold value (amount of the threshold value) has the effect that integration takes place only when the value has been exceeded. No integration will occur on falling below this value. The advantage of integration with a threshold value larger than 0 is that possible noise from a transducer can be suppressed in this way.
If there is an overrange or underrange on an integrator input, then integration is stopped (the latest valid value is retained), and will only continue when the input signal is correct again.
17
2 Device description
Operating time counter
The operating time counter will count how long a selected binary input or one of the digital signals is closed (set). The time can be displayed in sec, min, hr or days.

2.5.1 Reporting period of the counts

After an adjustable time (reporting period), the counts are stored for all counters/integrators/operating time counters. The counts for the current and the previous 7 completed reporting periods will be displayed. The following counter/integrator types are possible:
-periodic In addition, the time period (between 1 min and 12 hrs) must be selected in the parameter Period.
-external In this case, the counter/integrator is updated only when the selected control signal is active (e.g. binary input is closed). When the control signal is deactivated (e.g. binary input is opened), the counter/integrator value is saved and reset to 0.
- daily
-weekly
-monthly
-yearly
-total
- daily, from ... to The period also has to be selected, by means of the parameters “Daily start time” and “Daily end time”. The counter/integrator will then be updated from the start time only. When the end time has been reached, the counter/ integrator value is saved and reset to 0.

2.5.2 Resetting the counters / integrators / operating time counters

Periodic reset There is a reporting period for each counter/integrator/operating time counter.
At the end of this period, the current data (value and time) are saved and the value reset to 0. Subsequently, the next period can be recorded.
An exception is the totalizer/integrator. It is saved whenever any count/ integration has been completed, but it is not reset to 0. It enables the totalizer to be evaluated in the evaluation software PCA as well.
18
2 Device description
External reset You can configure one control signal for all 6 counters/integrators together,
with the result that the counters/integrators are reset to 0 without any saving of the previous values. The period for the counter/integrator summation will be restarted at this point. This means that after the test run of an installation, for instance, the recording can be freshly started; the test run values that are not required are eliminated.
v see Page 69 “Generate reset”
Reset from keys
Reset from CompactFlash card menu
Another option for resetting the counter/integrator values is provided at the parameter level. After entering the password, you can define a value for each of the 6 channels. The counter/integrator will then be set to this value. When the value is entered, after editing, a message with the new and the old count is entered in the event list.
The time period for the counter/integrator summation will not be restarted. The previous counter/integrator values will also not be saved.
If you wish to save the previous counter/integrator values, you must execute the function “Update CF incl. counters ...” in the menu for the CompactFlash card.
In this way, the recording can be freshly started for individual counters/ integrators, e.g. after the test run of an installation; the test run values that are not required will be eliminated in the process. You can select a password that is different from that for accessing the configuration. The password is set up in Configuration ➔ Device data ➔ Code
No. (password) ➔ Reset counter / int.
If, in the menu CompactFlash card, the function CF update incl. counters is carried out, then the counter states will also be saved and then reset.
v See “CompactFlash card” on Page 50.

2.5.3 Response to instrument reconfiguration

When the instrument is reconfigured, the current counter/integrator reporting periods remain unaffected. The counter/integrator values will not be reset to 0 and the reporting period will not be restarted.
The values can only be deliberately reset through the Parameterization menu.
19
2 Device description

2.5.4 Response at end of summer time

If a period of less than one hour has been set for counters/ integrators, and the change from summer time to winter time falls precisely within this period, then the PC evaluation software (PCA3000) will forcibly set the end time to be the same as the start time. This prevents a negative period arising, and ensures that further processing is error-free.

2.6 Math/logic module

The math and logic module is available as an extra code. Like the counter/ integrator/operating time counters, the math and logic module is implemented as channels that are not available as hardware but are calculated by the instrument software.
The math and logic module consists of 2 parts:
- the math module for calculating analog values and
- the logic module for calculating Boolean values (0 or 1).
Math module With the help of the math module, measurement inputs can be used for the
calculation of “virtual” math channels. A total of 6 channels can be recorded (stored) in the instrument. In the
configuration, you will find an option under Configuration Analog channels Analog channel 1 — 6 Input signal for selecting which of the analog inputs or math channels should be stored.
If more than 6 channels are to be active in the instrument (e.g. 4 analog inputs and 3 active math channels), then you can also use the visualization in the presentation mode “Large digital display (large measurements)” to see the measurements that are not stored.
v Chapter 3.2.4 “Large digital display (large measurements)”
Recording
20
2 Device description
The following variables are used for the formulae:
- analog inputs (AE1 — AE6)
- math channels (MAT1 — MAT6)
- counter/integrator channels (ZI1 — ZI6)
- binary inputs (BE1 — BE4)
-alarms
-errors
- Modbus flag (signal via interface)
- instrument-specific data (only after consultation with the manufacturer)
If counter/integrator values are used for calculation, then please note that their accuracy is reduced, since, in this case, two different data formats have to be used for calculation. The counters/integrators are calculated in the double­float format, whereas the math module employs a single-float format that follows the IEEE 754 standard. Nevertheless, it is possible to include these values in the math module.
The following fixed functions are available:
-difference
-ratio
- relative humidity (psychrometric measurement)
- moving average
For the moving average, the reference channel has to be entered (in most cases, the analog input number) and the time period (in minutes) for calculating the moving average.
The following operators and functions are available for the formulae: +, -, *, /, (, ), SQRT(), MIN(), MAX(), SIN(), COS(), TAN(), **, EXP(), ABS(), INT(), FRC(), LOG(), LN().
On going above or falling below the scalable values, the math channel is treated as for “out-of-range”.
The formulae are entered in the PC, in the setup program. The mathematical formulae cannot be edited by using the keys on the instrument.
For further information, refer to Chapter 5.9 “Math/logic”
21
2 Device description
Logic module You also have up to 6 channels available as logic channels.
As is the case with all the other digital signals, the calculated digital (Boolean) values can be used for different functions:
- recording in the event traces,
- as a control signal for display switch-off,
- clock time synchronization,
- operating time counter,
- externally controlled counters / integrators
- counter/integr. reset
- event operation and key inhibit,
- for output to a relay and
- as count input for a counter.
The following variables are used for the formulae:
- binary inputs
- logic channels
-alarms
-errors
- Modbus flag (signal via interface)
-TRUE
-FALSE
- device-specific data (only after consultation with the manufacturer)
These functions can be used for the formulae:
-! (NOT)
-& (AND)
-| (OR)
-^ (XOR)
- / (rising edge)
- \ (falling edge)
-( (open bracket)
-) (close bracket)
22
For further information, refer to Chapter 5.9 “Math/logic”

2.7 Operating modes

2 Device description
3 operating modes
The instrument has 3 operating modes:
- normal operation
- timed operation
- event operation
The following settings can, among others, be made for each of the three operating modes:
-stored value
-storage cycle
Stored value The stored value setting determines what is stored: average, minimum,
maximum or momentary value between two storage cycles, or the peak value (envelope). The setting “peak value” means that the maximum and minimum values from the last storage cycle are saved.
Storage cycle The storage cycle determines the interval between two stored values. The
diagram speed corresponds to the storage cycle, which means that with a storage cycle of 5sec, for example, the stored value is entered in the diagram every 5sec.
Normal
Normal operation is active whenever event or timed operation is not active.
operation
Timed operation
For timed operation, a period of time can be defined (up to 24 hrs) within which a specific stored value and a specific storage cycle are active.
Event operation Event operation is active as long as its control signal (v Chapter 4.2.6
“Configuration - Recording”) is active. Event operation can be used, for example, to shorten the storage cycle when an alarm is present.
Priority The respective priorities of the operating modes are allocated as follows:
Operating mode Priority
Active operating mode
Normal operation
Timed operation average Event operation high
The active operating mode is shown in the diagram by the background color for the diagram speed:

2 Device description

2.8 Storing data

Life-cycle data management
The integrated life-cycle data management puts users in the position of being able to save all the process data from the system that is being monitored in an archive file on their PCs or a server system.
The recovery of configuration-dependent system data, which may be required for commissioning, maintenance or optimization during the life-cycle of a system, is now enabled by the associated PC evaluation software (PCA3000) in a dialog window.
24
Operating principle
2 Device description
The measurements from the analog inputs are acquired continuously in a 250msec sampling cycle, and then stored in the main memory. These measurements also serve as the basis for limit monitoring.
Main memory (FLASH memory)
CompactFlash card
Data security The data are stored in coded form in a proprietary format. If the CompactFlash
Storage cycle Different storage cycles, ranging from 1sec to 32,767sec can be configured
The data stored in the main memory are regularly copied to the CompactFlash card in 4 kbyte blocks. The main memory is written to as a ring memory, i.e. when it is full, the oldest data will automatically be overwritten by new data. The capacity of the main memory is sufficient for approximately 350,000 measurements. The instrument monitors the capacity of the main memory and activates the “Memory alarm (internal)” signal if the level falls below a configurable residual capacity.
For saving the data, CompactFlash cards (industrial grade) can be used with the following storage capacities: 64/128/256MB.
The instrument monitors the capacity of the CompactFlash card, and activates the “Memory alarm (CF card)” signal if the level falls below a configurable residual capacity. This signal can be used, for instance, to operate a relay (warning signal “Swap CF card”).
card is removed from the instrument, no data will be lost immediately, as these data are still stored in the FLASH memory. A loss of data will only occur if, after the CompactFlash card has been removed, the FLASH memory is completely rewritten as well, and no data have been read out through the interface.
for normal, event and timed operation under “configuration”. The storage cycle determines the time intervals at which the measurements
are stored.
Stored value Under this parameter, separate configurations are made for normal, event and
timed operation, to decide which value is stored (average, momentary, minimum, maximum, peak values).

If peak values are recorded, then the times are shorter, since a maximum and minimum value is recorded each time. The recording capacity will be further reduced if a large number of event messages are also stored.
The recording duration can be optimized by process-oriented selection of the storage cycle.
In normal operation (no error, no alarm, ...) a storage cycle that is as long as possible (e.g. 60sec, 180sec, …) should be selected, depending on the particular application.
In the event of an alarm or error, the storage cycle can be shortened via event operation, with the effect that the measurement data are recorded with a high time resolution.

2.9 Read-out of data

In addition to automatic read-out via the external CompactFlash memory card, measurement data can also be read out through one of the interfaces (RS232, RS485, setup, Ethernet).
Both read-out options (card/interface) work in parallel. For this reason, there are also two “digital signals”, which indicate when the available storage space has fallen below a certain configurable value.
Memory alarm The limit for alarms can be set by the parameter Configuration ➔ Device data
➔ Memory alarm in the configuration level.
The parameter Configuration ➔ Memory upload can be used to determine which storage space indication should be shown in the status line. The “digital signals” for storage space detection function independently of the indication in the status line.
Digital signals IntMemAlm/CF
If this signal is set, it means that no data have been fetched by the CF card for a long time, and the available capacity of the internal memory has fallen below the configured level.
IntMemAlm/ser
If this signal is set, it means that no data have been fetched by the interface for a long time, and the available capacity of the internal memory has fallen below the configured level.
MemAlmCFcard
If this signal is set, it means that not enough space is avialable on the CF card. The program PCA3000 can help here. Use PCA3000 to read in the data, save them to the hard disk on a network, and free up the space on the CF card. Alternatively, you can use a new CF card.
Data lost A loss of data is only imminent if all three of the above signals are set.
Read-out via interface
Use the PCA Communications Server software (PCC) to read out measurement data via the serial, setup or Ethernet interface. The software has been developed especially for the paperless recorder.
v Please refer to the Operating Manual 59500 for further information.
Use the same archive (in the PC) for reading out via the interface as for reading out with the CF card. This saves having to put together data from different files at a later date.

2.10 Evaluating data

Please use the PC Evaluation Software (PCA3000) for evaluating the data on the PC. The software has been developed especially for the paperless recorder.
v Please refer to the Operating Manual 59498 for further information.

2.11 Webserver

If the paperless recorder is equipped with the extra code “Ethernet interface”, and the device-internal Ethernet software (“Ethernet version“) has the number
183.02.03 or higher, then the paperless recorder has an inbuilt webserver. The
webserver can be started by entering the IP address in an Internet browser on the PC (e.g. http://10.10.90.45).
The variables that are shown are acquired and displayed automatically by the webserver. The latest data are read out of the instrument every 5 seconds. Any limit infringements show a red background. A maximum of 6 channels (analog or math channels), up to 6 counters or integrators, and a maximum of 6 event traces.

Since the paperless recorder is only polled by the Internet browser every 5 se­conds, it is possible that, for instance, the PCC data transfer software takes over control of the paperless recorder during this interval. After securing the da­ta, PCC will end access to the recorder, so that the Internet browser can read out data again.
Only 1 PC (client) at a time can access the device (server) via the Ethernet interface.
