SW 700-001: KI recorder

Select menu: Parameter setting/FRONT M 700/KI recorder

Additional function SW 700-101

The KI recorder follows the course of the process and releases a messages in the event of a deviation. It is called up from the measurement recorder: meas.

Continuous processes

The measured signal is surrounded by a dynamically tracked, processcontrolled tolerance band. Slight fluctuations are tolerated. If the measured value leaves the tolerance range, a message is released (Fig.).

The recording interval can be set from 10 s to 60 h.

Variable Message

Tolerance band around the measured signal generated by a low-pass filter

Measured signal

Fig.: KI recorder, continuous process t

Batch processes

The KI recorder provides an automatic self-learning function. This allows checking whether regularly recurring processes keep the preset tolerances.

Deviations from the normal course of process (plus preset tolerances) generate a message (Fig.). Maximum process duration can be set from 1 to 60 h.

Evaluation

Within the KI recorder function you can evaluate a reference curve directly on the device.

To do so, use the arrow keys (Up/Down). The reference curves and the most important parameters are displayed one after the other.

External control

The Start/Stop function can be remote-controlled via the OK2 input (BASE module) or via the PA 700 (X) PROFIBUS module.

(To set the control element, call up:

Parameter setting / System control / Function control matrix).

The softkeys will then be deactivated.

The K1, K2, and K3 contacts of the BASE module can be assigned to the “KI rec active” signal.

• Save / load reference curves

Up to 5 batch reference curves can be stored on and retrieved from a SmartMedia card:

Parameter setting / System control / KI batch recording.

The reference curve, envelope, time response, and KI settings are stored.

• Archiving of completed batch processes

Complete batch results can be archived on the SmartMedia card. All reference values and current batch data are stored in the archive.

Select menu: Diagnostics/Module pH/Tolerance band recorder

Tolerance band recorder

(Adjustment of tolerance band: see following page)

Tolerance band calibration prevents that slight calibration scatter of zero and slope immediately leads to a readjustment of the calibration data and thus to a shifting of the measured value. If the zero and slope values determined during calibration remain within their tolerance bands, the new data are not stored. If one of the calibration values lies outside the tolerance band, the new data are taken over.

Drift due to aging or calibration scatter can be identified at a glance, thus allowing to draw conclusions as to electrode life and the required calibration interval.

In the Calibration record you see whether the data have been stored or whether the old data can still be tolerated.

, HNO

, HCl, NaOH, NaCl from the measured conductivity and temperature values.

Conditions for concentration determination

Below you find tables with the concentration ranges of the preset substances.

These tables show the conductivity of the substances versus substance concentration and process temperature:

• For calculation of concentration, the medium to be measured must be a purely binary mixture (e.g. water-hydrochloric acid). Presence of other dissolved substances (e.g. salts) leads to incorrect concentration values.

• In the region of small slopes (e.g. at the range limits) small conductivity changes can correspond to great concentration changes. This may lead to an unsteady display of the concentration value.

• As the concentration value is calculated from the measured conductivity and temperature values, accurate temperature measurement is very important. Therefore, you should make sure that sensor and process medium are in thermal equilibrium.

Messages

You can define limits for warning and failure messages for the concentration value:

SW 700-011: High CO2 compensation

Application-specific additional function for breweries

This additional function simplifies parameter setting since all steps not required for measurement of beer are omitted. It simultaneously acts on all installed O

2 module (module software version 2.2 and higher).

Function principle:

During the filling process it must be ensured that as little oxygen as possible is dissolved in the beer to extent its shelf life.

During oxygen trace measurement the sensor is operated with a very low polarization voltage (-500 mV). This results in low cross-sensitivity to CO

2

.

For a calibration in air, this polarization voltage is too low.

It must be set to -675 mV and afterwards be reduced again to -500 mV for measuring in the trace range.

A sufficiently long waiting time must be observed until the sensor has stabilized.

Opening and closing of valves causes pressure variations in the beer pipes which momentarily falsify the O

2 signal. Therefore the input signal must be attenuated correspondingly to suppress transient interferences.

These processes are automated by the additional function, i.e. all parameters required for the respective program step are set automatically. When the additional function has been activated, the parameter setting steps are displayed as follows:

SmartMedia card: Usage

Use as memory card in combination with additional functions.

Additional functions must be ordered separately (release via TAN).

A SmartMedia card is provided with the following additional functions:

• Software update (SW 700-106, see Pg 43)

• Additional function SW 700-1xx (description Pg 34 et seq.)

Using commercially available SmartMedia cards

Commercially available SmartMedia cards can be used as additional memory card.

The following types of cards are supported: 8 MB, 16 MB, 32 MB, 64 MB,

128 MB. Externally produced files, such as from a digital camera, are tolerated. Long file names can be read. The M 700 generates file names in the

8.3 format (8 characters file name, 3 characters program-specific file name extension).

Formatting a commercial SmartMedia card

Some devices (e.g. digital cameras, scanners) cause a formatting of the

SmartMedia card which does not correspond to the SSFDC specification or the SmartMedia Interface Library (SMIL). The manufacturer therefore recommends to format a commercial SmartMedia card as M 700 memory card prior to first use.

Additional function SW 700-103: Measurement recorder

The measurement recorder saves all entries in a file. The last 200 entries can be displayed on the M 700. A new file is generated for each day. The date is encoded in the file name.

Example for a file generated on SmartMedia card:

\RECORDER\R_YYMMDD.TXT

Recorder data of YYMMDD

(YY = year, MM = month, DD = day)

The data is recorded as ASCII file with the extension .TXT.

The individual columns are separated by tabs. This makes the file readable with word processing or spreadsheet programs (e.g. Microsoft Excel). Each time the memory card is inserted in the slot, a “Device Info” consisting of

Model number, BASE serial number, and tag number. Thus, a memory card can also be used to collect the measurement recorder data of several devices.

AuditTrail

Function description

Electronic data recording and protection according to

FDA 21 CFR Part 11

Pharmaceutical applications not only require a hygienic design, but also the protection and complete recording of data (FDA regulation: 21 CFR Part 11).

The M 700 with stainless steel enclosure and SmartMedia card meets these demands. The FDA regulation basically consists of two parts: “Audit Trail” and “Electronic Signature”. Both parts interact directly: For every change of parameters, the device records what has been changed and who has changed it.

Functions like calibration (adjustment) often may only be performed after written approval! This approval is given by an electronic signature.

AuditTrail card

The AuditTrail card is a specially prepared SmartMedia card. The M 700 records the AuditTrail log on an “AuditTrail card” only. Readability from PC is not affected.

Note:

Only specially coded SmartMedia cards supplied from Mettler Toledo can be used as AuditTrail cards.

As delivered, the AuditTrail card includes a PC program which makes the recorded AuditTrail data readable. When log coding has been activated, it also allows decoding of the data. The program supports the data export to other programs, e.g. Microsoft Excel.

46

M 700(X)


Signature

Function description

Signature

A signature consists of two entries, the user name and the corresponding passcode. For each change at the device (calibration/adjustment, parameter setting, maintenance, if required also diagnostics), the M 700 records in the

“AuditTrail Log” and in addition in the logbook who has performed the change. For that purpose, access authorizations are introduced.

Access authorization

Every access authorization consists of a signature:

• User name and

• Passcode.

The administrator and the user enter the access data in the user management menu. The administrator enters the user name (short name) and the user adds his/her personal passcode.

Each time he/she calls up a protected menu, the user must enter his/her name and passcode. The M 700 only gives access to the function if the access codes are valid. The recordings (AuditTrail log, logbook) on the

AuditTrail card include the user names so that all actions can be clearly traced back.

Coded storage

The entries in the AuditTrail log can be coded using an algorithm and protected with checksums so that a special evaluation program can prove the authenticity of the data records on a PC.

To protect the data against unauthorized query or modification, access data must be entered before a main menu from the menu selection is opened.

Two-stage security is provided by input of user name and passcode.

The passcode is not visible. It is only displayed as 4 dots. The administrator can delete each user’s passcode (with entry in

AuditTrail log). The user is identified by his/her access data.

After entry of the valid signature all menus are available with the defined user rights. Only in measuring mode, the rights will be erased again. This allows accessing several menus without having to enter the access data each time.

When an invalid combination of user name and passcode is entered, access is denied with the text “Wrong passcode”. The entry “Wrong passcode” with the entered (wrong) user ID is recorded in the AuditTrail log.

• “AutoComplete” is an input assistance for the user name as known from some

Windows programs.

• Access to the Diagnostics menu can be

“free” or require input of a “Signature” according to the access authorization granted the User Management menu.

• For the recording on SmartMedia card, a coding can be activated so that the data cannot be read or queried without corresponding programs.

User management

An administrator and up to 5 users can be entered in the M 700. Each user has a user name (max. 8 characters) and a passcode (4 characters). Each user can be granted access and usage rights for each main menu level. The combination of user name and passcode is the user’s “Electronic Signature”.

Every logged modification is signed and can be clearly traced back. Different access rights for each menu can be defined for each user.

Functions

AutoComplete

The “AutoComplete” function facilitates the input of the user name. You only have to enter as many letters as the M 700 requires to identify the name.

This function can be switched off in the AuditTrail menu because the automatic display of the user name reduces system security, which then might not be sufficient for FDA documentation.

Access to diag menu

To protect all data against unauthorized query, it is also possible to protect the diagnostics level with a passcode (this will also affect the Favorites menu). As delivered, access to the diagnostics level is free.


The AuditTrail log is an additional - protected if required - recording of all data on the AuditTrail card (SmartMedia card). The log is recorded in the currently selected language.

The data can be coded (to protect against unauthorized query) and secured with a checksum (to prove the authenticity of the data). The coding can be switched on or off in the AuditTrail menu of the Administrator level.

A four-digit line numbering (0000 ... 9999 P 0000 ..., cyclic) ensures uninterrupted recording. The AuditTrail log cannot be deleted by the M 700.

A buffer storage is provided to store the recorded data while the AuditTrail card is being replaced, for example. An error message “Fail AuditTrail card” is generated when the buffer is full. The oldest entries in the buffer will be recorded. They are then missing in the log (the corresponding line numbers will be missing).

When an empty AuditTrail card is inserted, the buffer storage and the current entries are transferred to the empty card.

Parameters

The AuditTrail log cannot be queried by the M 700. It can only be evaluated using the suitable PC program. According to FDA 21 CFR Part 11 the user must ensure the transport of the data from the M 700 to evaluation and further processing or archiving. Furthermore, the user must ensure that the log data cannot be deleted from the memory card. The PC evaluation program is able to decode the data and verify the security parameters and thus to prove the authenticity of the data on the card. It allows printing the encoded data and exporting them to other PC applications.

Logbook

The logbook is provided in addition. In AuditTrail systems it runs simultaneously with the audit trail log in contrast to which it can be queried provided that the diagnostics menu is accessible. The administrator is permitted to delete the logbook data since all security-relevant data are stored in the

AuditTrail log.

Recordings in the AuditTrail log

Caution!

Data loss (even total destruction) if the card is not closed before it is pulled out. (Maintenance menu, “Close card”)

The following entries and messages are recorded:

• Measuring point, device description, module equipment and serial numbers

• Menu system log-ins

• Movements within menus (menu headlines)

• Modified parameters at the press of enter

• Calibration record at the end of a calibration or adjustment incl. user name, sensor type and serial number

• Messages such as failure and maintenance request
