2General Presentation JUMO Screen Recorders

� This presentation shows important functions of JUMO-

Screen Recoders and demonstrates their application

� The exemplifying description of configuration and

operation applies for the LOGOSCREEN 500 cf

Advices for the presentation

� Both – LOGOSCREEN 500 cf and LOGOSCREEN nt offer

the functions described

� Configuration and operation are slightly different from

those of the LOGOSCREEN nt

� Most of the explanations are based on concrete

examples


Application Example

� Two temperatures (PT100 each) and a pressure (4…20

mA = 0…500 mBar) shall be recorded

� Basicly the measured values shall be recorded every 20s.

If the temperature 1 is > 100°C, the values shall be

recorded every second.

� If a potential-free contact is closed (binary input 1) , the

following text shall be adopted in the event list: „ Ready

for operation“

Configuration of the Inputs

Configuration Input 1-2


Configuration Inputs

Within the setup-program please go to the submenu „analogue inputs“. There your are

requested to proceed as follows:

Select the input you want to configure; in our example we use the inputs 1-3.

Under input 1 and 2 (menu item: sensor) – please select „resistance thermometer“. The

thermometer is connected in 3-wire circuit; please take the corresponding adjustment.

The correct temperature for all common resistance thermometers and thermocouples is

automatically built on the basis of the measured resistance values or voltages. For a PT100 you

can keep the basic adjustments under menu item „linearization“.

Our signal shall be recorded within a range of 0…200°C; please put in the relevant limit under

menu item „Range“.

Configuration Input 1-2


Configuration of the inputs

Configuration Input 3

20 mA equals 500

4 mA equals 0


RecordingHow to assign temperatures and pressure signal to the channels

� our devices offer a certain number of analogue- and binary channels

� in our example the signals of the analogue inputs 1-3 are assigned to the analogue

channels 1-3

� the channels 4-6 are disconnected (input signal: no signal):

Dispaly at the deviceConfiguration


Recording

Signal binary input 1 (ready for operation) assign event trace

� Binary input 1 is assigned to the event trace

� The event traces 2-6 are disconnected:

Configuration Display at the device


Recording

Normal operation

� Normally the screen recorder shall record a measured value every 20 s; in the submenu

„Normal operation“ we put in the corresponding specifications

Normal operation is required – memory status„on“

Storage cycle for the measured value shall be20s


� The screen recorder scans the input signals every 250 ms (in 20 s 80 samplingrates)

• Under „Memory value“ you can define which of these 80 sampling rates shall bestored:

The mean value of the 80 signals

The instantanenous value

The minimum value of the 80 signals

The maximum value of the 80 signals

The maximum and the minimum of the 80 signals (peak value)

Recording

Normal operation – Memory values


Recording

Event Operation and Alarms

� If a binary signal is active, the recorder can be changed into event operation

� In this case memory value and –cycle can be changed

In our example the recorder changes into event

operation, if there is a high alarm at input 1.

Peak values are still stored; however, thestorage cycle for the measured values is 1 s


Recording

High-Alarm

� In our example we change into the event operation, if there is a high alarm at analogue

input 1

� In order to configure the alarm, we must select the used channel:

Text 1 is defined in the menu „texts“


Effects at the device

Alarm changes into event operation, text indicated in event list

If the limit of 100 °C is exceeded, an alarm occurs

The Signal „Max-Alarm 1“ changes the device from normal operation(Storage in the example every 20 s) to the event operation (in the examplethe measured value is stored every second). In the event operation thecolour of the chart speed display changes to orange

The configured text is taken over in the event list


Recording

Time operation

� If – e.g. the storage cycle – is changed for a certain period of time, the timed operation

applies

� In our example during the time from 20:00 hh until 06:hh the value shall be recorded every

180 s only

� Please make the following adjustments:


Recording

Priorities, event operation, timed operation, normal operation

If all three kinds of operation apply, the recorders are working as follows:

� Actual time not within the timed operation, control signal for the event operation is not

active � Normal operation

� Actual time within the timed operation, control signal for the event operation is not active

� Timed operation

� Control signal for the event operation is active � Recorders work in the event operation

� The event operation has top priority


External Texts

Take-over of a text as result of the binary signal

� If binary input 1 closes, the text „ready“ shall be taken over in the event list:

Indicate the number of the customer text which shall be taken over in the event list in the event of a positive or negative edge at binary input 1

Define customer text

Event list of the device:


Data transfer to the device

Transfer via interface

� In our example new data (configuration) are transferred to the device

� A new configuration for the LOGOSCREEN 500 cf is created

alternatively

How to show and/or remove the event traces

� Event traces can be shown or removed with the push-button

Event traces


Operation

Calling the event list

� you can reach the event list by two possibilties:

1. Selection by push-button:

2. Menu navigation Button menu


Data Memory

Explanation I/II

To help you to understand history and operating principle of the menu Compact-Flash-Card,

the following pages will provide you with important explanations about the data storage:

� The recorder has a flash memory which work as a ring buffer

� If a block of 4 Kilobyte is completed, a copy of these datais stored on the external CF-Card


Data Memory

Explanation II/II

� The memory range with the copied data isconsidered as free memory

� The part of free memory is displayed on thescreen for your information:


Operation

History Function

Data in the main memory can be checked with the history function:

Scroll buttonsZoom is possible

The diagram can bescrolled to certainpoint of time


Operation

Data memory on CF-Card

� As mentioned already, the data are automatically copied from the internal memory to the

external CF card

� However, this done only, if one data block is completed with 4 kB

� If you want to make sure that all data are on the CF-card before removing the card, please

select the corresponding submenu in the menu CompactFlash-Card:


Further Functions

� Now the recoder works acc. to the requested configuration

� On the following pages further functions of the screen recorders

are described

� The data of the CF-Card can be evaluated with the evaluation

software PCA3000


Configuration Transfer with CF-Card

� A configuration by setup can – alternatively –

be transferred with the CF-Card:

� Read-in of the configuration in to the recoder as follows:

Menu � CompactFlash-Card �“CF-Card → Config-Data“


Configuration Transfer with CF-Card

� The code can be changed with the setup program:

� Before the menu starts, the

corresponding code must be put in:


Relay Outputs

� Screen recorders can be equipped with relay outputs

� A multiplicity of functions can be assigned to the outputs

Example: A high alarm at input 1 occurs

�� Relay 1 switches


Mathematics / Logic

Mathematics - Principle

Max. 70 digits


Mathematics/ Logic

JUMO-Screen recorders offer a mathematics/logic function (option with costs). With the

setup-program several mathematics- and logic formula can be defined.

In the formula-editor (left) you can find the variables which can be integrated in the formula.

The allowed operators are indicated in the right window.

All mentioned terms can be imported into the formula with „Adding“. In our example we will

use the mathematics formula to create the mean value of the signals at analogue input 1 and

analogue input 2.

With the logic formula you can realize logic functions (Example: Logic 1 shall be active, if the

binary inputs 1 and 2 are active).


Mathematics / Logic

Mathematics – how to enable?

Mathematics/Logic for JUMO screen recorders can be releasedafterwards:

Enter enable code (Release)

Generate the code number


Record Mathematics

� In the registration the maths value is

assigned to a channel:

� Display of the maths result at the

recorder:


Configuration from the device front

� Configuration of the JUMO-Screen recorders can be realized in a big scope from the front

of the device

� Adjustments are to be made in the menu „Configuration“:

Works adjustment 9200; please refer in

the setup to submenu „instrument data“


Display switch-off

� The display switch-off is energy-saving (a good portion of the power consumption is

allotted to the display) and saves the display.

� There are two possibilities:

If the user does not tap a key, the display will be switched off after a defined period (here 5 min.). After pressing a key, the display will be switched on again.

As long as the control signal is activated (here binary input 1), the display is switched off.


Time Synchronisation

� In the menu „Extras“ a new time for the screen recorder can be defined:

� If the time is changed, a new

configuration is created

� Due to a binary signal the recorders can be synchronised on the clock minute:

� The synchronisation signals occurs on the clock minute

� If the time of the recorder is in the second half of the minute,

the time is set ahead to the clock minute

� If the time of the recorder is ahead up to half a minute,

the time is reset to the clock minute

� Time synchronisation does not create a new

configuration!
