The time range displayed on the Logoscreen 500cf is determined by the programmed memory cycle.
Different memory cycles can be programmed for the three possible
operating modes: "Normal operation", "Time operation" and "Event
operation". This allows, for instance, to save measured values more
frequently, e.g. in the event of overrange or in a specific time frame,
and, thus, have available a higher resolution within the time axis.
Do the interface parameters (log, baud rate, data format, device
address, etc.) in the communication server program JUMO PCC correspond
with the settings in the Logoscreen 500cf?
If necessary, refer to the operating manual, chapter 4.2.10 (Configuration - Interface).
Is the connection, interface type (RS232/RS485) and connection, correct?
For the RS485, an additional external interface converter to RS232 or USB is often required for connection to a PC.
The recording time depends on several factors:
Please refer to chapter 2.8 in this operating manual for the orientation values listed in a table.
Take into consideration, that the internal memory in the Logoscreen
500cf operates as a ring memory, whereas the measured data saved on the
external CF card cannot be overwritten automatically by the Logoscreen
500cf.
Thus, the old data remains saved on the CF card if the recording time is
exceeded, whereas the internal memory contains the latest data.
Measured data is lost for the time inbetween.
Compact Flash memory cards (Industrial Grade) up to max. 2 GB can be used.
Format: FAT or FAT16
For a high data security, we recommend to only use the CF cards
available from JUMO as accessories for this recorder. These CF cards
were tested together with the Logoscreen 500cf and have been proven in
practice.
1. Release of integrators and counters as well as the maths and logics module.
Release of these software options at a later time is possible with the setup program and also directly on the device using the keys.
1.1 Proceed as follows to release the options using the keys on the device:
A code number is read out first from the logoscreen 500cf. For this purpose, invoke the following menu:
Configuration level à Device data à Option release à Determined code No.
The number code displayed here including the possible prefix is sent to JUMO by telephone, fax or mail.
JUMO will generate a device-specific release key from this code No.
Then, enter this release key into the respective field on the device to release the option. The option is immediately available and can be configured and used as required by the user.
1.2 Option release via the setup program:
The extra code "Maths", "Counters/integrators" can be released at a later time using the Logoscreen 500cf setup program and an interface connection to the recorder.
Complete wiring of the Logoscreen 500cf is not required for the option release. It is only necessary to connect the recorder voltage supply.
The interface connection can be easily established with a JUMO USB-TTL or JUMO RS232-TTL interface via the serial programming interface.
An optional RS485/RS422/RS232 interface can be used for establishing the connection as an alternative to the JUMO interface lines.
A code number for maths and counters/integrators can be generated (= read out) in the setup program under the "EXTRAS" - "Release of extra codes" menu point. The displayed code number including the possible prefix is sent to JUMO by telephone, fax or mail.
JUMO will generate a device-specific release code from this code number.
Enter this release code in the setup program in the field following "Enter release code" on the PC to release the option.
2. Upgrade from three to six analog inputs
If required, Logoscreen 500cf delivered with three analog inputs can be upgrades at a later date to six analog inputs by the JUMO service personnel.
3. Upgrade of 4 binary inputs, 3 relays and a serial interface RS 232/485 (modbus, J-Bus)
If required, the system can be upgraded at a later time to the extra code "261“ (=> 4 binary inputs, 3 relay outputs, serial interface RS232/485) by the JUMO service personnel.
A malfunction is pending that is precisely displayed in the device info window.
(e.g. "Battery flat“)
Furthermore, general information about the device, e.g. software version
number and hardware equipment is displayed in the device info window.
Also refer to the operating manual, chapter 3.7.
An inspection certificate 2.2 of an acceptance test certificate 3.1.B can be issued for the LOGOSCREEN 500cf upon request.
For this purpose, send the device to JUMO including a list of the specified measuring points to be moved to.
It is possible to calibrate complete temperature measuring strings in
the user factory as well as in our plant in addition to the calibration
of the individual paperless recorder. For this purpose, a DKD laboratory
is available in the JUMO main factory in Fulda.
Up to 6 analog signals can be recorded simultaneously by the Logoscreen
500cf. This also applies to devices with released maths option.
With the version equipped with 3 analog inputs and released maths
module, for example, it is possible to record 3 values calculated in the
maths module in addition to the three analog inputs.
The configuration level on the device and the "Precise adjustment"
subroutine can be used to adapt each individual analog input to
reference signals. This device-specific precise adjustment is
exclusively carried out using the keys on the recorder to avoid
overwriting or transmitting this adjustment unintentionally.
The precise procedure is described in the operating manual, chapter 4.2.11.
The following PC software is optionally available for the Logoscreen 500cf:
The following applies to all three software products:
The current version is always available for free download on the JUMO homepage. A licence number, which has to be purchased, is required for use as full version. The purchased licence number will remain valid during an update.
The PCA3000 can be used for displaying PCA archive data without licence number for transmitting recorded measured values, e.g. to customers or authorities.
The counters and integrators can be preset or reset via the
"Counter/integrator reset" in the parameter level directly on the
Logoscreen 500cf.
There, new entries can be easily made for the individual counters and
integrators. This intervention is documented in the event list.
Further information about this subject can be found in chapter 2.5.2 of the operating manual.
If two lines or two columns appear per input signal on the recorder or when evaluating the PCA3000, the following reason applies:
The setting Peak values is factory set under "Recording" - "Normal operation" - "Saved values:". With this setting, the min and the max value is determined and saved in each memory cycle.
This peak value recording is particularly suitable for applications, to which the following statements apply:
For several "Standard applications", we recommend to select the setting "Average Value" under "Saved values:". Then the Logoscreen 500cf calculates the respective average value from the measured values collected in the memory cycle prior to saving and saves only one value per cycle. In this case, only one line per channel is displayed.
Type PING,
Then enter a space by hitting the space bar once,
Then type in the IP address. (Example: ping 10.11.1.77)
If the host name is known, a PING can also be set on it.
The command syntax consists of: PING Space Host Name, e.g. ==> ping jumo device

The standard web server function of Logoscreen nt 706581, allows online display of the recorder screen with regard to measurement data visualization.
You can select and change the view on the PC independently of the current display on the paperless recorder.
For security reasons, changes can only be made to the configuration via the Setup program or directly on the recorder.
Brief introduction to the topic of the web server using as an example, Logoscreen nt and a PC within a company network:
1. The Microsoft Internet Explorer is required as the web browser
2. As SVG images (SVG = Scalable Vector Graphics) are used within the web server, to display these correctly, the web browser needs a plug-in such as the SVG Viewer from Adobe (http://www.adobe.com/svg)
3. Establish a direct Ethernet connection between the PC and Logoscreen nt, as described below this article
4. If the current IP address of the Logoscreen nt is now entered in the Internet Explorer, a window opens to query the user name and password for logging in to Logoscreen nt.
(Factory setting: user = Master, password = 9200)
Online visualization is then set up. Here you can toggle between the various presentations.
The aim in Eco mode is to keep the number of saved measurements as low
as possible, whilst still clearly showing the course of the signal.
The number of measurements stored is dependent on the dynamics of the measurement signal.
If the measurement signal is very stable, the measurements are only stored at relatively large intervals. This is preset by "Min. Storage cycle" in normal group configuration mode.
If the measurement differs from the defined "Tolerance band" by longer than is set under "Storage cycle", additional measurements are stored. The reference point for the tolerance band is always the last measurement to be stored.
If the detailed course of the signal is less important than monitoring
limits, the number of stored measurements can also be reduced by
storing the "Min/max values" in conjunction with a longer storage
cycle, thus saving memory space and possibly transmission time.
More detailed information on the topic of "Eco mode” can be found in section 2.8.2 of Operating Instructions B 70.6581.0.
Infos for the “Flow Rate Quantity B.” function on the JUMO Logoscreen nt
The ”Flow Rate Quantity Bx” function is found in the “Counters/Integrators” menu
As well as recording the current flow and flow rate, this can also be used to implement a rate indicator or an indicator for quantities per unit of time.
The math option can also be used to absorb the calculated value into a group as a line representation and thus display it together with analog input signals.
Extract from the operating instructions:
At one pulse per revolution, the rate could be displayed and stored as follows in revs/minute as a line (= like an analog signal):
LON to LOGOSCREEN nt
There are two possible variants,
Polling the communication module
Advantage:
- Fast polling cycles
ITOOL_Project for polling the communication module
With iTOOL, a project is created with the Modbus gateway and the input modules.
In the example here, with 2 x 8-fold input modules.
Bindings must be created in the iTOOL project for polling the communication module.
Analog input module 1 is preferably connected to Real_In01 – Real_In08.
Clear sorting is obtained by placing 00 in front of the name for the bindings.
E.g. à in001 (shown in the project example).
The second module corresponds to Real_In09 – Real_In16.
Configuring Logoscreen nt
To poll the communication module and the input modules, it is important to know the Modbus slave address.
This is permanently assigned in the background when creating the iTOOL project.
A list of the requisite addresses is displayed in the print preview.
To see this, proceed as follows. In the Network menu, select Compile....
Confirm the note from iTOOL with OK and close the window with Close.
In the Project menu, select Print-Preview... and check Module list. Uncheck the other options and confirm with OK.
You will then see a list of the modules.
In the Address column, you will see the associated internal slave addresses (red frame) of the modules.
Activating the Modbus master configuration in the Setup program
The slave address found in Print Preview is now used as the instrument address for the Setup program entry in the Modbus master configuration. The Modbus address can be found in the system manual (sh70.4040d.pdf ).
The following Modbus address table applies for polling the communication module.
(sh70.4040d.pdf page 51 )
Number of Values is the input option for polling successive ModBus addresses; with the communication module, it makes sense to enter 16 values here.
The following table applies to polling the 8-fold modules.
(sh70.4040d.pdf page 61 )
The following table applies to polling the 4-fold modules.
(sh70.4040d.pdf page 45 )
Number of Values is the input option for polling successive ModBus addresses, in the example here, 8 values for the 4-fold module corresponds to 4 values.
Tabs 2 - 8 are then inactive.
The standard web server function of Logoscreen nt 706581, allows
online display of the recorder screen with regard to measurement data
visualization.
You can select and change the view on the PC independently of the current display on the paperless recorder.
For security reasons, changes can only be made to the configuration via the Setup program or directly on the recorder.

For more information, see section 6.14 of Operating Instructions B 70.6581.6, under “Web server”.
These operating instructions can be selected from the Setup program under "Info" - "Software Documentation".
Two device languages are stored in Logoscreen nt (these are normally
GERMAN and ENGLISH). You can toggle between these two languages on the
instrument.
Menu in Logoscreen nt:
Using the Setup program and the "Sort language" function, you can
specify which language is to be transferred to Logoscreen nt as
Language 1 and which as Language 2, together with the other
configuration data.
Then, on the Logoscreen nt, you can later switch between the two
languages defined in the Setup program as Language 1 and Language 2.
Only Languages 1 and 2 are transferred to Logoscreen nt with the setup data.
Menu in Setup:
Batch texts can be entered and edited via the Setup program in Online mode
Enter batch texts for the current batch via the Setup-program with the PC keyboard
Establish the Online connection to Logoscreen nt and in the Tools menu, activate the Write interface texts option.
Edit the batch text on the PC and send it to Logoscreen nt
Why does the measurement display on the Logoscreen nt screen go missing after you change the view on it?
View in the PCA 3000 evaluation software:
To enable the Logoscreen nt to store measurements in normal mode, the "Status" parameter must be changed from the factory setting of "Display only" to "Display, Save" in the particular group.
Apart from that, the storage status for normal mode must remain set at "ON".
The time between the two lines of the grid comes from the current storage cycle multiplied by 60.
Examples:
With a set storage cycle of 0 seconds, the LOGOSCREEN nt operates at 125 milliseconds. This results in 7.5 seconds per grid.
With a storage cycle of 10 seconds, there are 10 minutes between the two grid lines. This means that about 24 minutes are displayed on the screen.
A display range that is not dependent on the actual storage cycle can be obtained as follows:
Settings can be made in the ONLINE dialog box or via the CF card and are only accessible with the Setup program via the "Tools" menu item in the way shown below:
