2 General
2.1 Applications
The LON interface is available for the connection of external modules of the
JUMO mTRON automation system, in order to expand the screen recorder
functionality.
All mTRON modules can be connected.
2.2 System requirements
The following requirements have to be met for the connection of external mo-
dules to the screen recorder :
- Screen recorder with LON interface
( program version1from 100.02.01)
- Configured modules of the JUMO mTRON automation system
2.2.1 Configuring the mTRON modules
The mTRON modules are configured using the JUMO mTRON-iTOOL project
design software. An interface cable is required for connecting mTRON modu-
les to a PC.
1. The program version can be requested in the menus of the screen recorder via
Instrument info #Version number.
HThe JUMO mTRON-iTOOL project design software can only be
dispensed with if the mTRON modules have been configured by
M.K. JUCHHEIM GmbH & Co prior to delivery. In order for this to
happen, the customer must have specified the required configura-
tion in detail when ordering his measuring system.
HThe screen recorder can also operate without internal analogue
channels. In this case, the measurements are obtained exclusively
from the mTRON modules.

2.3 Identifying the interface
The LON interface is available as extra Code. The contents of the menu
Instrument info rInterface show whether it is implemented in the system.
If the entry Instrument info rExt. I/O supplement is set to Yes, the LON inter-
face is available.

3 Connecting the interface
3.1 Connection diagram
The screen recorder is connected to the modules of the
“JUMO mTRON automation system”series using the connections Net_A and
Net_B. The technical details are described in the corresponding installation in-
structions for the mTRON modules. Further information on bus termination
can be taken from the Section 3.2 “Connecting configured mTRON modules”.

HWhen connecting the LON interface, care must be taken not to mix
up connectors 20 and 21. Connector 20 is reserved for the serial
interface. Measurements, as well as instrument and process data,
can be read out from the screen recorder with the aid of the serial
interface. The connection and functionality of the serial interface
are explained in detail in the Interface Description B 95.5010.2.2.

3.2 Connecting configured mTRON modules
The mTRON modules are connected to the screen recorder using a screened
twisted pair. The pre-configured mTRON modules are labelled according to
customer specification.
Example: 1 screen recorder and 2 analogue input modules
In the example shown, two analogue input modules are connected to the
screen recorder in the “line structure”type of connection. The physical ends
(screen recorder and module 2) must be fitted with a termination resistor.
The bus termination resistor (50Ω) of the screen recorder is activated through
a wire link between pin 4 and pin 8 (see Section 3.1 “Connection diagram”).
Further details on the bus termination of the analogue input modules can be
obtained from the installation instructions for the modules.

4 Operation and visualisation
4.1 Instrument info
Two function keys are available in the screen recorder menu Instrument info
that can be used for communication and service purposes.
“Wink”
message
A “Wink”message causes all the connected mTRON modules to flash their
service LEDs for 10 seconds at one second intervals (display “Wink received”
on the operating unit 70.4035). This function enables the identification of
mTRON modules which are not contacted by the screen recorder.
Service The “service-pin message”is only required with simultaneous use of the
JUMO mTRON-iTOOL project design software. Using this function, the posi-
tion of the screen recorder that is connected can be determined within iTOOL
and reported (“joining”).
Wink
Service
HIndependently of the “Wink”function, the service LED of an
mTRON module flashes if a fault occurs in the module. The blink
characteristics of the mTRON module are described in the corre-
sponding installation instructions.

4.2 External analogue inputs
The external analogue inputs which are connected are configured in the
screen recorder menu Configuration ➔Analogue inputs. One of the menu en-
tries “External input 1 —24”or “External counter 1 —2”has to be selected
for this purpose.
After an external input has been selected, its configuration menu will appear
on pressing the Ekey.
Only the parameters “Scaling start”, “Scaling end”and the sub-menu “Addi-
tional parameters”are available here. All other parameters for the mTRON
modules are either pre-configured ex-factory to customer specification, or
have to be altered using the JUMO mTRON-iTOOL project design software.
The parameters which are available are described in detail in the Operating In-
structions B 95.5010.01
Sampling cycle The external analogue inputs are registered by the screen recorder with a max-
imum delay of 1 second.

4 Operation and visualisation
4.3 External logic inputs
The menu Configuration ➔Digital signal name is available for the external log-
ic inputs which are connected.
Ater selecting the menu entry “External input 1 —6”and subsequently press-
ing the Ekey, a character string can be entered that will identify the input.
This identification is shown in different graphical representations on the screen
recorder.
Sampling cycle The external logic inputs are registered by the screen recorder with a maxi-
mum delay of 1 second.
4.4 External counters
The two inputs (external counters 1 —2) are a special feature. They are in-
tended for connection to the counter outputs of two mTRON analogue input
modules. Each counter contains the result of a hardware pulse counter of the
Neuron firmware for two cycles of the mTRON analogue input module (one cy-
cle = 420msec) and has 16 bit (without sign). Up to 65535 pulses in 840msec
can be counted in this way.
The counters are configured via the menu Configuration ➔Operating func-
tions ➔Counters.

5 JUMO mTRON-iTOOL project design software
This chapter contains all the information necessary to establish a connection
between the screen recorder and the mTRON modules, using the
JUMO mTRON-ITOOL project design software .
The data between the screen recorder and the mTRON modules are ex-
changed via LON network variables (NVs) which are “bound”with the aid of
the iTOOL project design software. The same conditions apply (bus transfer
parameters) as for all mTRON modules. For further information, please refer to
the mTRON system manual.
5.1 Establishing a network connection
The setup interface of an mTRON module is used to provide the connection
between the PC (iTOOL) and the mTRON modules. As long as a module is
used for configuration purposes (setup connector plugged-in), it is not active.
All the other mTRON modules continue to operate unchanged during configu-
ration .
5.2 Input network-variables
Values and operating signals from other modules can be transferred to the
screen recorder via the network through the input network-variables.

5.3 Output network-variables
The internal analogue and logic inputs, as well as the two counters of the
screen recorder, can be transferred via the network to other modules, using
the output network-variables. In conjunction with a logic module (70.4030), for
example, eight measurement inputs can thus be logically linked.
