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 functionality of the
paperless recorder.
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 recorder :
- Paperless recorder with LON interface
- 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. A setup interface is required for connecting mTRON modules
to a PC.
HThe JUMO mTRON-iTOOL project design software can only be
dispensed with if the mTRON modules have been configured by
JUMO GmbH & Co. KG prior to delivery. In order for this to happen,
the customer must have specified the required configuration in de-
tail when ordering his measuring system.
HThe recorder can also operate without internal (built-in) analog
channels. In this case, the measurements are obtained exclusively
from the mTRON modules.

2.3 Identifying the interface
The LON interface is available as an extra. The contents of the menu
Device info rInterface show whether it is implemented in the system.
If the entry Device info rInterface 21 is set to “ExtExpansion”, the LON inter-
face is available.

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 device and process data, can
be read out from the recorder with the aid of the serial interface.
The connection and functionality of the serial interface are ex-
plained in detail in the Interface Description B 70.6570.2.0.

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

3 Connecting the interface
A screened twisted pair is used as a transmission line. The connection can be
made as a line, ring, star or mixed structure (free topology).
Line structure
Each physical end is provided with a termination resistance of 100Ω, which is
activated by a switch on the module.
Chapter 3.3 “Setting the LON termination resistance”
Ring structure
In this wiring arrangement, the network remains functional even when there is
an interruption. The termination resistance of any module in the ring must be
set to 50Ω.
Chapter 3.3 “Setting the LON termination resistance”

Star structure
The termination resistance of any module in the star must be set to 50Ω.
Chapter 3.3 “Setting the LON termination resistance”
Mixed
structure
The termination resistance of any module must be set to 50Ω.

4 Operation and visualization
4.1 Device info
Two function keys are available in the recorder menu Device info, which 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 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 recorder that is connected can be determined within iTOOL and re-
ported (“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 analog inputs
The external analog inputs which are connected are configured in the recorder
menu Configuration ➔Analog inputs. One of the menu entries “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 key.
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 70.6570.0
Sampling cycle The external analog inputs are registered by the recorder with a maximum de-
lay of 1 second.

4 Operation and visualization
4.3 External logic inputs
The menu Configuration ➔Digital signal name is available for the external log-
ic inputs that are connected.
Ater selecting the menu entry “External input 1 — 6” and subsequently press-
ing the key, a character string can be entered that will identify the input.
This identification is shown in different graphical representations on the re-
corder.
Sampling cycle The external logic inputs are registered by the recorder with a maximum 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 analog input
modules. Each counter contains the result of a hardware pulse counter of the
Neuron firmware for two cycles of the mTRON analog input module (one cycle
= 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 ➔Control functions
➔Counters.

5 JUMO mTRON-iTOOL project design software
This chapter contains all the information necessary to establish a connection
between the paperless recorder and the mTRON modules, using the
JUMO mTRON-ITOOL project design software.
The data between the recorder and the mTRON modules are exchanged via
LON network variables (NVs) which are “bound” with the aid of the iTOOL pro-
ject 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 re-
corder via the network through the input network-variables.

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