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 modules 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.
2 General
H
H
The 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 detail when ordering his measuring system.
The recorder can also operate without internal (built-in) analog
channels. In this case, the measurements are obtained exclusively
from the mTRON modules.

3 Connecting the interface
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 recorder 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 obtained from the installation instructions for the modules.

Line structure
Ring structure
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).
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”
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.

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 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 configuration.
The setup interface of the recorder can not be used for this purpo-
A
se; it is reserved for the setup program.
5.2 Input network-variables
Values and operating signals from other modules can be transferred to the recorder via the network through the input network-variables.

5.5 mTRON modules
All available mTRON modules can be linked to the recorder.
5.5.1 mTRON operating unit
If an mTRON operating unit is connected to the LON network, it can be used
to read all the network variables (except the input counter) at the “current module data” level.
5.5.2 Communications module
The communications module enables remote monitoring of the recorder and
the mTRON modules. The addresses required for establishing a connection to
the recorder using the communications module are described in the “JUMO
mTRON communications module” system manual. All the network variables
(except the input counter) of the recorder can be addressed.

5.6 Project design example
The JUMO mTRON-iTOOL project design software must be used if no configured mTRON modules are available, or if these have to be reconfigured.
When operating the software it is essential to follow a defined path.
- Selection of the software module from the module library
- Configuration of the mTRON modules
- Binding of the input and output network variables
- Transfer of project to the modules (download)
Selection of
the software
modules
The modules available in the module library can be dragged into the working
area by keeping the left mouse button pressed down (drag & drop). Each module can subsequently have a name assigned.
23
5 JUMO mTRON-iTOOL project design software
Configuring the
mTRON
modules
In order to connect a temperature probe to an mTRON module, this module
has to be configured.
This is done by clicking on the button with the left mouse button. A dialog
window appears in which first the entry Analog input (1) is selected, and then
the function (2) is called up.
In the dialog window which now opens, the required input can be configured.
Confirm the entry by pressing the key.
24
5 JUMO mTRON-iTOOL project design software
Binding the
networkvariables
After the analog inputs have been successfully configured, the software inputs
and outputs are selected. To do this, it is necessary to change to the “bindings” level.
Afterwards all available inputs/outputs are made visible on the screen using
the buttons (analog input) and (LOGOSCREEN).
The bindings between input and output are made with the mouse (keep left
mouse button pressed down). The binding can be identified by a name which
can be selected.
H
There are bindings that are not permitted (prohibition sign appears). It comes up, for instance, when an attempt is made to link
analog network variables to logic ones.
25

Transferring the
project
The following steps have to be carried out before all settings can be transferred from the project design software to the recorder and the mTRON modules.
1. The button is used to establish the on-line connection to the modules.
2. Using the button, all modules that are physically available are
entered within the project design software.
3. The button is used to assign the modules that are physically
available to the software modules.
The project can now be transferred to the modules. The menu Network is
available for this purpose.
A check has first to be carried out using the function Network r Compile. Only
when the check has been successfully completed, can the project be transferred to the individual modules with the aid of the Network r Download
function.
26
6.1 Response after a power failure
After the supply voltage has been restored and the subsequent initialization
phase completed, all network-variables are reset to the correct values. The input and output counters continue to operate with the values present at the
time of the power interruption.
6.2 Response on failure of mTRON module
When the recorder recognizes the failure of an mTRON module (within a maximum of 20 seconds after the failure) which provides values for its input network-variables, it triggers the “Error” event. Measurements are designated
“no measurement” (display “-------”), counters are assigned the value 0 and
logic inputs the value FALSE. In addition, the info symbol flashes and in the
menu Device info
Within a maximum of 10 seconds after rectifying the error, the alarm should
cease to be present within the recorder and the exchange of data should function again.
mTRON modules which have failed can only be recognized if there
H
is at least one network-variable binding between them and the recorder.
