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.

network variables
Transfer rate All “bound” network variables are transferred within a maximum of one
second.

The setup interface of the recorder can not be used for this purpo-
se; it is reserved for the setup program.
