IS-Bus
Add-on module
If additional inputs and outputs are needed with more
comprehensive systems, the system regulator can be
expanded with up to four add-on modules. Each of
these modules has its own microprocessor and adds
another 4 inputs and 3 outputs to the system
regulator.
The inputs are programmed both for temperature
sensors (Pt1000) and also for impulse signals from
volume flow meters. The available outputs are two
relay outputs and one output for electronic speed
control.
To keep the amount of connection work down as much as possible both the data exchange between
the system regulator and the add-on modules and also the energy supply of the add-on modules are
via the IS bus.
CAN bus converter
If the system has to be evaluated via a CAN bus, the IS bus of the system
regulator can be connected to a CAN bus with the help of a CAN bus
converter. The current data (all temperatures, radiation, switch statuses of the
outputs, measured amounts of heat, date and time) of the IS bus are
transferred to the CAN bus and can be evaluated there.
9.2
RS 232
The system regulator can be connected with a PC, laptop or modem via the RS232 interface. In this
manner it is possible to read measured data, change parameters or select functions with a computer.
This means there are exactly the same operating options available on the computer as on the system
regulator itself.

PC-Anschluß Stecker
In addition to the operation of the system regulator, previously saved measured data records can also
be easily down loaded onto the computer as an ASCII file. To do this click with the right mouse button
on the “Download records “ box and save the file with “Save target as...“ at the desired location.
For reasons of memory space, only the first two time values (i.e. with day diagrams the time; with
month diagrams the days; with year diagrams the months) are ever indicated with the ASCII files
because their distances are always the same size. To edit the measuring values in Excel, these time
values can be automatically supplemented: select all 96 cells in the corresponding column, go to
“Edit
Æ
Fill
Æ
Series...“; select “AutoFill “ and press “OK”. Excel then fills in all cells correctly.
Attention:
Connecting the controller to a
modem, you have to use a null
modem cable between
connection cable and modem.
