4.3. Operating modes
Independent of the operating states the controller can be
operated in different operating modes. The control bits can be
set and reset via the application software or in test operation
with the programming software ecolog 100
plus
(window:
Global
Variables
).
Test
To get this operating mode apply a high level (supply voltage) to
the test input. In the RUN or STOP mode the controller can now
accept commands via one of the interfaces. The state of the
user program can be queried via the flag TEST.
Serial Mode
The serial interface is available for a data exchange in the
application. Debugging of the application software is only
possible via the CAN interface.
This function is switched off as a default (FALSE). The state of
the user program or the programming system can be controlled
and queried via the flag SERIAL_MODE.
ISO Direction
This function switches between Send data and Receive data
when the ISO 9141 interface is used..
TRUE Send data
FALSE Receive data (standard setting)
The flag ISO_DIRECTION is used to switch the ISO 9141
diagnostic interface between ´Send data´ and ´Receive data´.
The ISO interface is a special form of a serial interface that
provides communication with the diagnostic interfaces in the
vehicle.
The use of the ISO interface requires hardware and software
adaptations which are not included in the standard units.
When the ISO interface is used the serial interface is not
available for program download and debugging. Program
download and debugging are
only
possible via the
CAN
interface
.
The function is only available when the test input is 'open'.
