RN200 user manual 17
The
communication
error
counters.
The
instantaneous
counters
of
transmission/reception errors and the maximum values reached by them are
displayed. It is possible to reset the maximum values (and at the same time force the
exit from the BUS-OFF state) by pressing the
ACK/ENTER
and
ESC/SHIFT
buttons
simultaneously for 5 seconds. Since there are two CAN interfaces, you must first
select the desired CAN interface and then reset the counters: to select an interface
press the
ACK/ENTER
key and use the ▲ and ▼ keys.
Internally, RN200 uses a third CAN interface for communication between its microcontrollers.
If necessary, the status of the third interface can also be displayed by activating bit 8 of
parameter P.0495.
These pages are dedicated to the display of the generic states acquired through the digital
inputs, configured with the functions DIF.3201 and DIF.3202 (page 1), DIF.3203 and DIF.3204
(page 2), DIF.3205 and DIF.3206 (page 3).
The page uses one row for each configured input. If more than 9 inputs are configured on each
page, the controller displays them all by rotating them (9 at a time) every two seconds: holding
the
ESC/SHIFT
button stops rotation. If there are no inputs configured on a page, the page is
not displayed.
On each row, the controller shows the text configured for the digital input and the logical status
of the input.
If the DIF.3202, DIF.3204 and DIF.3206 functions are used, when the input is activated, the
controller forces the display of the relative page.
The page
S.11
displays the status of:
The digital inputs of the controller.
The analogue inputs used as digital (dashes are displayed if they are not used as
digital inputs).
Virtual digital inputs.
The page
S.12
is displayed only if DITEL modules have been configured. It displays the status
of the digital inputs acquired by the DITEL modules. If a DITEL module does not communicate
correctly, the controller displays dashes instead of the state of the inputs.
By pressing the
ACK/ENTER
button, the inputs can be shown in three different ways:
LOGICAL STATE
: the controller shows the logic level of the input (active or inactive)
used in the management of the operating sequence.
PHISICAL STATE
: the controller shows the electrical level (active or inactive, or high
or low) actually present on the input; it can be opposite to the corresponding logical
state. It is displayed in REVERSE.
BY FUNCTION
: the controller shows a list of the functions actually associated with
the digital inputs, displaying the logical status (1/0) relating to each function,
regardless of the input actually associated with the functions. If more than 8 functions
are used for the digital inputs, the controller displays them all by rotating them (8 at a
time) every two seconds: holding the
ESC/SHIFT
button stops rotation.
The page
S.13
displays the status of the digital outputs of the controller.
