DISPLAYING
THE
PROGRAM
VERSION
AND
CHECK
SUMS
(P05)
This
function
shows
the
number
of
the
program
version
of
the
dispenser
counter
and
different
check
sums.
These
values
are
intended
for
metrology
authorities
and
authorized
service
engineers.
The
meaning
of
the
individual
parameters
is
described
in
the
table
below.
Parameter
Meaning
P05
‐
1
Version
of
the
metrologically
relevant
part
of
the
program.
It
is
specified
in
the
type
certificate
(e.g.,
102
=
version
V1.02)
P05
‐
2
CRC
(check
sum)
of
metrologically
relevant
part
of
the
program.
It
is
specified
in
the
type
certificate
(e.g.,
dbd2
FFA4)

and
release
of
the
whole
program
(e.g.,

release
14)
P05

CRC
(check
sum)
of
the
whole
program
(e.g.,
27E6

P05
‐
5
CRC
(check
sum)
of
the
temperature
sensors
unit
PDEINP1
program
(for
temp.
sensors
1
to
4).
If
not
present
„

CRC
(check
sum)
of
the
temperature
sensors
unit
PDEINP1
program
(for
temp.
sensors
5
to
8).
If
not
present
„

Date
and
time
the
program
compilation.
The
first
line
shows
the
time
(hhmmss)
and
the
second
the
date
(DDMMYY).
P05
‐

CRC
of
the
program
of
the
pressure
sensors
unit
PDEDPS
with
address
1.
If
not
present,
"

P05
‐

CRC
of
the
program
of
the
pressure
sensors
unit
PDEDPS
with
address

If
not

P05
‐

CRC
of
the
program
of
the
pressure
sensors
unit
PDEDPS
with
address

If
not
present,
"

P05
‐
11
CRC
of
the
program
of
the
pressure

unit
PDEDPS
with

4.
If
not
present,
"

is
displayed
NOTE
Metrologically
relevant
data
P05
‐
1
and
P05
‐
2
also
appear
on
the
display
for
a
while
after
the
power
on.
NOTE
The
calculated
CRC
(cyclic
redundancy
sum)
values
from
sub
‐
parameters
1
and
3
are
checked
after
switching
on.
If
the
calculated
checksum
is
different
from
the
stored
correct
sum,
the
dispenser
is
blocked
and
error
message
E13
is
displayed.
Higher
cyclic
checksum
orders
are
displayed
on
the
amount
line,
lower
orders
on
the
quantity
line.
The
CRC
of
the
peripheral
unit
programs
(PDEINP
and
PDEDPS)
is
checked
before
each
delivery
is
enabled.
If
the
calculated
value
of
the
peripheral
unit
checksum
does
not
match
the
correct
value,
delivery
(fuelling,
pumping)
is
not
started
and
the
corresponding
error
message
is
displayed.

MODBUS
INTERFACE
ACTIVATION
(P06)
The
modbus
interface
(diagnostic

the
Modbus
interface
by
entering
a
valid
