N ote :
W hen transmitting the PC / DCS value in M odbus - TCP protocol
( measured value fi ling as
2
byte short ), the decimal point is not
transmitted , the value - 0 , 5 bar is transmitted as - 50 . I f the data
format was selected in such a way that values outside the
value range can be caused
, limitation to the highest value of
the value range is made .
E
xample
: P
ercent was selected as "
R
eference value " and
# .
###
as " D ata format " . W ith this setting , the value
100
% should
be transmitted as 100000 which is outside the valid range of
max . +
32767
. T his means that a limit will be imposed and
32767 transmitted instead . T o avoid this ,
"

"
# . ##
should be chosen so that the value
100
% is transmitted as
10000
.
N ote :
W ith the switching inputs of PLICSRADIO
®
C
62
( measure -
ment loops 4 … 6 ) the value 0 ( switch open ) and 100 ( switch
closed ) are transmitted as measured values , the units are
deleted .
T he switching conditions of the relay are transferred as bit
information .
T he following equivalencies apply to the switching relays :
l
0
= S witching status O ff
l
1
= S witching status O n
T he following equivalencies apply to the fail safe relay :
l
0
= F ailure message O ff , relay switching condition O n
l

=
