The settings of the analog outputs only come into effect if, following the Customer’s orders,
the relative D/A converters have been installed. In the absence of such converters,
command “D” has no effect on the transducer functionality.
14.3.3. COMMAND
“L”
The command “L” allows to
set a numerical value
of the ZERO and FULL SCALE
references of the two cursors, expressing them in millimetres (
or other mechanical units
) in
order to obtain a displacement or level measurement for the digital data (RS485),
expressed in mechanical units.
The command format must be like the one described in the examples, where “L” is
followed by the cursor number (0 or 1) to which the intended setting refers. This is then
followed by “L” if you wish to set the ZERO value or “H” if you wish to set the FULL SCALE
value.
The command subject must be a number composed of 6 positive figures (without signs).
Should two cursors be used on the same measuring probe, cursor “0” refers to the one
nearest the electronics (connector or cable output) while the cursor “1” refers to the
furthest one (see figure 13).
IMPORTANT NOTE: after entering the new parameters, in order for them to have effect, it
is necessary to switch the transducer off and then switch it on again. In this way the
internal coefficients can be recalculated.
Example 1
: @ 0 L0L
000000
<cr>
The lower reference ( ZERO ) of
cursor 0
is set at a value of 0 (mm).
Example 2
: @ 0 L0H
001300
<cr>
The higher reference ( FULL SCALE) of
cursor 0
is set at a value of 1300 (mm).
Example 3
: @ 0 L1L
000100
<cr>
The lower reference ( ZERO ) of
cursor 1
is set at a value of 100 (mm).
Example 4
: @ 0 L1H
001500
<cr>
The higher reference ( FULL SCALE) of
cursor 1
is set at a value of 1500 (mm).
14.3.4. COMMAND
“R”
Command “R” requests, from remote computer or PLC, the
measured value
for cursors 0
and 1.
The subject command “R” is an ASCII character which can take on the following values:
“R0” when you request the transducer for the first cursor value (cursor 0, near electronics).
Example 1
: @
0 R 0 <cr>
“R1” when you request the transducer for the second cursor value (cursor 1).
Example 2
: @
0 R 1 <cr>
14.3.5. COMMAND
“V”
Command “V” requests revision of
firmware
installed into transducer.
Example
: @ 0
V
