5.2.3. 1-WIRE CONFIGURATION
Section
1-WIRE bus
has options
:
–
Baud rate
: standard (at the moment available is standard baud rate),
–
Number of groups in searching process
:
readout only,
–
List of available group of 1-WIRE sensor/systems in searching process
(readout only).
5.2.4. MEASUREMENT CONFIGURATION
Section
Measurement configuration
has options:
–
Measuring data format:
integral number with 2-byte (readout only),
–
Pause between readout:
interval between another readout of measurement from connected sensors - range 1 – 255 sec.
–
Enable single reading sensors:
enable this option causes that each sensor is readout separately. The time of readout one sensor
is about 1 sec.
The effect of this option is:
- extension measurement readout time from sensors,
- reducing current value, being in VDD line or DQ, to current value one sensor in time of measurement processing. It is imported in
potentially explosive environments, after connection an intrinsically safe barrier to ADA-401WP.
–
Enable write TL and TH registers for DS18xxx:
enable this option causes that change of Lo and Hi values in the configuration on
measurement channel is write in TL and TH registers of DS18xxx sensor and readout from these registers. Disable this option
causes that Lo and Hi values setted in the measurement channel configuration are written to ADA-401WP memory and readout
from there.
Options
Enable single reading sensors
and
Enable write TL and TH registers for DS18xxx
are available from 2,005 firmware
version and 1.7.1.0 version of ADAUtil.
5.2.5. AUTOMATIC ASSIGN SENSORS TO MEASUREMENT CHANNELS (AAS) CONFIGURATION
AAS function lets quickly assign sensors to measuring channels in the order specified by their heating temperature AAS. Description
of using the AAS function is described in point
CHANGING SENSORS ORDER BY THE USE OF AAS PROCEDURE
Configuration of
AAS function :
-
Enable Automatic Assign Temperature Sensor to Measure Channel
: enable or disable module AAS function,
-
Temperature AAS
:
0 – 50 °C, - setting of AAS temperature above followed by automatic assignment of the sensor to a channel.
After configuration press button
Save configuration to module
.
Set SW1 switch section to run mode as in the table below.
SW1-1
SW1-2
OFF
OFF
Yellow LED will be OFF.
5.3. MEASURING CHANNEL CONFIGURATION
Set the SW1 micro switch in the configuration mode as table below
SW1-1
SW1-2
ON
OFF
Yellow LED will blink with frequency 1 Hz.
5.3.1. SENSOR ADDING
After connecting sensors to ADA-401WP, according to point
CONNECTION TEMPERATURE SENSORS
and running
ADAUtil
software
, select branch
Configuration=>Communication
on left panel, and on right select COM port used for module configuration.
Then on left panel select branch
Configuration
=>
Communication
=>ADA-401WP=>Measure channels
and on right will open
[Measure channels configuration and diagnostic]
and press [
Read Configuration form Module] –
readout the configuration of
measurement channels from ADA-401WP.
