6.1.1. RS485 INTERFACE DIAGNOSTICS
Frame errors counter and parity errors counters are refreshed pressing button Read Counter.
In order to reset the counter from module memory press button Delete Counters.
Frame errors counter - is increased e.g. errors from incorrect speed to actual speed of data transmitted.
Parity error counter – counts errors, which can be from bits corrupted in the transmitted character.
6.1.2. 1-WIRE INTERFACE DIAGNOSTICS
Errors encountered during searching for sensors and errors associated with readout measurements counter are refreshed by pressing
button Read Counter.
To reset the counter in module memory press button Delete Counter.
Errors of searching counter - is increased in case of errors detected from sensor searching process on 1-WIRE network.
Errors of measuring reading counter - is increased in case of detection improper data in process of temperature reading.
6.1.3. ADDITIONAL DIAGNOSTICS OF 1-WIRE BUS
Press button Readout Diagnostics for:
- Short circuits on the network
- The number of detected sensors,
- Network types,
- Correctness’s of communication,
- Detection of 1-WIRE bus converter.
6.1.4. SYSTEM DIAGNOSTICS
It is possible to readout a number of system counters (information about module operation) by pressing the button Read Counters.
Delete the counter in module memory individually of each e.g. Delete WD Counter.
Register counter of WatchDog –the number of restarts of the processor for program WatchDog.
Register counter of Power-On – the number of power cycles of the module.
Register counter of Button – the number of RST (Reset) button.
Register counter of Brown-On – specifies the number of the operating voltage drops below allowable voltage level
After that, can be set the switch section SW1 to RUN mode as in the table below.
SW1-1 SW1-2
OFF OFF
Yellow LED will be OFF.
6.2. DIAGNOSTIC OF MEASUREMENT CHANNELS
After configuration the measurement channels can be carried out their diagnosis and verify communication on 1-Wire bus.
In the purpose of readout measurement channels diagnostic, set micro switch SW1 to configuration mode as shown in the table
below.
SW1-1 SW1-2
ON OFF
Yellow LED will blink with frequency 1 Hz.
Start ADAUtil software and select Configuration => Communication on left panel and on right select COM port used for changing
software. Then select Configuration => Communication => ADA-401WP => Measuring Channels, and on right window press
Readout Configuration form Module. Scroll on right, until to see the unit Diagnostic of channels. On the screen are the columns:
Value - measurement value readout from the sensor.
U.m. - unit of measurement measured by the sensor.
V<VL - indicates that the value readout from the sensor is short then the lower limit of the value VL.
V=>VH - indicates that the value readout from the sensor is equal to the lower limit of the value VH
Enable - indicates that the measurement channel is unblocked and measuring data and the status channel are being
updating systematically.
Assigned - indicates that sensor of serial number was assigned to measuring channel.
Busy - indicates that sensor is processing data.
Detected - indicates that the sensor of serial number from field Sensor SN was detected.
CRC - indicates error of CRC sensor memory or connection error.
