Modbus communication errors
Code Name Description
0x00 - No error
0x01 Illegal Function The selected function code is not permitted in
the transmitter. Always use Read Input Registers
(0x04) to read measured values.
0x02 Illegal Data Address. The selected start address is not permitted in the
transmitter. Only use the start addresses listed
to read measured values.
12.5 Diagnostics information via dispersion indicator
The dispersion indicates a disturbance in the liquid caused by the dispersion of gas bubbles
or particles. This causes a widening in the group and phase speed of sound.
The measuring device displays a standardized factor. If this value is less than 1, this
indicates that the speed of sound determined for the undisturbed fluid can still be
determined with the specified measured error. On the other hand, the density measured
error can already be greater than the measured error specified under reference conditions
at values over 0.25.
Therefore, if the speed of sound and temperature are used for concentration
measurement, the value of 1 should not be exceeded. If the density is used, the value of
0.25 should not be exceeded.
If the measured dispersion is greater than the configured switch point, the measuring
device does not display the concentration any more. The configured switch point can be
viewed as follows:
Navigation using transmitter with touch screen: "Settings" → "Application parameters" →
"Diagnosis" → "Process disturbance" → "Switch point"
Navigation using the Viewer: menu "Teqwave Transmitter" → "Display filter" → "Process
disturbance" → "Switch point"
