Tango::DEV_STRING |
Device name of the PLC Server |
| DBNumber |
Tango::DEV_LONG |
Device representative DataBlock number |
| InputOffset |
Tango::DEV_LONG |
Input offset of the beginning of the data in the DB |
| InputLength |
Tango::DEV_SHORT |
Input length of the data in the DB |
| OutputOffset |
Tango::DEV_LONG |
Output offset of the beginning of the data in the DB |
| OutputLength |
Tango::DEV_SHORT |
Output length of the data in the DB |
| HardwarePollingTime |
Tango::DEV_LONG |
variables will be refreshed by hardware reading
every HardwarePollingTime.
given in : 1/10 sec.
example : 34 sec gives 3.4 sec between hardware reading accesses
Default : 10 ( 1 second |
| ConversionFactor |
Tango::DEV_DOUBLE |
User's conversion factor.
The physical signal range is expected to be 0-MaxVoltage (10V Max)
This signal correspond to an internal value between 0 - 27648
An the user value between 0 - Max range
So the conversion factor should be equal to:
(Max range*10)/(27648*MaxVoltage)

| Formula |
Tango::DEV_STRING |
formule de conversion de la valeur analogique renvoy�e par le PLC en pression
doit respecter la syntaxe muParser
voir http://muparser.sourceforge.net/
La variable ( la valeur brute ) doit �tre repr�sent�e par x dans la formule
ex : x*10^-4 + 27.3 |
| ReciprocalFormula |
Tango::DEV_STRING |
reciprocal function of Formula used to convert physical values to raw values
eg : to write alarm setpoints in the analog gauge controller
voir http://muparser.sourceforge.net/
La variable ( la valeur brute ) doit �tre repr�sent�e par x dans la formule
ex : x*10^-4 + 27.3 |
