Standard Input Variables:
Variable Type Description
Stage Read / Write The last measured stage value is returned. (Only available on the
H-350XL and the H-510XL)
RemStage Read / Write The last measured value for the remote stage variable is returned.
LastStage Read / Write The stage value measured on the previous scan will be returned. Only
available on the H-350).
PtTemp Read / Write The last measured PtTemp value is returned. (Only on the H-350XL)
PSI Read / Write The last measured PSI value is returned. (Only on the H-350XL)
AnaX Read / Write The last measured value for analog channel X (X = 1 to 4) is returned.
Freq Read / Write The last measured freq value is returned.
Digio1 Read / Write The last measured input state for digital channel 1 is returned.
Digio2 Read / Write The last measured input state for digital channel 2 is returned.
Counts Read / Write The last measured count value is returned.
Totcnt Read / Write The last measured total count value is returned.
Countrate Read / Write The current count rate on the counter input.
Encodr Read / Write The last measured encoder input value is returned.
Tscans Read / Write The total scans value is returned.
SdiAP Read / Write The last measured value for the selected SDI-12 variable is returned
A = address 0 to 9, P = parameter 1 to 9
FntXX Read / Write The last calculated value for function XX is returned. (XX = 01 to 40)
BasicX Read / Write The value of one program can be used in other programs. (X = 1 to 5)
Note: Standard input variables are normally read only but may also be assigned a new value
directly in the XL-BASIC program regardless of the variables corresponding hardware
input condition. Be aware that based on system configuration the input variable could be
updated by the system after the variable was set by the XL BASIC program. Writing to
these variables should be avoided or only used in advanced applications. For example, in
the following segment of code, the second line makes the first line useless.
measure(ana1) measurement analog input 1 now and update its variable.
ana1 = 12.34 Sets variable ana1 to 12.34 regardless of the voltage on analog 1.
