Get_Value; Get_Values - Scanlab RTC6 PCIe Board Installation And Operation Manual

Ctrl Command get_values
Function Returns the current values of up to 4 specified signals.
get_values( SignalPtr, ResultPtr )
Call
SignalPtr
Parameters
ResultPtr
Comments • Up to 4 desired signals can be simultaneously queried. The selectable signal types are
identical to those of
range, signal types and other information). The to-be-outputted signal types must be
specified by SignalPtr. The corresponding signal values are then stored by ResultPtr.
For storage of each queried data set, the user program must make available (at the
address specified by ResultPtr) 4 × 4 bytes of PC memory.
• get_values functions similarly to
0 and performs no query on channels for which an invalid signal type has been
specified by SignalPtr. A

• If any of the pointer parameters are NULL, then get_values is not executed and a
