int MSXExxxx__DigitalIOTestOutputsPowerSupply ( xsd__unsignedLong  ulPort,
xsd__unsignedLong  ulOption1,
struct MSXExxxx__unsignedLongResponse Response 
)

Reads the current power supply status of the selected port.
The digital outputs need an external power supply. This function checks the state of the power supply.

Parameters:
[in] ulPort Selected digital I/O port (0 to MSXExxxx__DigitalIOGetNumberOfPorts)
Please read the documentation of the MSXExxxx__DigitalIOGetNumberOfPorts for the description of a port.
[in] ulOption1 Reserved. Set to 0
[out] Response 
sResponse.iReturnValue

  • 0: The remote function performed OK
  • -1: System error occurred
  • -2: The PLD is not working
  • -3: The ulPort parameter is wrong
  • -100: Internal system error occurred. See value of syserrno

sResponse.syserrno system error code (the value of the libc "errno" code)
ulValue Current digital I/O power supply state. Each bit indicates the power supply state of the output. Example:

  • 1: No external supply voltage for the output 0
  • 3: No external supply voltage for the outputs 0 and 1
Return values:
0 SOAP_OK
