Applies To

GX5961, GX5964

Purpose

Returns the connection state of the specified channel to the Front Panel Analog I/O Connector.

Syntax

GtDio6xChannelGetAnalogConnection (nHandle, nChannel, pbAnalogConnectState, pnStatus)

Parameters

Name
Type
Comments
nHandle
SHORT
Session identifier:

●     Board handle is used when communicating with the hardware. The Board handle session identifier is returned by calling GtDio6xInitialize or GtDio6xSetupInitialization.

nChannel
SHORT
Used to specify the channel to Get. This parameter is 0-based and refers to any channel in the Domain.
GX5961: Auxiliary channel numbers begin with 1000.
GX5964: Does not have Auxiliary channel).
pbAnalogConnectState
PBOOL
Used to return the channel connection state:

0.     GTDIO6X_CONNECT_OFF: Disable the channel to the Front Panel Analog I/O Connector (J6).

1.     GTDIO6X_CONNECT_ON: Enable the channel to the Front Panel Analog I/O Connector (J6).
pnStatus
PSHORT
Returned status: 0 on success, negative value on failure.

Comments

This function returns the state of the channel isolation relay to the Front Panel Analog I/O Connector. The channel connection can either be enabled or disabled per channel. This function addresses any channel in the domain.

Example

The following example connect channels 0 and 6 to the Front Panel Analog I/O Connector, and gets channel 0 connection state:

 

SHORT nStatus;

LONG alChannelList[2];

BOOL bConnectState;

 

// Fill the channels array

alChannelList[0]=0;

alChannelList[1]=6;

 

GtDio6xChannelSetAnalogConnection (nHandle, 2, alChanneList GTDIO6X_CONNECT_ON, &nStatus);

GtDio6xChannelGetAnalogConnection (nHandle, 0, &bConnectState, &nStatus);

if(bConnectState)

   printf(“Channel 0 is connected”);
