National Instruments 320682C GetChannelIndices

Chapter 10 Easy I/O for DAQ Library

initialHighLimitVolts specifies the maximum voltage that is measured for all channels in the

channel string listed before a command string that specifies a new high limit. For the following

channel string:

"0,1; cmd hi 10.0 low -10.0; 2,3"

If initialHighLimitVolts is 5.0, channels "0" and "1" have a high limit of 5.0 and channels

"2" and "3" have a high limit of 10.0.

initialLowLimitVolts is the minimum voltage that is measured for all channels in the channel

string listed before a command string that specifies a new low limit. For the following channel

string:

"0,1; cmd hi 10.0 low -10.0; 2,3"

If the initialLowLimitVolts is -5.0, channels "0" and "1" have a low limit of -5.0 and channels

"2" and "3" have a low limit of -10.0.

GetChannelIndices

short error = GetChannelIndices (short device, char channelString[],

char channelSubString[], short channelType,

long channelIndices[]);

Purpose

Determines the indices of the channels in the channelSubString. For example, if the

channelString is

"1:6"

and the channelSubString is

"1,3,6"

the channelIndices array would be filled as follows:

channelIndices[0] = 0;

channelIndices[1] = 2;

channelIndices[2] = 5;

This function is useful if you want to verify that a particular channel is part of the

channelString.
