◆ bps
| int daq_channel_::bps |
Bytes per sample
◆ chNum
| int daq_channel_::chNum |
channel number.
◆ data_type
| daq_data_t daq_channel_::data_type |
Sample data type
◆ name
| char daq_channel_::name[MAX_LONG_CHANNEL_NAME_LENGTH+1] |
Channel name as a null-terminated character string.
◆ rate
| double daq_channel_::rate |
Sample rate. The NDS1 protocol had an integer rate which is not consistent with minute trend requests.
◆ s
| signal_conv_t daq_channel_::s |
Conversion to engineering units.
◆ tpnum
| int daq_channel_::tpnum |
Test point number; 0 for normal channels
◆ type
| enum chantype daq_channel_::type |
Channel type code. This field replace the group number used in the NDS1 protocol. It resolves cases where there are different channels with the same name, or where a single named channel may several sources. See the chantype enum for more details.
