Channel/Relay Types
Type values for channels, relays, communication input, and computation constants.
Can be used to specify the channel or relay.
Mnemonic Description Channel Relay
DAQDA100_CHTYPE_MAINUNIT Expandable model - Yes
main unit.
DAQDA100_CHTYPE_STANDALONE Value representing the Yes Yes
standalone unit. Same as
subunit number of 0.
DAQDA100_CHTYPE_MATHTYPE Value representing the Yes -
computation channel.
DAQDA100_CHTYPE_SWITCH Value representing - Yes
the internal switch.
DAQDA100_CHTYPE_COMMDATA Value representing the - -
communication input.
DAQDA100_CHTYPE_CONSTANT Value representing the - -
computation constant.
DAQDA100_CHTYPE_REPORT Value representing the - -
report.
Yes : Channel/Relay of the type exists.
-
: Channel/Relay of the type does not exist.
Note
The subunit number used to identify the subunit that is connected to the expandable
model is also a type number. The subunit number is an integer value between 0 and
5. See appendix 2.
