Channel/Relay types
Type values for channels, relays, communication input, and computation constants.
Can be used to specify the channel or relay. Definitions consisting of a single
character are available also to simplify the statements.
Mnemonic Char Description Channel Relay
DAQDARWIN_CHTYPE_MAINUNIT I Value representing the - Yes
main unit expandable model
DAQDARWIN_CHTYPE_STANDALONE Value representing the Yes Yes
model of the standalone unit.
Same as subunit number
of 0.
DAQDARWIN_CHTYPE_MATHTYPE A Value representing the Yes -
computation channel.
DAQDARWIN_CHTYPE_SWITCH S Value representing the - Yes
internal switch.
DAQDARWIN_CHTYPE_COMMDATA C Value representing the - -
communication input.
DAQDARWIN_CHTYPE_CONSTANT K Value representing the - -
computation constant.
DAQDARWIN_CHTYPE_REPORT R 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.
