nHandle |
SHORT |
Handle to a GX6315 board. |
nRelayType |
SHORT |
Specifies the type of relay 0 or 1:0 for the high current relay,1 for the relay driver. |
nChannel |
SHORT |
Specifies the relay number. Can be 1-45 for the high current relay, 1-9 for the driver relay. |
pnStatus |
LPSHORT |
Returned status: 0 on success, negative number on failure. |
The Gx6315GetChannel function can be used to retrieve the current channel state.

Caution - When closing a relay, verify that all other relays on the same circuit that may cause a short are disconnected (a delay may be required between switching commands). Low Impedance sources such as power supplies may cause irreversible damage to this product when shorted to other signals. |
The following example closes relay 1 and relay driver 2:
Gx6315Close(nHandle, 0, 1, &nStatus);
Gx6315Close(nHandle, 1, 2, &nStatus);
Gx6315Initialize, Gx6315Open, Gx6315SetGroupChannels, Gx6315GetChannel.
