)

Parameters

Name

Type

Comments

nHandle

SHORT

Handle to a GX6377 board.

nRelayType

SHORT

Specifies the type of relay:

0 = GX6377_RELAY_TYPE_HIGH_CURRENT

1 = GX6377_RELAY_TYPE_FORM_A

2 = GX6377_RELAY_TYPE_FORM_C

nChannel

SHORT

Specifies the relay number according to the specified the type of relay as follow:

GX6377_RELAY_TYPE_HIGH_CURRENT: Channels 1-5

GX6377_RELAY_TYPE_FORM_A: Channels 1-4

GX6377_RELAY_TYPE_FORM_C: Channels 1-4

pnState

LPSHORT

Returned relay state. Closed = 1, Open = 0.

pnStatus

LPSHORT

Returned status: 0 on success, negative number on failure.

Comments

Use the

Gx6377RelayGetGroupChannels

to retrieve the status of all channels of the specified relays type.

Example

The following example returns the state of channel 2 for the high current relays type:

SHORT nState;
Gx6377RelayGetChannel (nHandle, GX6377_RELAY_TYPE_HIGH_CURRENT, 2, &nState, &nStatus);
