o
TChangeRelay
typedef struct{
unsigned char relay;
unsigned char state;
} TChangeRelay;
Where relay is the number of the relay to be affected – 1 (For example, 0 for relay 1 and 1 for
relay 2) and state sets the state of the relay (1=Energize; 2=Relax).
o
TChangeRelays
typedef struct{
unsigned char relayStates[32];
}TChangeRelays;
Where relayStates is an array of relay states as defined below:
#define NO_CHANGE 0
#define ENERGIZE 1
#define RELAX 2
This payload is supported by devices that support the DxP protocol with 2-32 controllable
relays.
o
TPulseRelay
typedef struct{
unsigned char relay; //the relay to be pulsed
unsigned char state; //the state to pulse
uint16 pulseWidth;
//the pulse width in seconds
}TPulseRelay;
Where relay is the number of the relay to be affected, state is the state to pulse, and
pulseWidth is the time to pulse in seconds.
