4.5 Zero Crossing and Relay Control
4.5.1 MAPI_RelayConfig()
Purpose Read/Write relay configuration values. Relay configuration is applicable to all
channels/outlets.
Synopsis void MAPI_RelayControl( IN Bool Operation, OUT/IN struct
Relay_Config_t Relay_Config);
Where Relay_Config_t is defined as:
struct Relay_Config_t
{
Unsigned Char Relay_CTL;
Unsigned Integer SeqDlyTime;
Unsigned Integer DeEnergizedTime;
Unsigned Integer EnergizedTime;
Unsigned Char InvertPNonLatch;
};
Parameters Operation Input parameter.
TRUE (1) = set operation. FALSE (0) = get operation,
Relay_Config will all be output parameter.
When Operation = TRUE:
Relay_CTL Output parameter.
This parameter is output only. It is set via
MAPI_RelayControl().
SeqDlyTime Input parameter.
Set the new Sequence Delay Time in 10ms
units. Delay time is time between turning
Relays ON (close circuit). Default value is 10
100ms.
DeEngergizedTime Input parameter.
Time in mseconds + 1msecond to delay after
open circuit.
EngergizedTime Input parameter.
Time in msecond + 1msecond to delay after
close circuit.
InvertPolarity Input parameter.
Bit 1 = Polarity (0 = non-inverted). Bit 0 =
Latch type (0 = non-latched).
Notes:
Sequence Delay Time will be used between turning relays ON.
Energized Delay Time is used as the delay time to wait
immediately after a zero-crossing before close circuit.
DeEnergized Delay Time is used as delay time to wait
immediately after a zero-crossing before open circuit.
Return Codes None.
