Function Documentation

ER GooseTask

(

SINT32

exinf

)

The Goose Task.

This function is the 'Main' function of the Goose Task. The task will enter a 'while(1)' loop and not exit unless an error occurs. Two function are performed by this task:

1. Send the defined GOOSE data set (Goose 1) at the specified intervals.
2. Receive the defined GOOSE data set (Goose 3) and import the sent value into the IED. A single boolen value is sent and this value is used to modify the data used in GOOSE data set 2 (Goose 2). The data set consists of an array of 64 boolean values. The Sequence number of the received packet is used as an index into this array and the boolean value found at this location is set to the value in the received packet.

First Packet (SeQ 0)

Goose 2	0	1	2	3	4	5	6	7	8	9	10	11	12	..	63
Array of BOOL	T	F	F	F	F	F	F	F	F	F	F	F	F	F	F

Second Packet (SeQ 1)

Goose 2	0	1	2	3	4	5	6	7	8	9	10	11	12	..	63
Array of BOOL	T	T	F	F	F	F	F	F	F	F	F	F	F	F	F

Third Packet (SeQ 2)

Goose 2	0	1	2	3	4	5	6	7	8	9	10	11	12	..	63
Array of BOOL	T	T	T	F	F	F	F	F	F	F	F	F	F	F	F

Once the value has been updated, a GOOSE packet (Goose 3) will be sent out with the updated values.

Precondition

static void SendGoosePacket ( const UINT8  u8_SrcPort, const UIED_INDEX  idx_GooseIndex  )

static

Sends a Goose packet out of the specified port.

This function is used to the build a specified GOOSE packet and send it out of the specified port.

u8_SrcPort	Physical Port Number
0	Port P0
1	Port P1
2	Both (Ports P0 & P1)

Precondition

None.

Postcondition

A Goose packet will have been created and sent

Parameters

u8_SrcPort	The port number to send the packet out of
idx_GooseIndex	The index of the Goose packet definition to be sent

Returns

None
