Case 1 If the instruction is used to receive one message or constantly receive multiple messages by
setting the value of
DataSaveMode to 0, Busy and Active both change to TRUE when Execute
changes from FALSE to TRUE. Done changes to TRUE and both Busy and Active change to
FALSE when a piece of data receiving is finished or the total length of spliced data reaches or
exceeds the set length.
Done changes to FALSE when Execute changes from TRUE to FALSE.
Case 2 If the value of DataSaveMode is set to 1, Busy and Active change to TRUE as Execute changes
from FALSE to TRUE. And the state of Busy and Active both keep unchanged and the instruction
keep receiving data as Execute changes from TRUE to FALSE.
Case 3 Execute is set from FALSE to TRUE again after case 2 and the output state of the instruction
keeps unchanged. Set Abort from FALSE to TRUE. One cycle later, Aborted changes from
FALSE to TRUE and meanwhile Busy and Active change to FALSE. When Abort changes from
TRUE to FALSE, the output of the instruction keeps unchanged. When Execute changes from
TRUE to FALSE, Aborted changes to FALSE.
Case 4 When Execute changes from FALSE to TRUE, Busy and Active change to TRUE. When an
error occurs, Error changes to TRUE, ErrorID shows corresponding error code and meanwhile
Busy and Active change to FALSE. When Execute changes from TRUE to FALSE, Error
changes to FALSE and the value of ErrorID changes to 0.
