Sets the Block Number (9971=Write Module’s Time) and then increments the
output sequence number (OutputControl[1]) by one. Once the module reads a
new output sequence number from the processor it will process this request. So
remember that the actual trigger is moving a new output block sequence number
value to the module. Moving the block number (9970) is not the trigger to request
this task from the module. MyTrigger is set to -1 as an indication that the logic is
waiting for the response from the module.
IF (MyTrigger=9971) THEN
OutputControl1[1] :=MyTrigger;
OutputControl1[2] :=SetTime.MyYear;
OutputControl1[3] :=SetTime.MyMonth;
OutputControl1[4] :=SetTime.MyDay;
OutputControl1[5] :=SetTime.MyHour;
OutputControl1[6] :=SetTime.MyMinute;
OutputControl1[7] :=SetTime.MySecond;
OutputControl1[8] :=SetTime.MyMillisecond;
Temp:=WORD_TO_INT(OutputControl1[0]);
Temp:=Temp+1;
OutputControl1[0]:=INT_TO_WORD(Temp);
END_IF;
Once the request was processed the module will send the block response and
increment the received output sequence number by 1. So the output sequence
number is one less than the input sequence number the module has sent a new
block. *).
5.3.2 Read Status (Block 9250)
