12.6.5.4 Modify the Function Block
Secondly you need to modify the function block FB_Trispector_Test to parse the incoming
data correct. Open the function block and scroll down to the comment:
//********************START THE PARSING*********************
This is where the parsing of the string into different data types starts. Since the func‐
tion block expects four values (string;real;int;char) this parsing is divided into four sec‐
tions:
//1: String of unknown size
************************************************************
WHILE (BYTE_TO_CHAR(#arrData[#i]) <> ';' & #i <>
(#iReceivedLength-1)) DO
#s_temp := CONCAT(IN1 := #s_temp, IN2 :=
CHAR_TO_STRING(BYTE_TO_CHAR(#arrData[#i])));
#i := #i + 1;
END_WHILE;
#Data.StringValue := #s_temp;
#s_temp := '';
#i := #i + 1;
//**********************************************************
//2: Real of unknown size
************************************************************
WHILE (BYTE_TO_CHAR(#arrData[#i]) <> ';' & #i <>
(#iReceivedLength-1)) DO
#s_temp := CONCAT(IN1 := #s_temp, IN2 :=
CHAR_TO_STRING(BYTE_TO_CHAR(#arrData[#i])));
#i := #i + 1;
END_WHILE;
#Data.RealValue := STRING_TO_REAL(#s_temp);
#s_temp := '';
#i := #i + 1;
