Data Type CompactLogix 5370
Data Type Controller Tag Address
(Global) Example Controller Tag Address
(Local, MainProgram) Example
Boolean BOOL Tag1 Program: MainProgram.Tag1
32-bit integer DINT Tag2 Program: MainProgram.Tag2
16-bit integer INT Tag3 Program: MainProgram.Tag3
8-bit integer SINT Tag4 Program: MainProgram.Tag4
Real REAL Tag5 Program: MainProgram.Tag5
String STRING

(1) Tag6.Data/N – N is the length of String.
(2) Program: MainProgram.Tag6.Data/N
Note the following:
• Tag address of Tag6.Len can be read/written for the length of String.
• Tag address of Tag6.Data[characterNo] is to read/write individual character of string by ASCII. For example, Tag6.Data[1] refers to the element 1.
