Addressing Structure Data Types
Only the atomic structure members can be addressed at the structure level. For more information, refer to the
examples below.
Logix Tag
MyTimer @ TIMER
Client/Server Tag
1. Invalid
TimerTag address = MyTimer
TimerTag data type = ??
2. Valid
TimerTag address = MyTimer.ACC
TimerTag data type = DWord
Addressing STRING Data Type
STRING is a pre-defined Logix data type whose structure contains two members: DATA and LEN. DATA is an
array of SINTs and stores the characters of the STRING. LEN is a DINT and represents the number of characters
in DATA to display to a client.
Because LEN and DATA are atomic members, they must be referenced independently from a client/server. The
syntax is as shown below.
