Chapter 6 Define a tag component
132 Rockwell Automation Publication 1756-RM084S-EN-P - March 2015
• Base tags and aliases can be defined out of order within a tag block.
• You cannot define a second dimension without a first dimension or a third
dimension without a second dimension.
• The initial values must comply with the tag type and dimensions.
• Whitespace cannot occur within the initial values in L5K format or within
the type/dimension specifier.

TAG
bits : MySint := [0];
dest : INT (RADIX := Decimal) := 0;
overflow OF bits.MyBit0 (RADIX := Binary);
source : REAL (RADIX := Exponential) := 0.0;
timer : TIMER[3] := [[0,0,100],[0,10,100],[0,0,50]];
