Structured Text for Studio 5000: A Practical Guide to Programming Allen-Bradley ControlLogix and CompactLogix PLCs in ST

By Grant R. Whitfield

Ladder is the Rockwell default - but recipes, scaling, totalization, and
real sequences are exactly where it gets painful. That is where Structured
Text pulls ahead, and this is the practical book on ST in Studio 5000 Logix
Designer the ControlLogix world has been missing: current, honest, and built
around a machine you actually program, not disconnected snippets.

Structured Text for Studio 5000 takes you from your first ST routine to a
complete, running wet-well lift station - lead/lag/standby pumps, level
control, flow totalization, runtime balancing, and a full alarm and interlock
layer - assembled the way a working controls engineer builds it. Along the
way you learn the language properly: tags and scope, data types and UDTs,
IF/CASE and loops, arrays, timers and counters, Add-On Instructions, state
machines, analog scaling, and fault handling. Every line of ST is explained
line by line - never shown and left for you to guess.

Written for the ladder programmer moving to ST, the automation student, and
the working engineer who wants clean, modern Structured Text on Logix.

You'll be able to:
- Read and write Logix ST fluently - scope, data types, expressions, control flow
- Model machines and recipes with UDTs and arrays
- Build reusable Add-On Instructions (AOIs) in ST
- Write CASE state machines for real sequences
- Scale analog, totalize flow, and balance pump runtime
- Assemble a complete, alarmed, interlocked ControlLogix program end to end
