The Intermediate I course explored the Compare, Compute, Data Conversion,
File Manipulation, and Message instructions. The Intermediate II course
continues the investigation of the File Manipulation and introduces the
Bit manipulation instructions. Programs using these instructions include
data gathering, calculations, date and time stamping, shift reports, data
concentration, totalizing, averaging, etc.
The Intermediate II course further develops the skills necessary to trace
the flow of word information into, through, and out of logic programs
using the word and file manipulation instructions. This additional programming
knowledge provides the ability to comprehend and troubleshoot detailed
control circuits. In addition, the system status and diagnostic data access
instructions (SSV, GSV) are further explored and used to help diagnose
and solve in-plant control problems more quickly.
Refresh knowledge of the major functional components of the Allen-Bradley
ControlLogix programmable control system as it relates to your facilitys
Discuss design considerations for system architecture and communication
Refresh knowledge of the memory layout and configuration of the Logix
(ControlLogix) processor, including tags, data types, tasks, programs, and
Develop a thorough understanding of the uses of and applications for User
Defined Data Types.
Re-examine differences and capabilities of Local, Universal Remote, DeviceNet,
ControlNet, and Ethernet I/O systems.
Refresh knowledge of the Contact, Coil, Timer, Counter, Comparison, Math,
and Data Conversion instructions.
Further explore and test the functionality of the File Manipulation and
Introduce the Bit Manipulation instructions.
Read and write information on a communication network using the Message
instruction and Produced/Consumed tags.
Access and manipulate processor status and configuration information with
the Get System Value (GSV) and the Set System Value (SSV) instructions.
Create methods to test programs, develop traps, and follow the flow of
information through a series of instructions.
Develop advanced troubleshooting skills, learn to gather clues to help
eliminate non-problem spots, and draw attention to possible problem areas.
Use the programming software as a diagnostic and troubleshooting tool.
Develop a thorough understanding of, and the safety issues related to,
Forcing in the Logix (ControlLogix) PLCs.
Discuss appropriate safety issues. (Is the circuit really off??)
