Week 8
Reading Assignment:
Chapter 6, PLC Programming,
- Creating and Printing PLC Program Reports, Text page 128, Lab Manual page 39.1
- LAB NOTEBOOK Pages 39_45
- Internal Coils. Addressing and implementations.
- Example usage page 37 in the loose leaf lab notebook (llln).
- Implementation on page 39, Excersise Two, Start/Stop control, in the loose leaf lab notebook (llln).
- Use of Internal Coils to Minimize the use of input and output addresses in PLC programs, pages 52, 53, 54, in the loose leaf lab notebook (llln).
- Sample RSLogix implementation file, INTERNALCOILS.pdf
- Review the exercises pages 39 – 46 in the loose leaf lab notebook.
- Review the three phase motor starter connection diagrams on pages 41 and 42.
- Review Latch/Unlatch coils and implementations.
- DOCUMENTATION, labeling rungs and instructions.
Laboratory objectives:
- Complete the exercises pages 39 – 46 in the loose leaf lab notebook and save the files to a folder. Start building a “PLC ladder logic file portfolio”. Programs must be complete with Name, Date, file title, and PLC element and rung labels.
- Homework and Laboratory Assignments: Preparation for lab practical #2, __________ (date as assigned).
- AB RSLogix 500 programs for the following ladder logic programs:
- Forward, Reverse, Jog Forward, Jog Reverse, and Stop inputs with coil interlock design and seal-in coils.
- Forward, Reverse, Jog Forward, Jog Reverse, and Stop inputs with pushbutton interlock design and seal-in coils.
- Forward, Reverse, Jog Forward, Jog Reverse, and Stop inputs with coil interlock design and latch/unlatch coils.
- Forward, Reverse, Jog Forward, Jog Reverse, and Stop inputs with pushbutton interlock design and latch/unlatch coils.
- Each program should be implemented using internal coils to minimize the use of input and output addresses. This will allow easy program modifications. All elements should have a descriptive label and each rung an appropriate comment.
- You will be required to make the necessary connections between the Micrologix 1000 PLC, push buttons, solid state relays, a three phase motor starter, and a three phase motor to demonstrate the operation of the program assigned. A connection diagram will also be required.
