Rockwell Automation 1772-LV,D17726.6.1 A and I MNL MINI-PLC-2/15 PROCESSO - Manual (Page 5)

Introduction
Chapter 1
1Ć2
The Processor stores all I/O device status data in a central read/write memory.
This allows the latest status data to be accessible during the scanning of the user
program. PC programming instructions allow the Processor to perform:
Timing/Counting operations
Arithmetic (+, -, x, :) operations
Data transfers and comparisons
Program
Jumps/subroutines
Word/File transfers
Sequencer operations
Block transfer operations
Data highway communication
The Mini-PLC-2/15 Programmable Controller uses readily understandable
symbols in a ladder diagram format. The ladder diagram program is manually
entered into memory using an Industrial Terminal. An Industrial terminal is
also used to edit the program and monitor the status of the user’s I/O devices as
well as interface the Mini-PLC-2/15 Processor with a peripheral device.
Peripheral devices including keyboards/printers, the Digital Cassette Recorder
(Cat. No. 1770-SA) and the Data Cartridge Recorder (Cat. No. 1770-SB) allow
a variety of additional capabilities:
loading/storing/verifying the program using magnetic tape
generating a hard-copy printout of the ladder diagram program or total
memory
generating various types of reports in a user-programmed format
Indicators on the various Controller components are used to show I/O device,
Processor, and power supply status. These indicators help to diagnose a fault
situation quickly when troubleshooting the PC system.
Read this manual carefully before assembling or installing any component. It is
strongly recommended that the hardware and installation personnel work
closely with the Mini-PLC-2/15 programmer at start-up.
Certain aspects of the programmable controller may be new to many
individuals. For this reason, Publication SG1-1.1, “Application Considerations
for Solid State Controls” should be read, as it provides general background
information on solid state controls.
WARNING: To avoid personal injury and equipment damage,
completely read and thoroughly understand the contents of this
Manual before attempting to assemble and install the Mini-PLC-2/15
Controller and/or any of its components.
