1772-LN3 Allen Bradley AB Mini PLC / Programmable Controller - No Key
Allen Bradley Mini Processor / Programmable Controller, Part No. 1772-LN3 - No Key
The Bulletin 1772 Mini-PLC-2 Programmable Controller is a rugged, solid state programmable controller that consists of the MiniPLC-2 Processor (Cat. No. 1772-LN1, -LN2 or -LN3) and the 1771 1/0 Family of racks and modules. With a user-written program and appropriate 1/0 modules, the Mini-PLC-2 Controller can be used to control many types of industrial applications such as:
• Process control
• Material handling
• Palletizing
• Measurement and gaging
• Pollution control and monitoring
The Mini-PLC-2 Processor has a Read/Write CMOS memory that stores User Program instructions, numeric values and 1/0 device status. The User Program is a set of instructions in a particular order that describes the operations to be performed and the operating conditions. It is entered into memory, instruction by instruction, in a ladder diagram format display from the keyboard of the Industrial Terminal (Cat. No. 1770-T1, -T2 or -T3). Some ladder diagram symbols closely resemble the relay symbols used in hardwired relay control systems.
During program operation, the Mini-PLC-2 Processor continuously monitors the status of input devices and, based on User Program instructions, either energizes or de-energizes output devices. Because the memory is programmable, the User Program can be readily changed if required by the application.
In addition to ON/OFF control, the Mini-PLC-2 Controller can perform additional functions such as:
• Timing/Counting operations
• Arithmetic (+, -) operations
• Arithmetic (x, +) operations (1772-LN3 Processor)
• Data comparisons
• Block Transfer (1772-LN3 Processor Module)
• 1/0 Forcing
• Data Highway and RS-232-C interfacing
When the Industrial Terminal (Cat. No. 1770-T1, -T2 or -T3) and the Mini-PLC-2 Programmable Controller are used together or with additional peripheral devices, application data can be recorded or displayed using a variety of peripheral functions:
• Report generation
• Contact histogram (the ON/OFF history of a bit in memory)
• Recording/loading/verifying the User Pro- gram using magnetic tape
• Hard-copy printout of the User Program or the complete memory
