Allen-Bradley Programmable Controllers | PLC-5 System

The PLC-5® processor module in a 1771 platform provides a proven approach for industrial control. PLC-5 processors are high-speed, single-slot processors used for control and information processing. They are designed for larger sequential and regulatory control applications with specialized I/O requirements and/or the need to coordinate with other processors and devices.

PLC-5 processors are available in a range of I/O capacity and memory size, and can be connected in a variety of networks for distributed processing and distributed I/O. The 1771 I/O products offer a full range of digital and analog I/O (including intelligent I/O) in a rugged modular assembly.

PLC-5 System Benefits

  • Modularity — Modular I/O and communication interfaces provide a configurable and expandable system. A system should be configured for the required number of I/O and the communication networks. Later, when system expansion is necessary, I/O or communication interfaces can be added.
  • Speed — Fast delivery of messages between networks, between links within networks, and between modules across the backplane.
  • Toughness — Industrially-hardened hardware platform is designed to withstand the vibrations, thermal extremes, and electrical noise associated with harsh industrial environments.
  • Broad I/O options — A large selection of 1771 I/O modules available for use in the local I/O chassis, and an even larger selection of I/O available at locations remote from the processor, can be connected across ControlNet™, DeviceNet™, and Remote I/O links.

Allen-Bradley PLC-5 System Overview

PLC-5 processors are available in a range of forcible I/O (512 maximum through 3072 maximum) and maximum user memory (6K through 100K words). All are capable of controlling remotely located I/O. The maximum number of I/O locations remote from the processor ranges from 5 through 125. The processor can monitor/control these I/O across ControlNet, DeviceNet, and Remote I/O links.

The 1771 platform provides a rack-based modular assembly. The PLC-5 processors are single-slot modules that are placed into the left-most slot of a 1771 I/O chassis. For 1771 I/O in a location remote from the processor, the I/O adapter is a single-slot module that is placed into the left-most slot of a 1771 I/O chassis. Some 1771 I/O chassis are built for back-panel mounting and some are built for rack mounting. The 1771 I/O chassis is available in sizes of 1, 2, 4, 8, 12, or 16 I/O module slots. The 1771 I/O modules are available in densities of a maximum of 32 I/O per module. Mechanical keying of each I/O module to its backplane connector guards against inadvertently replacing a module with another module of a different type. Because external connections are terminated at a wiring arm that unplugs from the module, there is no need to disconnect wiring to replace an I/O module.

Power supply modules are available for installation in I/O module slots. Also stand-alone power supplies are available and can be mounted separately or directly on the left end of the 1771 I/O chassis.

Allen-Bradley PLC-5 Processors Overview

The PLC-5® processors are single-slot modules that are placed into the left-most slot of a 1771 I/O chassis. They are available in a range of I/O, memory, and communication capability.PLC-5 Processors

PLC-5 processors have ports configurable for either a Data Highway Plus messaging communication link or a Universal Remote I/O link. As a Universal Remote I/O port, it can be configured as either an I/O scanner port or an I/O adapter port. As an I/O scanner port, it monitors and controls the I/O on the link by communicating with the I/O adapters for those I/O. As an adapter port, it communicates only with the I/O scanner port on the link, passing a maximum of one I/O rack of input and output data between the two to provide distributed processing.

All PLC-5 processors have Data Highway Plus and RS-232-C/422-A/423-A communication ports. In addition to these ports, each Ethernet PLC-5 processor has an Ethernet communication port, and each ControlNet PLC-5 processor has a ControlNet communication port.

Although each Ethernet PLC-5 processor has on-board Ethernet ports; additional Ethernet ports can be added to any PLC-5 processor system with a 1785-ENET Ethernet Interface Module. PLC-5 processors do not have an on-board DeviceNet port. A DeviceNet port can be added to the system with a 1771-SDN scanner module.

  • Multiple main control programs for segregation of control tasks
  • Processor input interrupts and global status flags
  • Programmable fault response for reacting to a fault before the system goes down
  • Timed interrupt routine for examining specific information at specific time intervals
  • Protected memory selectable by word on selected processors
  • 512 through 3072 maximum forcible I/O in any mix
  • Up to 50,176 maximum non-forcible I/O
  • Processor-resident local I/O (1771 I/O modules)
  • Extended-local I/O on selected processors (1771 I/O modules)
  • Universal Remote I/O (1746, 1771, and 1794 I/O modules and 1791 I/O blocks)
  • DeviceNet I/O (1794 I/O modules, 1792D I/O blocks)
  • ControlNet I/O on selected processors (1771, 1734, 1794, 1797 I/O modules)
  • Universal Remote I/O ports can be configured as either an I/O scanner port or an I/O adapter port
