PLC-5

Rockwell Automation announces that as of June 2017, the PLC-5 Control System will be discontinued and no longer available for sale. Customers are encouraged to migrate from the PLC-5 Control System to the ControlLogix Control System.

Bulletin 1785 PLC-5® programmable logic controllers (PLCs) offer flexibility in programming, network, and I/O. Designed for larger sequential and regulatory control applications with specialized I/O requirements, PLC-5 control systems bring together existing and new systems through networks such as EtherNet/IP™, ControlNet™, and DeviceNet™. Embedded network ports in PLC-5 controllers enable connectivity to a wide range of devices including MicroLogix™, SLC™ 500, CompactLogix™, and ControlLogix® controllers, letting you expand your control system without additional training investments.

  • Reliability with a Mean Time Between Failure (MTBF) rating that exceeds 400,000 hours
  • 6 K words through 100 K words user memory

Backup options:

  • ControlNet™ Hot Backup module provides control of outputs if the primary controller shuts down
  • PLC-5® Backup Communication module helps increase the fault tolerance of systems controlling I/O on a remote I/O link

I/O support:

  • Monitor and control I/O across ControlNet, DeviceNet™, and Universal Remote I/O links
  • Forcible I/O ranges from 512 through 3072 I/O
  • Maximum remote I/O locations ranges from 5 through 125

Communication ports:

  • On-board ports for DH+, Universal Remote I/O, and RS-232-C/RS-422-A/RS-423-A communication
  • Ethernet or ControlNet dual-media ports included on some controllers
  • Separate modules provide additional communication ports
