Bulletin 1747 SLC 500 Programmable Logic Controller Communications

SLC 500 Communications

Bulletin 1747 SLC™ 500 Communication Interface Modules let you add another communication port to the SLC 500 controller. This adds network capability beyond the available on-board ports. Some modules provide an interface between a port on the controller and another communication link with a different protocol. Other modules communicate with the SLC processor over the system backplane.

Features

  • DH-485/DF1 communication interface module interfaces the DH-485 port on an SLC™ controller to an RS-232 link
  • ControlNet™ RS-232 communication interface module interfaces the RS-232 port on an SLC controller to a ControlNet link
  • Direct communication module lets the local SLC controller communicate with a supervisory controller across a Universal Remote I/O link
  • Scanner modules communicate with the controller across the backplane and scan I/O across ControlNet, DeviceNet™, or Universal Remote I/O links
  • SLC BASIC modules provide three additional communication ports and run user-written BASIC and C programs
  • SCANport communication module provides a high-speed interface between an SLC controller and up to three SCANport-enabled products
  • RS-232/DF1 port splitter modules let one full-duplex communication port on a controller support simultaneous connection with two external devices
  • Advanced Interface Converter (AIC+) module (1761-NET-AIC) lets you connect two RS-232 devices to a DH-485 network

Applications

The SLC™ 500 family provides cost-effective, reliable control in hundreds of thousands of applications around the world—everything from amusement park rides and micro-breweries to pharmaceutical and food processes. It is well-suited for applications where the size and overhead of a traditional, full-size PLC system is not justified.

SLC 500 controllers are ideal for OEM applications on the following types of machinery:

  • Packaging machinery
  • Conveyors and other material handling machinery
  • Machine tools
  • Textile machinery
  • Food products machinery
  • Pharmaceutical products machinery
