SLC 500 Control System
 |
Bulletin 1747 SLC™ 500 PLC is a chassis-based, modular family of controllers and I/O. With multiple processor choices, numerous power supply options and extensive I/O capacity, the SLC 500 family provides a powerful solution for mid-range stand-alone or distributed industrial control. As one of the first full-featured small controllers on the market, it remains the gold standard in logic controllers more than a decade after its introduction. |
Features
- Up to 64 K words of configurable data and program memory
- Control up to 4096 input and 4096 output signals
- Configure up to three local chassis, with 30 local I/O or communication modules maximum
- Monitor and control remotely located I/O across ControlNet™, DeviceNet™, and Universal Remote I/O links (requires I/O scanner module)
- Built-in ports for EtherNet/IP™, DH+, DH-485, or RS-232 communication
- Available communication modules provide additional communication options
- Specialty modules support simple motion control applications
- Continued support and on-going engineering investment for a large installed base

Chassis
Bulletin 1746 SLC™ 500 Power Supplies provide power to installed controllers or adapters and I/O modules in an SLC chassis. Seven power supplies support a range of AC and DC input voltages.
Communication Interfaces
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.
Controllers
Bulletin 1747 SLC™ 500 controllers provide a range of choices in memory, I/O capacity, instruction set, and communication ports to let you tailor a control system to your exact application requirements. Our controllers have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.
I/O Modules
Bulletin 1746 SLC™ I/O provides a full range of digital, analog, and specialty I/O for a wide variety of applications. You can use the I/O modules in a local I/O chassis of an SLC 500 controller. Or, use an I/O communication adapter module to place I/O in a chassis at a location remote from the controller.
Power Supplies
Bulletin 1746 SLC™ 500 power supplies provide power to installed controllers or adapters and I/O modules in an SLC chassis. Seven power supplies support a range of AC and DC input voltages.
Software
Use RSLogix 500 programming software to program your SLC™ 500 system.
The controller and modules you select, along with your network configuration, determine which additional software packages you need to configure and program your system. Additional required software may include:
