4 System Overview
• multiple controllers joined across networks.
• I/O in multiple platforms that are distributed in many locations and connected
over multiple I/O links.
Choose the processor module with the on-board communication ports you need. You
optionally add modules to provide additional communication ports for the processor. For
I/O in locations remote from the processor, you can choose between a ControlNet,
DeviceNet, or Univeral I/O link. A communication interface module is required in both
the local and remote chassis.
Depending upon the communication ports available on your particular SLC control
system, you can select operator interfaces that are compatible.
Laying Out the System
Lay out the system by determining the amount of I/O necessary, the network
configurations, and the placement of components in each location. Decide at this time
whether each chassis will have its own controller or a networked solution.
SLC 500 processors are available with a large range of memory sizes (1 K…64 K) and can
control up to 4096 input and 4096 output signals. All modular processors except the
SLC 5/01 processor are capable of controlling remotely located I/O. By adding an I/O
scanner module, you can use these processors to control/monitor these remotely located
I/O across ControlNet, DeviceNet, and Universal Remote I/O links.
