Chapter 2

Planning to Use Your ControlNet PLC-5

Processor

Using This Chapter

To distinguish phase 1.5 ControlNet processors from earlier phase

processors, new catalog numbers were created for each of the phase

1.5 ControlNet processors: 1785-L20C15, 1785-L40C15, L46C15,

and 1785-L80C15.

Understanding

ControlNet I/O

The ControlNet system is designed to:

• provide high-speed, repeatable, deterministic I/O transmission

• allow control and message information to co-exist on the same

physical media

• make sure that I/O data transfers are not affected by

- programming-terminal message activity

- inter-PLC processor message activity on the network

You cannot mix phase 1.5 and earlier phase (such as

1.0 and 1.25) products on the same ControlNet

network.
