Before You Begin

The ControlNet network is a high-speed link that lets PLC processors and I/O devices (e.g., I/O racks, variable speed drives, Man-Machine

Interface (MMI), and other automation devices) exchange data. The

ControlNet PLC-5 processors have one logical ControlNet port consisting of two BNC connectors and one network access port; these processors let you connect to the ControlNet network.

If you need more information, see the ControlNet PLC-5

Programmable Controllers User Manual, publication number

1785-UM022 (see page P-1 for information about how to obtain a copy of this manual).

ATTENTION:

Make sure you understand the anti-static environment.

The processor is shipped in a static-shielded container to guard against electrostatic damage. Electrostatic discharge can damage integrated circuits or semiconductors in the processor module if you touch backplane connector pins. It can also damage the module when you set configuration plugs or switches inside the module. Avoid electrostatic damage by observing the following precautions.

• Remain in contact with an approved ground point while handling the module (by wearing a properly grounded wrist strap).

• Do not touch the backplane connector or connector pins.

• When not in use, keep the module in its static-shielded container.

Use the following software packages to montior ControlNet configuration and status information.

Use: To:

RSNetWorx for ControlNet

RSLogix5 define ControlNet network parameters, such as:

• network update time

• media redundancy

• physical media configuration

• maximum scheduled nodes

• maximum unscheduled nodes

• monitor I/O map entry status

• monitor ControlNet diagnostic file

1

• enter user program files

• create/delete/monitor data table files

• enter module configuration

• enter channel 0, 1A, 1B, and, 3 configuration

• administer passwords and privileges

RSLinx to provide the ControlNet network interfaces to:

• poll the network for active devices

• monitor station diagnostics
