Chapter 5 Configure the Configurable Flowmeter Module

5. Choose a 1756-CNB or 1756-CNBR module on the Select Module Type

screen.

6. Configure the remote 1756-CNB or 1756-CNBR module.
7. Add remote flowmeter modules to your configuration through the

remote 1756-CNB or 1756-CNBR module.

8. Configure remote flowmeter modules by using the same procedures

detailed earlier in this chapter to configure local 1756-CFM modules.

IMPORTANT

You must run RSNetWorx™ for ControlNet software for the owner-

controller to establish connections with and send configuration

information to the remote flowmeter module.

1. Select the remote communications module.
2. Click the right mouse button and select New Module.
