Module Input and Status Data

Scheduled Using RSNetworx for ControlNet.

ControlNet PLC-5 controllers have the ability to perform deterministic transfer of analog module data in the same

ControlNet I/O schedule as discrete I/O. RSNetworx for ControlNet software is used to configure this I/O data

transfer.

A 1771-Generic I/O module Input connection may be used to schedule the Input data from a 1771sc-IFE32 module

to appear in the ControlNet Data Input File of the PLC-5C15 processor.

The configuration data block for the 1771sc-IFE32 must still be sent via CIO instruction. This saves on ControlNet

scheduled bandwidth, allows easy programmatic changes to be made to the module, and, most importantly, prevents

the module from resetting every I/O scan.

1771-Generic module configuration

In RSNetworx for ControlNet versions 2.22 and later, the graphical view of the network allows for a right-click on a

Communications Adapter and the selection of the “Configure Chassis” applet

In the Chassis Configuration applet, the user drags-and-drops the desired modules from an available devices list into

the chassis in the slot locations in which the modules will be installed. In this application, the 1771sc-IFE32 will be

represented by a “1771-Generic” module. This module type will allow us to enter the data lengths required for the

operation of the IFE32 module.

Next, the I/O Connections to the 1771sc-IFE32 must be established. This is done through the Scanlist Configuration

application, which is accessed by right-clicking in the RSNetworx for ControlNet graphical view on a PLC-5C15

controller, and selecting “Scanlist Configuration”.
