Emerson 400501-08 manual Polled I/O Setup, Example #1 Index SelPredef

Epsilon Ei DeviceNet Drive Reference Manual

5.Install the .eds file in the Master Configuration software (RsNetworx, Wonderware, etc.).

6.Download a configuration for 8 polled input bytes and 8 polled output bytes to be transferred to/from the Ei-DN.

7.Use ladder logic commands to initiate explicit messaging commands over DeviceNet.

Polled I/O Setup

The following examples assume that the user is familiar with and can set up the Ei using the Epsilon Ei Reference Manual (P/N 400507-01). This application example will focus on the DeviceNet setup for the Ei-DN. The setups will demonstrate the Index Sel Predefined, Index Sel User Defined, and Index Type Position Control assembly blocks to transfer DeviceNet bits and initiate indexes.

Example #1: Index Sel(Predef)

This sample procedure for the Index Sel(Predef) assembly block will run preconfigured Index 1 and 2 and Jog while reading back Torque Command and Command Velocity respectively.

1.Start a new Ei-DNconfiguration in PowerTools FM and configure the drive for the particular motor that will be used. (For more information consult the Epsilon Ei Drives Reference Manual (P/N 400507-01).

2.Configure Index 0 as a Incremental Index, Index Count of 1, Distance of 20 revs at a Velocity of 1000 RPM, both Acceleration and Deceleration set to 1000 ms/Krevs/m and a Dwell Time of 0.

3.Enter the DeviceNet setup and set the MacID to 1 and the Baud Rate to 125K. Select the Index Sel (Predef) for both Master Send Assembly Block and Master Receive Assembly Block.
