Configuring the DeviceNet Network

Connection Types

The Epsilon Ei-DN DeviceNet interface was designed to communicate with a DeviceNet network in two ways. Polled I/O connections and Explicit Messaging connections can be used to access all read or read/write data from the Epsilon Ei-DN.

Polled I/O Connections (Implicit Messaging)

The Poll Command is an I/O Message that is transmitted by the Master. A Poll Command is directed towards a single, specific Slave (point-to-point). A Master must transmit a separate Poll Command Message for each one of its Slaves that is to be polled. The Poll Response is an I/O Message that a Slave transmits back to the Master.

A Polled Message contains I/O data that can be read by the PLC on every scan. Polled messages are used for high priority data and are typically used to transmit parameters, such as index initiates or position feedback.

Explicit Messaging

Explicit Messages are initiated from a user-created program inside a PLC or PC-based software program. In a PLC, these messages are sent and received using the PLC-specific explicit message setup. Using Explicit Messaging, all user parameters can be accessed in the Ei-DN drive. These messages allow parameters to be sent in messages that may take multiple scans of the PLC. Explicit Messages are lower priority than Polled I/O messaging connections and work well for transferring recipes or any 32 bit parameters to the drive.

Software Interface

This section discusses how to configure a DeviceNet Network with PowerTools FM software and discusses the parameters that appear on the tabs related to DeviceNet configuration. Other tabs are described in the Epsilon Ei Indexing Drive and FM-2 Indexing Module Reference Manual (P/N 400507-01).

DeviceNet Tab

The DeviceNet tab allows the user to configure DeviceNet parameters and watch the DeviceNet Parameters while online with the drive through PowerTools FM. The DeviceNet tab has two sub-tabs: DN Setup and Online.

The DN Setup tab allows the user to set up MacID, Baud Rate, choice of predefined assembly blocks, and host-mode enable as well as display the fixed assembly block word mapping.
