Epsilon Ei DeviceNet Drive Reference Manual
The Epsilon Ei-DN configuration is easily set within PowerTools FM software. In PowerTools FM software, the user has the option to select between 8 predefined assembly blocks to be transferred using polled data (8 bytes input, 8 bytes output polled data length per drive). The Ei-DN additionally allows the master to set up an explicit messaging connection to access all user accessible parameters within the Epsilon drive through PLC logic.
The Epsilon Ei-DN drive has passed internal tests for conformance as a group 2 DeviceNet slave.
DeviceNet Overview
DeviceNet is a low-level network that provides connections between simple industrial devices (sensors, actuators) and higher level devices (industrial PLC’s). DeviceNet standards and specifications are managed by the Open DeviceNet Vendors Assoc. (ODVA) which is an independent supplier organization that manages the DeviceNet specification and supports the worldwide growth of DeviceNet and Ethernet IP.
DeviceNet Communications Link
DeviceNet has two primary purposes:
1.Transport of control-oriented information associated with low-level devices.
2.Transport of other information that is indirectly related to the system being controlled, such as configuration parameters.
The list below presents a summary of the Physical/Media specific characteristics of DeviceNet:
1.Trunk-line/drop-line configuration (See Figure 2, “Master/Slave Relationship” on page 4.)
2.Support for up to 64 nodes
3.Node removal without severing the network
4.Simultaneous support for both network-powered (sensors) and self-powered (actuators) devices
5.Use of sealed or open-style connectors
6.Protection from wiring errors
7.Selectable data rates of 125k baud, 250k baud, and 500k baud
8.High current capability (up to 16 amps per supply)
