Series 2000 Communications HandbookDevicenet6.3 THE EDS FILEThe EDS (Electronic Data Sheet) file for the Series 2200e is named 2K2DN.EDS and isavailable from your supplier, or electronically by going to Web site (www.eurotherm.com).The EDS file is designed to automate the DeviceNet network configuration process byprecisely defining vendor-specific and required device parameter information. Following adata sheet metaphor, the EDS file describes a device’s configurable parameters, including itslegal and default values and the public interfaces to those parameters. Software configurationtools utilise the EDS files to configure a DeviceNet network.6.3.1 Polled I/O MessageInput Words Parameter Logical Segment Address1 Measured Value (PV) 20 04 24 01 30 032 Target Setpoint (TS)3 Output Power (OP)4 Summary Output StatusOutput Words Parameter Logical Segment Address1 Setting 20 04 24 01 30 032 AddressTable 6-1: Polled I/O MessagesUsing the Explicit messaging, all controller parameters are accessible using logical segmentaddressing. The Class is always 100 (64 hex), the Instance is always 1 (01hex) and theAttribute values are determined by referencing the parameter tables in the Parameter Mapsection of this addendum. Examples are shown in Table 6-1 for a selection of parameters.Note that the value that changes is the last byte only.Logical segment addresses are encoded to select a particular (Object) Class, Instance, andAttribute ID within an automation device. The Series 2200e supports 8 bit Class and Instanceaddressing. From tables 6-1 and 6-2 in the Logical Segment Address column, the values 20,24, and 30 represent type and format encoding for the Class, Instance, and Attributerespectively. Therefore, from table 6-1, the 04, 01, and 03 define the actual values of theclass, instance, and attribute - respectively - of the Polled I/O message address.Series 2000 Communications Handbook Part No HA026230 Issue 2.0 Feb-00 6-3
