4. the objects supported by the Clinometer The Dual DeviceNet Clinometer is shipped with a MACID set to 63 decimal It is typical for new DeviceNet devices to have a MACID of 63 therefore the MACID should be set to a different network address after the Clinometer is added to a network To avoid conflicting addresses and confusing device identities make sure network address 63 is available before adding the Clinometer to a network When the Clinometer is first added to a network the indicators will show Module solid green indicating that the device is functioning Network blinking green indicating that the device is not connected to any device in the network and IO blinking green indicating that the device has data available but is not being asked to produce data RS Linx will discover the Clinometer and add it to the network as node address 63 DUALINCL The PLC and scanner can request sensor data from the Clinometer using an explicit Get Attribute Single without adding it to the scanner card s scanlist While the Clinometer is processing the explicit message the Network indicator will show solid green but the IO indicator will continue blinking since the device is not being polled If the Clinometer is commissioned and added to the scanner s scanlist all indicators will show solid green indicating that it is working connected to the scanner and being polled Run time data is produced by the Clinometer and is available by execu

6. TI ON The Dual Inclinometer measures inclination in two axis using liquid filled capacitive sensors and outputs the data in response to a poll message from a DeviceNet scanner The nature of the sensors provides a certain vibration dampening effect that is desirable in certain applications The Dual Inclinometer is calibrated to absolute zero level at the factory by establishing an internal offset in software In other words the angle sensors inside the unit are not physically leveled with respect to the enclosure but the unit s software will compensate and give the proper zero degree reading when the unit is level A side effect of this calibration method is that the angular measurement range specification of the sensors will be asymmetrical by their particular amount of offset from zero A similar process can be used after the Dual Inclinometer is mounted to equipment to determine an offset that the equipment logic can use to determine level CONFI GURATI ON The Dual Clinometer is configured via DeviceNet using a configuration device such a handheld Allen Bradley DeviceView or a PC running RS Linx and RS Networx DeviceNet devices use Electronic Data Sheets EDS to provide the information needed to configure the device and setup a scanner and PLC for communication with the device An EDS file for the Clinometer is available on the Matric web site A device profile document is also available which provides additional information on

8. ting a Get Attribute explicit message sequence RS Networx provides a dialog called the Class Instance Editor which can be used to manually execute a Get Attribute request The Clinometer sensor data is the third Attribute 3 in the first Instance 1 of the Assembly Object Class 4 The Clinometer will respond to a Get Single Attribute request by producing two 16 bit values The first word corresponds to the A axis shown on the Clinometer label The second word corresponds to the B axis The most significant bit of the value is a direction bit When the direction bit is set 1 the Clinometer is tilted in the direction as shown on the Clinometer label Data tables and ladder logic can be used to execute the explicit Get Single Attribute request in an operational PLC control system The system integrator will create a data table which holds the explicit request information as shown below An explicit request consists of a Transaction Header followed by Transaction Data In the Transaction Header the COMMAND field is set to 1 to tell the scanner to execute the request the SERVICE field is set to OxOE to request a Get Single Attribute and the SIZE field is 6 to show the number of bytes of transaction data in the request The remaining header field values are chosen by the system integrator In the Transaction Data the first word is the CLASS 4 the second word is the INSTANCE 1 and the last word is the ATTRIBUTE 3 This data is copied by t
