1. Command specific 16 Error Access Restricted Response Codes Command 44 Change Primary Variable Units Code This command is issued to change the units of the Primary Variable which is defined in the DVC2000 as the Analog Input loop current The choices for units are Percent code 57 or Milliamps code 39 This command should be sent prior to a Command 35 which sets the upper and lower Primary Variable range values In addition to changing the units code execution of this command will also change the DVC2000 s Analog Input Upper and Lower Range values to reflect the new units For example When the DVC2000 s Analog Input is configured as 4 20 mA and Command 44 with request Data Byte 57 is executed the DVC2000 s Analog Input units and range values will change to O 100 Likewise When the DVC2000 s Analog Input is configured as O 100 and Command 44 with request Data Byte 39 is executed the DVC2000 s Analog Input units and range values will change to 4 20 mA This command will be accepted when the DVC2000 s Instrument Mode is In Service but will be rejected if Write Protection is in effect Byte Format Description Allowable choices Request R Data Bytes 0 UINT8 Primary Variable Units Code Unit Code 39 mA or 57 Response Data Bytes 0 UINT8 Primary Variable Units Code Unit Code 39 mA or 57 Code Class Description Command 2 Invalid selection Units cod2. Protected prevents configuration and calibration changes to the instrument The default setting is Not Protected Protection is controlled under software control Firmware and Language Pack Upgrade The firmware and language pack of any DVC2000 can be upgraded to the latest version using the Firmware Download tool in ValveLink software The new firmware incorporates all of the new functionality and corrections and improvements made to the technology of the DVC2000 product The firmware download process requires Around 30 minutes to complete e The DVC2000 s instrument mode must be Out of Service e The DVC2000 is powered with 12 mA or greater e That you isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid because the routine will cause the DVC2000 to restart DVC2000 Digital Valve Controller Instruction Manual Supplement August 2014 D103783X012 Dynamic Variables Four Dynamic Variables are implemented Default Meaning Units PV Analog Input mA SV Travel Setpoint TV Pressure PSI BAR KPA FV Travel Device Variables These variables represent measurements taken by the device are read only values and are all in float format These can be read with Commands 33 and 54 Variable ID Meaning Units 0 Analog Input mA 2 Pressure Port A PSI BAR KPA 3 Travel 4 Drive Signal 6
