D3 Valve with Gen 2 easy-Drive Actuator
R/W Values
Modbus command value with one implied decimal
place (1000=100.0%). R/W at all times but only used in
R/W 0-1000 Modbus control mode. In on/off mode 0-499 will result
in a move to 0% and 500-1000 will result in a move to
100%.
0=no voltage supplied to terminals,
R/W 0,1 1=voltage supplied to terminals (Only used when
output setup is set for Remote controlled)
Value of 1 will clear faults. Will automatically set back
R/W 0,1
to 0.
Present position of the actuator relative to span with 1
R 0-1000 implied decimal place (1000=100.0%). Valid for all
control modes.
Present position command of the actuator relative to
R 0-1000
span (1000=100.0%). Valid for all control modes.
R 0-65535 Bit flags - see chart
0=no connection between terminals, 1=connection
R 0 - 1
between terminals (Status of digital input or output)
Total number of minutes the actuator has been
R 4294967296
powered on since time has been reset
Total number of minutes the actuator has been at
R 4294967296
100% of travel since time has been reset
Total number of minutes the actuator has been at 0%
R 4294967296
of travel since time has been reset
Total number of close cycles the actuator has
R 4294967296 performed since reset. One open/close cycle counts as
1.
Total number of times the actuator has been powered
R 4294967296
on.
Total number of movements the actuator has
R 4294967296 performed. Move must be at least 5% of rated travel for
cycle to increment.
Value of the analog signal in mA with 2 implied
decimals. In analog control mode, this is the command
value and is subject to the analog settings in registers
R 0-2400
40046 to 40059. Always active but a slower refresh
rate when unit is not in analog control mode.
Diagnostic register - value of incoming voltage with 1
R 0-350
implied decimal.
R 0 - 1 Normally open latch state
