Type
(1)
Name MB Register Default R/W Values Notes
uint16
Modbus position command
(100=10.0%)
40001 0 R/W 0-1000
Modbus command value with one implied decimal
place (1000=100.0%). R/W at all times but only used in
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%.
uint16 Digital output 40002 0 R/W 0,1
0=no voltage supplied to terminals,
1=voltage supplied to terminals (Only used when
output setup is set for Remote controlled)
uint16 Reset error codes 40003 0 R/W 0,1
Value of 1 will clear faults. Will automatically set back
to 0.

uint16 Actual position (100=10.0%) 40010 0 R 0-1000
Present position of the actuator relative to span with 1
implied decimal place (1000=100.0%). Valid for all
control modes.
uint16
Commanded position
(100=10.0%)
40011 0 R 0-1000
Present position command of the actuator relative to
span (1000=100.0%). Valid for all control modes.
uint16 Diagnostic Flags 40012 0 R 0-65535 Bit flags - see chart
uint16 Digital status 40013 0 R 0 - 1
0=no connection between terminals, 1=connection
between terminals (Status of digital input or output)
uint32 Total Running Time (min) 40014, 40015 0 R 4294967296
Total number of minutes the actuator has been
powered on since time has been reset
uint32 Total Open Time (min) 40016, 40017 0 R 4294967296
Total number of minutes the actuator has been at
100% of travel since time has been reset
uint32 Total Closed Time (min) 40018, 40019 0 R 4294967296
Total number of minutes the actuator has been at 0%
of travel since time has been reset
uint32 Number of Closed (Cycle count) 40020, 40021 0 R 4294967296
Total number of close cycles the actuator has
performed since reset. One open/close cycle counts as
1.
uint32 Number of Power Cycles 40022, 40023 0 R 4294967296
Total number of times the actuator has been powered
on.
uint32 Number of Movements 40024, 40025 0 R 4294967296
Total number of movements the actuator has
performed. Move must be at least 5% of rated travel for
cycle to increment.
uint16 Analog input control value 40026 0 R 0-2400
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
40046 to 40059. Always active but a slower refresh
rate when unit is not in analog control mode.
uint16 Incoming voltage 40027 0 R 0-350
Diagnostic register - value of incoming voltage with 1
implied decimal.
uint16 Latch Open State 40028 0 R 0 - 1 Normally open latch state
