Control
56
R/W
Indicates if instrument is in BASIS 1 Protocol mode.
0: Instrument is in BASIS 2 Protocol mode
1: Instrument is in BASIS 1 Protocol mode
Added in V3.0.0.
80
W
Write 0x5214 (21012) to restore factory settings.
512
R/W
The valve control mode, an integer (controllers only):
0: Normal closed loop flow control
Nonzero: Exhaust/Hold for purge mode; drive the valve at the
percentage in register 513.
Added ability to drive at specified percentage in V3.0.0.
513
R/W
The percentage of valve drive to apply in exhaust mode. An
integer where valve drive (%) = value / 100; 0 is fully closed,
10000 is maximum open.
Added in V2.4.0.
514
R/W
Communication watchdog (controllers only), an integer 0–5000.
If zero, the watchdog is disabled. Otherwise, the setpoint is
set to zero if the instrument does not receive a command
addressed to it within every value milliseconds.
The Communication Watchdog is only available when the
setpoint is being set via MODBUS communication and the
Setpoint Source is set to "unsaved digital" (see
). All
other setpoint sources (ASCII, saved digital, analog) are not
impacted by the Communication Watchdog.
Added in V2.4.0.
515
R/W
Autotare enable (controllers only).
0: The instrument never tares automatically.
1: The instrument will tare flow automatically when the setpoint
had been set to 0 for at least two seconds.
Writing any value other than 0 is interpreted as a 1.
Added in V2.4.0.
516
R/W
Setpoint type (controllers only):
0: Analog input.
1: Digital, and the setpoint is saved to flash (not recommended
because the flash burns out easily).
2: Digital, and the setpoint is not saved to flash.
3: No setpoint; the instrument is a meter (the instrument cannot
be set to this value, and this register is read-only when this
value is present).
Added in V2.4.0.
519
R/W
The proportional control gain in the PDF control algorithm
(controllers only). This is an integer from 0–65535. Note that
this register is scaled differently from legacy proportional gain
registers.
Added in V2.4.0.
