Control bits Notes
C_DOPARAM Change function of DO1 (see figure below)
The value from byte 0 is adopted as the new function of DO1.
C_INTTIME Change integration time (see figure below)
The value from bytes 0 and 1 is adopted as the new integration time for the next measurement.
CTRL_DO1 Enable DO1
You use this bit to enable the DO1 output.
CTRL_DO2 Enable DO2
You use this bit to enable the DO2 output.
EXTF_ACK Error acknowledgment
The error bits must be acknowledged with the EXTF_ACK control bit after the cause is removed. (see
figure below)
LOAD_PREPARE Load high limit (see figure below)
The value from bytes 0 to 3 is adopted as the new high limit.
LOAD_VAL Load low limit (see figure below)
The value from bytes 0 to 3 is adopted as the new low limit.
RES_STS Start resetting of status bit
The status bits are reset by means of the acknowledgment process between the RES_STS bit and
the RES_STS_A bit. (see figure below)
SET_DO1 Control bit DO1
Switches the DO1 digital output on and off when CTRL_DO1 is set.
SET_DO2 Control bit DO2
Switches the DO2 digital output on and off when CTRL_DO2 is set.
SW_GATE SW gate control bit
The SW gate is opened/closed via the control interface with the SW_GATE bit.
