7.3 Error detection and diagnostics
Feedback interface ERR bits
Your program can access power supply error and output load status directly, through a
channel's feedback interface.

Byte 0: Bit 0 Byte 8: Bit 0
Byte 0: Bit 1 Byte 8: Bit 1
Byte 0: Bit 2 Byte 8: Bit 2

Note
If an output short-circuit occurs, the digital output is able to briefly supply a current
substantially higher than the rated value.

Feedback bit Meaning
ERR_PWR Indicates under voltage on the power
supply. Note that the bit is not set, if the
voltage is not present.
ERR_24V Indicates a short-circuit or under voltage
condition on the 24V sensor power sup-
ply.
ERR_LD Indicates an error occurred when loading
a parameter value through the SLOT field
using the single-update method.
ERR_PULSE Indicates a pulse output error in the Pulse
output, On/Off-delay, and Pulse train
modes
ERR_DQA Indicates a short-circuit or overload of
DQn.A digital output.
ERR_DQB Indicates a short-circuit, overload of
DQn.B digital output. Also, indicates an
attempt to set one channel's DQn.A and
DQn.B to the high state (using SET_DQA,
SET_DQB, and TM_CTRL_DQ).
ERR_OUT_VAL Indicates the value in OUTPUT_VALUE is
not valid
ERR_SLOT_VA The value in SLOT is not valid (when
L MODE_SLOT = permanent update)
Value range
0 = PWR is not in under voltage
1 = PWR is detected but in under
voltage
0 = 24 V DC sensor supply work-
ing normally
1 = 24 V DC sensor supply short-
circuit or under voltage
0 = No SLOT single-update error
1 = SLOT single-update error
0 = No pulse output error
1 = Pulse output error
0 = No DQn.A digital output short-
circuit or overload
1 = DQn.A digital output short-
circuit or overload
0 = No DQn.B digital output short-
circuit or overload
1 = DQn.B digital output short-
circuit, overload, or attempt to set
DQn.A and DQn.B high.
0 = No OUTPUT_VALUE error
1 = Error in OUTPUT_VALUE
0 = No SLOT value error
1 = SLOT value error
