was already used for OUT1 or
the PID mode was not used for
OUT1 (in other words PB = 0
and/or TI = 0)
Communication error: wrong
function code
Communication error: register
address out of bounds
Communication error: request
for writing of protected or read-
only data
Communication error: request
to write an out-of-bounds value
in the register
Failure in execution of the
autotune
Impossible to write correctly in
EEPROM
Malfunction of the cold junction
compensation function
Sensor open-circuit or input
current below 1mA if the
controller operates in 4-20mA,
or input voltage below 0.25V if
the controller operates in 1-5V
Malfunction of the A/D
converter or associated
elements
of temperature, the controller
must operate in PID mode (PB
≠ 0, TI ≠ 0) and OUT1 must use
the reverse mode (temperature
rise action). Otherwise, do not
use OUT2 to control a lowering
of temperature.
Correct the communication
software to make it compatible
with the needs of the protocol.
Do not send an out-of-bounds
address to the slave
Do not send protected or read-
only data to the slave.
Do not write out-of-bounds
data in the slave register
The PID values obtained after
the autotune process are out
of bounds. Restart the
autotune.
Do not change the setpoint
value during the autotune
process.
Make the adjustment manually
rather than use the autotune.
Do not set PB to a zero value.
Do not set TI to a zero value.
