B-2
The second word for each loop indicates dynamic-block and auto-tuning
errors for that loop.
Display of integer value in word 4,
7 , 10 , 13 , 16 , 19 , 22, or 25 of the
status block
A nonzero value in
these two digits
indicate an error in the
autotuning process
A nonzero value in
these two digits
indicate an error in the
dynamic block
Example: If a value 6724 is diplayed, the 67 in the upper
pair of digits would indicate an error in autotuning and the 24
in the leastsignificant pair of digits would indicate an error in
the dynamic block
If This Word of
Status Block:
Contains This
Value:
The Error is:
4 (loop 1)
7(loop2)
xx00 No error detected in dynamic block.
7 (loop 2)

A word in the dynamic block has an outofrange value
or incompatible bit selection. Locate the specific word
by the value in the 2 leastsignificant decimal digits of
the status word. (value = word)
•Example: If the value in word 13 is xx17, word 17
(loop4 manual output value) of the dynamic block
has an outofrange value,
00xx No error in autotuning the loop.
65xx Autotuning terminated because of thermal runaway.
66xx Autotuning terminated because the change in PV
(since initial PV temperature) has exceeded 200

.
67xx
Autotuning terminated because PV is within 50

of
setpoint.
