Data Control Instructions
Section 3-18
Bit 00 of C+5 PID forward/reverse
designation
Determines the direction of the
proportional action.
0: Reverse action
1: Forward action
Not allowed
Bits 13 to 14
of C+6
ID starting integral
manipulated vari-
able designation
(unit version 4.0 or
later only)
Determines the initial integral
manipulated variable when PID
control is started (i.e., when the
input turns ON) .
Bit 14 = 0 and bit 13=0:
Start from same integral manipu-
lated value as manipulated vari-
able output designation (Pre-Ver.
4.0 operation).
Bit 14 = 0 or 1 and bit 13 = 1:
Bumpless operation (i.e., start
from an integral manipulated
variable that will not abruptly
change the manipulated vari-
able output and result in a con-
tinuous change).
Bit 14 = 1 and bit 13 = 0:
Start with integral manipulated
variable = 0.
Bit 12 of C+6 Manipulated vari-
able output limit
control
Determines whether or not limit
control will apply to the manipu-
lated variable output.
0: Disabled (no limit control)
1: Enabled (limit control)
Bits 08 to 11
of C+6
Input range
The number of input data bits.
0: 8 bits
5: 13 bits
1: 9 bits
6: 14 bits
2: 10 bits
7: 15 bits
3: 11 bits
8: 16 bits
4: 12 bits
Bits 04 to 07
of C+6
Integral and deriva-
tive unit
Determines the unit for express-
ing the integral and derivative
constants.
1: Sampling period multiple
9: Time (unit: 100 ms)
Bits 00 to 03
of C+6
Output range
The number of output data bits.
(The number of output bits is
automatically the same as the
number of input bits.)
0: 8 bits
5: 13 bits
1: 9 bits
6: 14 bits
2: 10 bits
7: 15 bits
3: 11 bits
8: 16 bits
4: 12 bits
C+7
Manipulated vari-
able output lower
limit
The lower limit for when the
manipulated variable output limit
is enabled.
0000 to FFFF (binary)
(See note 3.)
C+8
Manipulated vari-
able output upper
limit
The upper limit for when the
manipulated variable output limit
is enabled.
0000 to FFFF (binary)
(See note 3.)
Bit 15 of C+9 AT Command Bit
This control bit starts autotuning.
• Set the AT Command Bit to 1
to perform autotuning. (Auto-
tuning can be started while
PIDAT(191) is being exe-
cuted.)
• This bit is turned OFF auto-
matically when autotuning is
completed.
Autotuning will be interrupted if
the AT Command Bit is turned
OFF manually. In this case, the
PID constants will be enabled if
they were already calculated
when autotuning was inter-
rupted.
As a Control Bit:
• 0
→
1:
Executes autotuning.
• 1
→
0:
Interrupts autotuning.
(PID(191) turns the bit OFF
automatically when autotun-
ing is completed.
As a Flag:
0: Autotuning is not being exe-
cuted.
1: Autotuning is being executed.
