Section 3-18
Bit 01 of C+5 PID constant
change enable set-
ting
The timing of enabling changes
made to the proportional band
(P), integral constant (Tik), and
derivative constant (Tdk) for use
in PID calculations. 0: At start of PID instruction exe-
cution
1: At start of PID instruction exe-
cution and each sampling period
Allowed
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.)
