List of Control Setup Items
Basic Control Setup Items in Basic Setting Mode
#1 Control action, Input setting
PID number, control period, zone PID, restart mode, restart mode (program) (only on
models with the program control option), initial PID, 6/4 loop select (only on models
with six loops), auto tuning, control mode, method (only during loop control with PV
switching), program control ON/OFF (only on models with the program control
option), PID control mode, burnout, and RJC.
#2 DI/DO/SW registration, AUX (Alarm mode)
Contact input registration, remote setting, alarm mode, SP number selection source,
PV/SP math, CLOG error, and event output setting.
#3 Output processing
Control output, cycle time, and analog-output type
#4 Relay
FAIL ON/OFF, self diagnosis ON/OFF, and relay action/behavior (energize/
deenergize, hold/nonhold)
#5 Tuning setting
Tuning item selection
#6 External loop setting (For details on the settings, see the CX1000/CX2000
Communication Interface User’s Manual (IM 04L31A01-17E) .)
Setup Items in the Control Setting Mode
#1 Control input range
Input type, mode, type, range, span, scale, unit, square root, low-cut, bias, filter, and ratio.
#2 Control alarm
Type, standby, relay output ON/OFF, and alarm value
#3 Operation-related parameters/Zone PID
Suppressing function, ramp-rate-time unit, SP ramp-down-rate/SP ramp-up-rate, tag,
tag comment, reference point (when zone PID is selected), switching hysteresis
(when zone PID is selected), and reference deviation (when zone PID is selected).
#4 PID parameters
SP, PID constant, output limit, shutdown ON/OFF, manual reset, relay hysteresis
(only during ON/OFF control), reverse/direct, and preset output.
#5 Control group setting
Group name, kind (internal loop/external loop/measurement channel), and number.
#6 Ten-segment linearizer I/O
Input type, mode, and biasing or approximation input/output values.
#7 Program control (only when program control is ON)
#1 Program parameter setting
Pattern initial setting, wait action setting, pattern start setting, program pattern
setting, event setting, hysteresis (PV event), and repeat action setting.
#2 Event output setting
#3 AUX (auto message, display position)
#4 AUX (event group)
#8 Detailed setting (When program control is OFF, Detail setting is #7)
#1 Control function
SP tracking, PV tracking, SP limiter, output velocity limiter, and anti-reset windup
auto/manual.
#2 Hysteresis (Alarm)
#3 DIO monitor and operation setting
#4 DI/DO label setting
#9 Control math setting (When program control is OFF, Control math setting is #8)
#1 PV/SP math, Retransmission
#2 Logic math (#1 when both PV/SP computation and analog retransmission are
inactive.)
#3 Constant (#2 when both PV/SP computation and analog retransmission are
inactive.)
