Chapter 1 Introduction
1-4
(11) Built-in PID (“S(U)” type main unit)
(a) Supporting max. 16 loops.
(b) Setting parameters by using XG5000 and supporting loop status monitoring conveniently with trend
monitor.
(c) Control constant setting through the improved Auto-tuning function.
(d) With many other additional functions including PWM output, ∆MV, ∆PV and SV Ramp, improving the
control preciseness.
(e) Supporting types of control modes such as forward/backward mixed operation, 2-stage SV PID control,
cascade control and etc.
(f) A variety of warning functions such as PV MAX and PV variation warning securing the safety.
The following table gives definition of terms used in this manual.
A standard element that has a specified function which configures
the system. Devices such as I/O board, which inserted onto the
mother board.
Example)
Expansion module,
Special module,
Communication
module
A single module or group of modules that perform an
independent operation as a part of PLC systems.
Example)
Main unit,
Expansion unit
A system which consists of the PLC and peripheral devices.
A user program can control the system.
A program and debugging tool for the MASTER-K series.
It executes program creation, edit, compile and debugging.
(PADT: Programming Added Debugging Tool)
Software to execute description, edition of basic parameter, high
speed link, P2P parameter, and function of communication
diagnosis
Internal memory area of the CPU module which used to hold I/O
status.
Abbreviation of „Real Time Clock‟. It is used to call general IC that
contains clock function.
Supervisors the pre-set execution times of programs and warns if
a program is not competed within the pre-set time.
