9. Communication functions

(1) Communication items

Supervisory items:

From CC-S to host

Process variable, set point, manipulated

out-put, deviation, operation mode, alarm

in-formation, fault information, PID para-

meters, various limiter values, constants,

segmented line, analog input/output,

digital input/output, configuration program

(Wafer connection) etc.

Setting items: From host to CC-S

Set point, manipulated output, operation

mode, PID parameters, various limiter

values, constants, segmented line, con-

figuration program (Wafer connection)

etc.

(2) Communication enable/inhibit:

Data setting from the host can be enabled/inhibited by

F/S ,

,

,

, ST keys on the front panel.

(3) Communication interface

RS-422:

Universal interface

Transmission speed:

2400, 4800, 9600 or 19200 BPS selectable

No. of units connectable:

31 max.

Code format: One or two stop bits, parity EVEN/ODD/

NONE selectable.

Transmission distance:

1 km max.

10. Personal computer software packages

Two software packages, running on IBM PC-AT, are

provided for CC-S supervision, operation, maintenance

and configuration.

They are Fix software packages and CC-S configurator.

Fix is a user-configurable, menu-driven software packages

for CC-S supervision, operation and maintenance, while

CC-S configurator is another package to configure CC-S

control system.

E.g. Real time process display

Process Alarming

Trending

Control Strategy Configuration

Fix is a trade mark of Intellution Inc./U.S.A. Standard software

packages for plant supervision, operation and maintenance are

available under Fix:

11. Security functions

Data security function by means of pass code.

12. Operating conditions

Supply voltage: 24V DC (20 to 30V DC), 110V AC (85 to

132V AC), 220V AC (187 to 264V AC)

Power consumption:

Approx. 13W (DC), 20VA (AC)

Power factor: approx. 0.6

Dielectric strength:

Balanceless bumpless

Balance bumpless

7. Power failure and restart function

Power failure detection:

Control function interrupted at power

failure detection.

During power failure:

Operating parameters backed up by ca-

pacitor when power failure within 5

minutes.

Initial set point and control output values,

PID parameters etc. are stored in non-

volatile memory (lasts for 10 years or

longer at ambient temperature of 50

°C or

less)

Restart from power failure:

Initial or continuous start is selectable for

power failure within 5 minutes.

Restart from power failure lasting longer

than 5 minutes is made by initial auto-

matically.

Control mode at initial start is selectable from.

R:

Remote mode

M:

Manual mode

A:

Automatic mode

SCC: SCC mode

8. Self-diagnosis functions

Computation/control function failure:

FLT indicator lights up, FLT contact output

closes, and computation and control func-

tion interrupted.

Manipulated output can be controlled

manually at FLT (Soft manual).

Input signal and control output failure:

FLT indicator lights up, FLT contact output

closes, control stops, and manipulated

output is held, while other computation

and control functions continue to be pro-

cessed.

Fault indication: Cause of fault is indicated numerically on
