Description

The function of the Semiconductor

Equipment Communication Stan-

dard (SECS) II is the uniform defini-

tion of communication interfaces

to the production equipment ob-

tained from different manufactur-

ers. It has been further developed

into GEM Standard (General

Equipment Model) which is also

suitable for SMT production facili-

ties. To this end, an external user-

specific production computer

(host) is connected via LAN to a

GEM computer integrated into the

machine control. The interface is

used by host systems created by

the user or by application software

from a third-party manufacturer.

The SECS II / GEM communication

protocol supports central control,

process control and their data

management of entire production

lines at the line computer. It is

possible through Statistical Proc-

ess Control (SPC), for example, to

effect preventive maintenance

which eliminates or greatly re-

duces non-productive time.

The product Remote Support en-

ables online access to the line

computer, station computer and

machine controller of SIPLACE

placement systems from the sup-

port centers in Munich, Norcross

and Singapore. The SIPLACE ex-

perts in the pertinent support cen-

ter can employ remote data and

the program files of the individual

SIPLACE lines in Production to an-

swer all questions about the

placement systems, immediately

and online.

Remote Support is offered on the

basis of communication via ISDN

(Integrated Services Digital Net-

work). Due to its high data trans-

mission speed (64,000 or 128,000

bits/s) ISDN is an ideal medium for

high-speed transfer of large quanti-

ties of data, the SIPLACE expert at

a “Remote Support Position”,

which consists of one line com-

puter, one station computer and a

communications router, can log

himself or herself into the corre-

sponding computers of the

SIPLACE line in the customer's

plant. Remote Support positions

are available in Munich, Norcross

and Singapore. An ISDN router is

also installed at the SIPLACE or

site LAN of the customer. There

need be only one such router per

production facility, however, if the

lines at the customer's site are in-

terconnected via a site LAN.

Basically, the same functionality is

available via Remote Support as is

possible at the local computers

(line computer, station computer

and machine controller).

To comply with the customer's

need for security where sensitive

production data are involved, many

mechanisms (automatic callback,

password protection, switch-off

mode, etc.) are integrated into the

system and can be applied specifi-

cally.
