CHAPTER 3

HOST COMMUNICATIONS

COMMS PROTOCOL OPTIONS

GEM This configuration implements the SMEMA standard for communications for

Surface Mount Equipment. GEM (Generic Equipment Model) is a standard

sub-set of the SECSII protocol. GEM is specifically designed for implementing

equipment automation in a production environment.

In this configuration, a host computer running GEM compatible software talks to

the machine via a Network cable.

If the Host is a PC, DEK’s Off-line editor software can be used to modify

product files. The Event Log can be read by a text editor. The flexibility of the

GEM interface allows data collection to be customized to meet the users

requirements.

Net_Files This configuration allows users to redirect files away from the machines local

hard drive to a remote directory on a file server. The machine is configured to

access a ‘product’ directory for a product file and a ‘data’ directory for output

data files.

At the machine when a product file is loaded it is read from the ‘product’

directory on the network file server. When it is saved it is saved to the ‘product’

directory on the file server. Files cannot be read from the printer or sent to the

printer across the network.

Once the files are present on the server, they can be accessed from a networked

PC without interfering with the machine.

At a networked PC, DEK’s Off-line Editor software can be used to modify

product files. QC-Calc software can be used to access SPC data in the

‘READINGS.DEK’ file. The Event Log can be read with a text editor.
