5.6 Process Program Management
This capability provides the host with the ability to control process program (product)
distribution between DEK printers. This is achieved using the following functionality.
Each printer has a process program create / edit capability. When the operator creates a new
process program or modifies an existing one, a collection event report is generated (if enabled
by host). The host uses the event reports (3.2.1) to set up the techniques to link the machine
variables, pp_old_file_name and pp_change_status to the process program change event.
The host can upload and download, new / changed programs from and to printers. The host can
also delete and rename programs resident on a printer. It can also request a directory of
programs resident on a printer. Finally, the Equipment can upload and download new / changed
programs from and to the Host. See Appendix B for Operator procedures.
Using these functions, the host can maintain a master program library and force consistency
across multiple printers.
The DEK printer supports only unformatted process programs. Modification of the process
program is not permitted while the machine is running.
Start Modification >>>
The printer stores a single process program in a number of separate data files (e.g. pr1, isd,
pxf). When the printer transfers a process program to the host, the individual files are
combined into a single block of data. When the host transfers a process program back to the
printer, the printer splits the data back into the individual files. The internal contents of the
process program data and the combining/splitting of the files is transparent to the host. This
data can be saved to persistent storage on the host, however this data should never be manually
copied (e.g. via a network or memory stick) to the printer. DEK recommends that any product
data stored on the host should be written to a file with a .PRC extension (C = compound) to
mark it as different from the individual product files. The details of the individual files are
beyond the scope of this document.
For backward compatibility, product files already held on the host can still be received and
understood by the printer. If there is a requirement to only transfer the individual PR1 file and
not the other supporting files, then equipment constant CompoundProductFiles (ECID 46) will
allow this feature to be overridden.
<<< End Modification
Note: Full process program management is only permitted when the machine is in the READY
machine state and in the ON-LINE:REMOTE control state. In the READY machine state and
ON-LINE:LOCAL control state, Host initiated process program management is limited to
Directory Request only.
Note: The printer normally allows limited adjustment of the process parameters, locally by the
operator or via the remote command “ADJUST_PARAMETER”. This can be altered by setting
the Equipment Constant “process_adjustments” to disable operator, remote or both.
