4.5 Equipment Constants

This capability enables the host to read and set the value of the equipment constants defined in

chapter 7. For this purpose, the following functionality is provided.

Host can send a list of equipment constant identities ECID's and values ECV's.

Host can request current ECV's.

Host can request a list of EC names.

Scenarios:

Host sends equipment constants:

Comments Host Equipment Comments

List of constants and values S2F15 -->

<-- S2F16 Acknowledge

Host equipment constant request:

Comments Host Equipment Comments

Request constants S2F13 -->

<-- S2F14 List of ECID's and ECV's

Host equipment constant namelist request:

Comments Host Equipment Comments

Request constant namelist S2F29 -->

<-- S2F30 EC Name list

Operator changes equipment constant:

Comments Host Equipment Comments

<-- S6F11 Equipment sends EC change event

Host Acknowledges change S6F12 -->

4.6 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.

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.

Scenarios:

Operator creates / changes equipment process program:

PPCHANGENAME / PPCHANGESTATUS are

updated.
