2.7 Job list
Function
A job list (loading list) can be created for each workpiece.
This list contains instructions which prepare the following for the
execution of part programs (in several channels if necessary):
• Parallel setup (LOAD/COPY), i.e.:
Main programs and subprograms along with associated data such
as
- Initialization programs (INI)
- R parameters (RPA)
- User data (GUD)
- Work offsets (UFR)
- Tool/magazine data (TOA/TMA)
- Setting data (SEA)
- Protection zones (PRO) and
- Sag/angularity (CEC)
load or copy from the hard disk of the PCU to the main memory of
the NC.
• Preparations for the NC Start (SELECT), i.e.:
Select programs in different channels as well as starting
preparations for execution
• Parallel clearing (reversed LOAD/COPY), i.e.:
Remove/unload main programs, subprograms and associated data
from the NC working memory to the hard disk of the PCU
• Backup (in preparation for the next software version)
Notes
Parallel setup, preparations for NC Start, parallel cleanup and backup
can also be executed from the PLC.
The job list is executed if the workpiece contains a job list of the same
name.
The job list instructions are activated (see diagram) on
1. Parallel setup with "Load" (LOAD/COPY)
1. "Select" (LOAD/COPY/SELECT)
2. "NC Start" (program is executed and SELECT is activated)
3. Parallel clearing with "Unload" (reversed LOAD/COPY)
4. "Backup" (in preparation for the next software version)
