2. Application systems
This section describes the configuration of application system and their related setting with
the QT-2100. Reading this section provides a general understanding of the overall system
of the QT-2100.
2-1. General description of application system
2-1-1. File concept
Programming data for each function, as well as registration data, are assigned and handled
in the RAM of the QT-2100 in data blocks called files. Each files identified by a 3-digit
file number, and consists of multiple records that affect the length and data format of the
file. The QT-2100 stores the location in RAM for each file in a work area, and specification
of a data location for accessing is accomplished using the file number, record number and
record format.
Memory management on a file basis allows flexibility memory allocation in accordance
with the application of a specific terminal and its memory capacity. The number of records
per file can be programmed, and a file can even be programmed for zero records.
There are three types of files:
– Terminal files:
Terminal files include system work files, daily total files, periodic total 1 and periodic
total 2 files. Periodic total files have only totalizer field, and totalize the same data which
is accumulated to terminal files at the same time. The periodic total 1 files have 100
order file numbers, and the periodic total 2 files have 200 order file numbers.
These files can be reset individually and separately from the terminal files. This
provides access to weekly and monthly total data. The periodic total 1 files and 2 files
have the same functions, and can accumulate data with different periods. The same
number of records as the corresponding terminal file must be reserved for each periodic
total files.
– Consolidation files:
Consolidation files are work files for consolidation of daily total, periodic 1 total and
periodic 2 total data from each terminal, and have 300, 400 and 500 order file numbers,
respectively. The same number of records as the corresponding terminal files must be
reserved for each file, on the master terminal.
– Consolidation work files:
Consolidation work files are work files for collection/consolidation of daily, periodic
1/2 data from each terminal. The files have 600 order file numbers.
The file number of records as the corresponding terminal file must be reserved for each
consolidation file.
Each file requires an internal work area, so calculation of actual file size can be performed
using the following formula:
Record length × Number of records + Work area = Actual file size
The following table shows all the files available for QT-2100. See the Appendix A-3 of this
manual for detail formats of individual files.
