2.2.12 Data Table Addresses (D)
PMC sequence control sometimes requires a sizable amount of numeric
data (hereinafter referred to as data table). If the contents of a data
table can be set or read freely, they can be used as various PMC
sequence control data, such as tool numbers of tools on the ATC
magazine.
Each table can have an arbitrary size as long as it fits the data table
memory, and 1-, 2-, and 4-byte binary and BCD data can be used for
each table separately; so it is possible to configure efficient, easy-to-
use tables.
Data in a data table can be set in PMC nonvolatile memory or displayed
via the DATA TABLE screen.
Data set in data tables can also be easily read and written with the
sequence program using functional instructions such as data search
(DSCHB) and index modification data transfer (XMOVB).
The following table lists the number of bytes that can be used.

(1) Data table configuration
The PMC data table consists of table control data and data tables.
The table control data manages the data form (binary or BCD) and
size of each table.
Creating a data table requires first setting up table control data
from the DATA TABLE CONTROL screen.
The sequence program cannot read or write the table control data.
If the Floppy Cassette is used to read or write the contents of the
nonvolatile memory, however, the table control data is read or
written together. Fig. 2.2.12 (a) roughly shows the configuration
of the data table. Fig. 2.2.12 (b) shows it in detail.
