Read Data From Data Table
Using a Table Code Q0~Q31 (V, Z index modiable) or a Table Nickname (by user-dened 16 English characters)
S1 : the Table Code or Table Nickname of the
data table
S2 : the initial address number at the table to
be read
D : the initial register ID number to store the
read data
n : the length of the data to be read
(Unit: word)
This instruction in the VS Series PLC reads the specic data from the data table. And then, stores the data into
given Data Registers to provide as the reference source for program operation.
When X20 = “OFF” → “ON”, it will execute to read a group of data at the addresses 0~99 in the
_
“FORMULA TABLE” and put the data in D1000~D1099. Due to the = 100, it will read a group data that
contents with 100 words.

At the previous VB series PLC, it has the File Register. Usually, the user can preset a huge number of data in the
File Register and while the status of the PLC turns from STOP to RUN the system will duplicate the contents from a
block of the File Register to the specic general registers automatically. That is very useful for the machine's
parameters or reference data.
Compared with that, the VS series substitute the File Register to the Data Table to store a huge of preset data for
the parameters and the reference data. The new structure of Data Table can have many tables and be named for
each purpose. It has the advantage about easy to manage and access.
The Data Table is established by the programming tool Ladder Master S, it is a part of the project. Therefore, when
the project is installed to the PLC, all the Data Tables will be copied together.
