Entering a value in the table
When the function block is active, the current value at the
double word input at TB..I1 is entered in the table every time
there is a rising edge at the WP coil. Coils TB..EN and TB..WP
can be actuated simultaneously with a rising edge.
Each new table entry is entered behind the previous one until
the sixteenth entry is reached. Immediately after the value of
TB..I1 is transferred, this value is output TB..QV. Output
TB..QN is incremented by 2 and then supplies the current
number of table entries.
If the maximum number of 16 table entries is reached, no
more data is transferred to the table and signal contact
TB..TF closes. If you wish to make more table entries, read
values from the table beforehand or clear the entire table
with a rising edge at the RE coil.
A rising edge at the RE coil causes:
• The value at output TB..QN to be set to 0.
• The signal contact TB..TE to close.
• The signal contact TB..TF to open.
Reading out the table
The TB..RF and TB..RL coils are used to control whether you
are reading out from the start or end of the table.
A rising edge at coil RF (Read First) clears the first table entry
(FIFO function) and supplies it at output TB..QV.
A rising edge at coil RL (Read Last) clears the last table entry
(LIFO function ) and supplies it at output TB..QV.
With each output of a table entry the signal at output TB..QN
is reduced by 1.
