How to Use the Sequence Table Block Appendix B
Explanation
The TBL command in the main table inputs the condition evaluation result for the same rule column in the
specified reference table as the condition signal.
When Y is entered as the condition rule for the TBL command, the condition evaluation result is input in the ref-
erence destination as is. If N is entered, the input is inverted.
TBL Command Details
• When the TBL command is used in the main table, the condition contacts (ITEM 025 to ITEM 028) for the
TBL command are always 0.
• The reference table condition rules (ITEM 021 to ITEM 024) display the internally held evaluation results.

The Y indicates that the evaluation result
for the condition rule of the same number
in the reference table is input as is.
N indicates that the evaluation result for
the condition rule of the same number in
the reference table is reversed before
input.
Therefore, in this example, rule 1 specifies
that evaluation result Y is to be input as is,
so the reference result is ON (met). Rule 2
specifies that Y is to be input as is so the
reference result is OFF (not met).
