How to Use the Sequence Table Block
• In the conditions half of the table, enter the input signal or relational expression's comparison result to be
used. Enter "Y" in the rule's cell to specify an ON condition or "N' to specify an OFF condition. Leave the
cell blank if the input signal or relational expression's comparison result is not used in the rule.
• In the actions half of the table, enter the output signal. Enter "Y" in the rule's cell to turn the output ON or
"N' to turn the output OFF. Leave the cell blank if the output is not operated by the rule.
Note Enter "Y" when the output is a non-holding or pulse output. ("N" cannot be entered.)
• When an ITEM write command is being used in the actions half of the table, enter the ITEM write com-
mand (destination ITEM and write data) in the signal column. Enter "Y" in the rule column if the ITEM will
be written by that rule. ("N" cannot be entered.)
• It is also possible to start another sequence table by specifying that sequence table's number (block
address) in the actions half of the table. (Execution of the local sequence table will continue and the other
table will be started.)
• Always enter step numbers in ascending order. (It is fine to skip step numbers.) When two or more rules
are being defined for a single step, enter the step number for the first rule; the step number can be omitted
for the remaining rules in the step.
• A destination step number can be entered in the last row of each rule.
THEN: Processing will switch to the specified step when the rule's condition is met.
ELSE: Processing will switch to the specified step when the rule's condition is not met.
• It is possible to verify a sequence table's action with the CX-Process Tool. (This function monitors variables
such as the step number being executed and whether conditions are met or not met.)
• When validating a sequence table for LCB05 Ver. 1.5 or later, the sequence tables can be edited online
while the Loop Controller and sequence table are operating. (Supported by CX-Process Tool Ver. 3.2 or
higher.)
• When validating a sequence table for LCB05 Ver. 1.5 or later, the PVs of elements (timers and counters)
are displayed. The SPs for the elements (timers and counters) can also be changed while the Loop Con-
troller and sequence table are operating. (Supported by CX-Process Tool Ver. 3.2 or higher.)
• When using LCB05 Ver. 3.0 or later, the table referencing function can be used. (Supported by CX-Process
Tool Ver. 5.0 or higher only.)
