If a mistake is made, press Delete to delete the last entry in the IF statement.
Enter Logic Action: To enter a logic action, press Go to Then if the THEN part of
the statement is not already selected. Rotate the control knob to display the action
categories and press Select to display the specific actions for that category. Select
an item from the list of actions and press Insert to add the action to the THEN
portion of the logic statement. Press Done to complete the action portion of the
logic statement. Only one action is possible per logic statement.
When exiting the Edit Logic Statement screen, the statement is tested for proper
syntax. If there is an error, the operator is prompted to correct the error.
If the error is not corrected, the logic statement will always evaluate as false.
In addition to listing the 32 logic statements, the Logic menu displays the current
state of each statement. Statements in green are currently true. Those in red are
false. This can be an aid for troubleshooting logic statement and digital I/O
problems.
3.12.2.2 Logic Statement Conditions (IF)
Operators: For more complex logic statements, logical operators such as AND,
OR, NOT, parentheses ( ), greater than >, and less than < can be added.
Parenthesis are used to group logic conditions, for example, IF (Input1 AND
Input2) OR Input3. Every open parenthesis must have a matching closed
parenthesis. The less than (<) and greater than (>) operators are used only with
Timer conditions.
Numeric Values: Any integer between 1 and 64133. Numeric values are used with
timer conditions, for example, IF Timer1 < 100 THEN Relay1.
Inputs: Choose the logic state (active state) of one of the SQC-310 digital inputs
as a condition. If the specified input becomes active, the logic statement will
become true (choose input 1 to 16.)
Relays: Choose the logic state (active state) of one of the SQC-310 relays as a
condition. If the specified relay becomes active, the logic statement will become
true (choose relay 1 to 16).
SoftNodes: SoftNodes allow the building of logic statements that are based on
other logic statements. There are 8 SoftNodes available for use.
For example:
IF (Input1 AND Input2) OR Input3 THEN SoftNode1
The SoftNode can then be used as a condition in another logic statement.
If (SoftNode1 AND CrystalFail) THEN Stop Layer
Timers: The timer condition is evaluated true whenever the timer value is greater
than the value entered in the timer condition. There are 8 timers available for use.
