Chapter 11 Motion Control in PR Mode
When in PR Mode, the Statement type allows you to define an expression, then
evaluate the logical output of the PR once the Expression executes and the
Procedure statement is evaluated. The Statement type only executes once and
must have the Servo On signal true. The Statement type only operates within
the PR programming environment. For example, if you initiate a Jog Forward
command by using the Digital Input, the Statement PRs do not execute in
parallel. The Statement type (like other PRs) executes once the initial PR is
selected (by using Digital IO) and the Command Triggered Digital Input
transitions ON.
Statement Type Characteristics
• Statements are executed once (the statement does not continuously
evaluate; unless a JMP statement is used)
• Statements only operate while the drive is enabled
