Stage Programming

[nvpaul]

Thanks everyone who responded to my previous post. I believe I have found a good method to use to program this traveling saw. I am using stage programing with jump statements to wait for each state to complete. The only hangup I have now is how to initalize the process. If I simply use a set command with say an on button then the initial stage that the set command goes to would be scanned and activated every time the program is scanned. I have noticed that some Plc's have an initial stage that can be used but my Keyence doesn't. Any thoughts would be appreciated.

Use the keyence Instruction DIFU - Differention Up (commonly known as rising edge one-shot.)
