I am programming a small project using a GE RX3i. It is a process system so I am writing a few blocks using their structured text editor. Does anybody know if it is possible and what is the syntax for declaring variables (Inputs, Outputs) in the body of the structured text code in a manner similar to Siemens SCL? I continue to use their pop-up box to enter variable declarations. It is great for one or two blocks but it is easier to cut and paste using a plain text editor such as Boxer. Thank you.
