Entering SFC macro-steps

A macro step is a special symbol that represents, within a SFC chart, a part of the chart that begins with a step and ends with a step. The body of the macro-step must be declared in the same program. The body of a macro-step begins with a special "begin" step with no link before, and ends with a special "end" step with no link after. The symbol of the macros step in the main chart has double horizontal lines.

Use the following buttons of the SFC toolbar for entering macro-steps:

Insert a macro-step

Insert the body of a macro-step

Important note: The symbol of the macro-step and the beginning step of its body must have the same number. Hit Ctrl+ENTER when a macro-step symbol or a beginning step is selected to change its number.
