Software Conversions - Program Structure Chapter 2

In Step 5, OB1 is the first code executed. In RSLogix 5000 software, the first

routine executed can be selected by the programmer. It is indicated in the

project tree by the icon beside the Main Routine. When converting a PLC

application from Step 5 to RSLogix 5000 software, function calls originally in

S5 OB1, are commonly placed in the designated RSLogix 5000 Main Routine.

The following window shows how routines appear under the continuous task

in the RSLogix 5000 project tree. The Main Routine designated as the start-up

routine is indicated by the icon .

The following example shows how three PBs called in from OB1 could be

converted into RSLogix 5000 software.

In S5 the PBs are given symbol names and called from OB1. In RSLogix 5000

software, the routines are called from the Main Routine.
