PLS SETUP PROCEDURE

The following example demonstrates the set up of a PLS data structure.

	IMPORTANT
	The PLS data object must be defined in CONFIG.PRG: Common Shared <PLS Name> as PLS <Axis> System.Dout.<DOut number> For Example: Common Shared Demo_PLS1 as PLS A1 System.Dout.1

For a complete explanation about PLS please refer to PLS Software Specification.
