5.5.6 Call Extended Program (XCALL)
( 1 ) Operation
An extended program (i.e., a table program, such as a constants table, an I/O conversion table, an interlock table, or a
part composition table) is executed. The MPE720 converts the extended program into a ladder program. Converted lad-
der programs can be executed with the XCALL instruction.
Although more than one XCALL instruction can be used in a single drawing, the same extended program cannot be
called more than once.
( 2 ) Format
∗ I/O conversion tables, interlock tables, and part composition tables are not supported by MPE720 version 6.
Use MPE720 version 5 if you have created these types of tables.
( 3 ) Programming Example
This example shows how to call an MCTBL constants table.
