List of operands
Operand Description
PBn Global PB number (1000 to 1999)
■
Outline of operation
● A fixed PB number can be used for the global PB number, even if the PB position is
changed.
● This instruction should be described at the beginning of a main program area.
● This instruction sets an active PB number to a specified global PB number table in the
preprocessing of operation (when switching PROG to RUN, during rewriting during RUN).
● When multiple GPB instructions are described in the same PB, multiple global PB numbers
are set for one PB.
● The range of PB numbers that can be specified for instructions that use PB numbers
(ECALL, EFCALL, LCWT, LC, STARTPG, and STOPPG) is as follows:
PB number specification: 1 to 468
Global PB number specification: 1000 to 1999
● A syntax error occurs when a number (other than 1000 to 1999) that is out of the range of
the settable global PB numbers is specified by the GPB instruction.
● An operation error occurs when a global PB number that is not set is specified for an
instruction that uses a PB number.

Sample program
Example 1) Example when using GPB
PB1 declares the global PB number 1000 for own PB, and calls the subroutine for GPB1000
from PB2.
