Abstract
The invention relates to a control system for an industrial robot adapted for storage of user programs which comprise a series of robot instructions. At least one of the robot instructions is arranged as a shell instruction, which constitutes a call to a shell routine (20). The shell routine is associated with a plurality of optional attributes (21a, 21b, 21c) and comprises PA1 - a forward list (22) comprising a first set of robot instructions; and PA1 - a backward list (23) comprising a second set of robot instructions. The control system comprises a program executor adapted, for forward running of a user program, to execute the shell instructions in accordance with the forward list and, for running the user program backwards, to execute the shell instructions in accordance with the backward list. The invention also relates to a method for controlling an industrial robot. The method comprises creating a plurality of shell routines and testing them in advance. When producing user programs, shell instructions are used which constitute calls to the shell routines created in advance. The user programs are executed by the program executor, and for forward running the shell instructions…
