Configuring a Controller
372 SPU 780 01EMAN May 2002 87
Editing Opcodes An opcode is a unique number identifying a loadable in the controller or project.
Because each opcode must be different, they may need changing.
When a loadable is added to a project or controller, the configura tor will compare the
new loadable’s opcode with the opcodes already used in the controller by built-in
instructions and previously loaded loadables. If it sees tha t the new lo adable opcode
will conflict, the Select Opcode window appears.
However, if you happen to know an opcode that won’t conflict with the loadables
already in your controller you can use the Edit Opcode option i n the wizard to m ake
the change. Then when you add the loadable in configuration, you won’t be
prompted to provide a new opcode.
