then it must be released again.

Up to four different tool magazines can be managed in the pocket table. In the

pocket table the tool magazines are listed from 1 to 4, i.e., first tool magazine

1 with tool 1 to <MP7261.0>. Immediately thereafter, tool magazine 2

appears with tool 1 to <MP7261.1>, then tool magazine 3, etc.

Enter the number of pockets in tool magazines 1 to 4 in MP7261.0 to

The current tool magazine number is saved in W268.

Module 9302 searches for an open pocket in a tool magazine, and Module

9306 switches tools between the tool magazines.

Module 9301 determines the number of the entry in the pocket table. The

number of the entry depends on the tool magazine and pocket numbers.

Enter this number in the modules which cannot accept tool magazine

numbers (e.g. Modules 9092, 9093, 9094).
