Fb 172 Wz-T-Nr Tools Selected According To T Number - Siemens SINUMERIK 840 Planning Manual

01.91
9.2.12 FB 172 WZ-T-NR
Tools selected according to T number
Description
FB 172 initializes the display "Selected tools" with display parameters. The block determines
the required tool in the magazine assignment via the T number entered.
The block first deletes the selection buffer and then selects the tools via the T numbers and
copies them into the selection buffer. DBs 183 to 189 are required as selection buffers (length
= 50 words); they are generated by FB 161 at a cold restart.
The block first searches the buffer and afterwards all chained magazines from the magazine to
be loaded onwards. The following message appears if more than 50 tools are found:
"Selection buffer full!".
If an error occurs during processing, a user-specific text is output together with the
corresponding error message.
