Variable and fixed
pocket coding
December 2001
You can work with either variable or fixed pocket coding.
7 7 7 7
Specify with MP7480 whether the tool or pocket number is to be
transferred to the PLC:
• Variable pocket coding: Pocket number must be transferred. Set
MP7480.x = 3 or 4.
• Fixed pocket coding: It is advisable to work with the tool number. Set
MP7480.x = 1 or 2.
Depending on the setting of MP7480.x, the NC transfers either only the
number of the programmed tool to word W264 or the tool and pocket number
to W262 and W264. The NC sets M4073 (TOOL CALL) or M4074 (TOOL DEF).
The strobe markers are not reset until you have set M4093 (TOOL CALL) or
M4094 (TOOL DEF) after the tool or pocket number, respectively, have been
processed. After you have reset the strobe marker, the NC program is
resumed (only with TOOL CALL).
If a TOOL CALL block is followed by the output of a T strobe and G strobe,
then M4547 is set by the output of the T strobe and reset by output of the G
strobe. If there is no output of either the T or G strobe, M4547 is not set.
If the tool number zero is processed, the NC sets marker M4521. The marker
is not reset until there is a TOOL CALL for another tool.
