If you work with one magazine, you must specify the type of pocket coding
for this magazine:
Set MP7482 = %0000.
Specify with MP7480.x 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: Working with the tool number is preferred. Set
MP7480.x = 5 or 6
If you work with more than one magazine, you must specify the type of
pocket coding for each magazine individually:
Set MP7480.x to 3 or 4 for variable pocket coding.
Define in MP7482 the type of pocket coding for each magazine.
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.
After the acknowledgment marker for an NC strobe is set (e.g. Marker M4093
for T strobe), the corresponding strobe marker (e.g. Marker M4073) is not
reset (= 0) by the NC software until the NC has actually concluded the actions
immediately triggered by acknowledgment of the strobe. This makes it
possible for the PLC program to know when this processing by the NC is
actually concluded. For example: renewed access to the pocket table only
once pocket exchanging by the NC has concluded. The behavior of the strobe
markers can be configured with bit 16 of MP4020.
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.
With MP7483 you specify if the tool name or tool number or both can be used
for TOOL CALL or TOOL DEF. For example, if a tool number is used, an NC error
message will be output if only tool names are allowed (MP7483 = 1).
