Customizing the Model
3.8 Customizing the Model
Models can be customized using the ICAM macro language to perform special actions. The
sample MHERML50 model for example contains a startup macro that closes the front door at the
start of processing.
Model macros are not necessary for normal processing.
Model macros are called when certain events occur, to allow for any special processing needed
to keep the model up to date. Information about the event is passed to the model macro in the
form of $P variables. The following macro types are available:
� A Startup Macro is executed once at the start of
processing.
� A Shutdown Macro is executed once at the end of
processing.
� A Tape Event macro is executed each time a block
of tape (i.e., MCD) is processed.
� A Motion Event macro is executed each time the
model is moved.
� A Rapid Event macro is executed before a positioning
motion.
� A Feed Event macro is executed before all other interpolation
motions.
� A Load Tool Event macro is executed whenever the tool is changed.
Model macros share the same macro environment as the post processor or control emulator,
which gives them full access to system variables and user defined global variables. Model
macros are somewhat restricted in that they cannot generate post processor commands or call
matching macros that in turn generate post processor commands.
Model event macros and simulation function are described starting on page 122.
