Purpose DO
DI mapping should be assigned 1 group = 16 byte mapping and DO
mapping should be assigned 1 group = 8 byte mapping. The reason is as
follows.
MPG interface(the counter for MPG) uses Xm+12 to Xm+14 area and it
is fixed. And if MPG interface will be used, Xm+12 to Xm+14 area must
be assigned. therefore, in case of i series and using MPG interface, DI
mapping must be assigned 16 byte mapping. MPG counter area are
directly processed by CNC software. So you must not use this area by
customer ladder.
It is possible to assign any address for this operators panel. But in DI
address, each CNC have some fixed address that is directly processed by
CNC software. So, as refer to the following mention,assign the DI
mapping.
