The M code group check function checks if a combination of multiple M
codes (up to three M codes) contained in a block is correct.
This function has two purposes. One is to detect if any of the multiple M
codes specified in a block include an M code that must be specified alone.
The other purpose is to detect if any of the multiple M codes specified in
a block include M codes that belong to the same group. In either of these
cases, P/S alarm No. 5016 is issued.
For details on group data setting, refer to the manual available from the
machine tool builder.
Up to 500 M codes can be specified. In general, M0 to M99 are always
specified. M codes from M100 and up are optional.
Group numbers can be set from 0 to 127. Note, however, that 0 and 1 have
special meanings. Group number 0 represents M codes that need not be
checked. Group number 1 represents M codes that must be specified
alone.
