8 OPC UA ObjectTypes

8.3 Monitoring

8.3.10 ChannelModifierType

The ChannelModifierType allows to show which modifiers are used while the machine tool is performing pre-production tests and similar tasks.

The ChannelModifierType is formally defined in Table 25.

0:HasComponent	Variable	BlockSkip	0:Boolean	0:BaseDataVariableType	O, RO
0:HasComponent	Variable	DryRun	0:Boolean	0:BaseDataVariableType	M, RO
0:HasComponent	Variable	OptionalStop	0:Boolean	0:BaseDataVariableType	M, RO
0:HasComponent	Variable	TestMode	0:Boolean	0:BaseDataVariableType	O, RO

BlockSkip being True indicates that specially marked NC program blocks are skipped.

DryRun being True indicates that a test run using with a dedicated axis feed is being performed.

OptionalStop being True indicates that the execution will stop at special machine commands.

TestMode being True indicates a test mode which enables execution of a program without physical axis movement. The machining process may be simulated during program execution.

SingleStep being True indicates if the NC channel operates in single block/single step mode.
