18 (informative)Signal Mapping
Signal Mapping
In the past, machine tool builders typically provided legacy interfaces defined by leading customers in a similar way. Often these interfaces were quasi-standardized as they were integrated in the PLC libraries of the leading control manufacturers. The signal names were often the same.
The following table gives an overview how the standardized variables of OPC 40501-1 could be mapped to these legacy signals.
| Legacy Signal | Variables defined by OPC 40501-1 v1.00 | Additional variables defined by OPC 40501-1 v1.01 |
| Number of total parts | (Not identical to legacy signal) ProductionStatisticsType/ PartsProducedInLifetime |
ProductionJobType/
PartsCompleted |
| Number of good parts | (Not identical to legacy signal) the information to each part ProductionPartType/ PartQuality |

| Number of scrap parts | (Not identical to legacy signal) the information to each part ProductionPartType/ PartQuality | Can be calculated directly from

OPC 40501-1 Job Management to OPC 40001-3 Job Management
With version 1.02 of OPC 40501-1, the job management with ProductionJobListType and ProductionActiveProgramType is deprecated. The job management for machine tools is intended to use OPC 40001-3 exclusively in the future.
The following table tries to map the previous 40501-1 variables to the OPC 40001-3 variables. Please note that the general idea for representing jobs, programs and parts in 40501-1 differs from the concept of OPC 40001-3 with job orders, work masters and OPC UA Structures for JobOrderParameters and JobOrderResults.
Most of the table’s contents are derived using section 7 and Annex B.2 of OPC 40001-3.
