PROFINET, MES address maintenance issues
PROFIBUS International has released the “PROFINET and MES Maintenance Operations” guideline, which describes interface functions that support MES maintenance systems. According to an article from PROFINET International titled “PROFINET and MES: Closing The Communication Gap,” the guideline facilitates consistent communication with PROFINET from the field level to top management, making it easier to switch from predictive maintenance to condition monitoring in machines and systems.
Although MES/ERP interfaces are defined in ISO/IEC 62264, PROFINET’s new specification defines an open interface between MES and automation systems for maintenance operations. This means that standardized interface functions are now available between PROFINET and the MES maintenance field.
The article states that the standard also provides suitable mechanisms for PROFINET to identify devices used in the system electronically. Device manufacturers would save an‘electronic type plate’ within the devices. This information could be beneficial to end users who could use the information for device maintenance or asset management functions.
