11.3 Diagnostic Messages via Process Data
Besides the evaluation of diagnostic data via Explicit Messages, TBEN-L with EtherNet/IP™ offers the
possibility of mapping diagnostic data into the process data (see also the devices‘ process data
mappings (page 78 ff.).
2 different forms of diagnostic data handling are provided:
Summarized diagnostics
Scheduled diagnostics (manufacturer specific)
11.3.1 Summarized Diagnostics
The summarized diagnostic data mode will send back the bit "I/O Diag" which indicates that one of
the device channels sends a diagnosis.
This bit will be "0" if there are no diagnostic flags set on the device. This bit is set to "1" if there are
diagnostics pending.
Bit "I/O Diag"
0 = OK, no diagnostics present
1 = At least 1 channel sends diagnostics
11.3.2 Scheduled Diagnostics (Manufacturer Specific)
The scheduled diagnostics feature (Process Data Class (VSC102), page 93) is used for mapping the
channel diagnostic bits into the device's process data (siehe page 78) ff..
Bit "SchedDiag"
0 = no mapping of channel diagnostics into the process data
1 = mapping of channel diagnostics into the process data activated
11.4 QC - QuickConnect
QuickConnect enables a PLC to build up connections to EtherNet/IP™ nodes in less than 300 ms
after switching-on the power supply for the EtherNet/IP™ network. The fast start-up is necessary for
fast tool changing applications at robot arms for example in the automobile industry.
The TBEN-L-devices support FSU with a start-up time of < 150 ms.
Ethernet-Cabling for TBEN-L in QC-Applications
Please read Ethernet-Connection for QC/FSU Applications, page 27 for information about the
correct Ethernet-cabling in QC-applications with TBEN-L.
