Diagnostics data and alarms
Diagnostic data and interrupts - overview
Diagnostics data contains important information about the status of SIMOCODE pro. This
information simplifies troubleshooting.
Unlike cyclic data, the diagnostics data is only transmitted to the master module if it changes.
PROFIBUS DP differentiates between:
● Standard diagnostics
● Status information
● Channel-related diagnostics
● DPV1 process and diagnostic interrupts.
Configuring diagnostic response
In SIMOCODE pro, you can set which diagnostic events trigger the transmission of
diagnostics data or interrupts to the PLC:
● Diagnostics for device faults, e.g. parameterization errors, hardware faults
● Diagnostics for process faults:
In the case of events identified as "S" in the column headed "DP diagnostics" in the "Data
record 92 - Diagnostics" table, the diagnostics data or interrupts are transferred to the
PLC.
● Diagnostics for process warnings:
In the case of events identified as "W" in the column headed "DP diagnostics" in the
"Data record 92 - Diagnostics" table, the diagnostics data or interrupts are transferred to
the PLC.
● Diagnostics for process events:
In the case of events identified as "M" in the column headed "DP diagnostics" in the "Data
record 92 - Diagnostics" table, the diagnostics data or interrupts are transferred to the
PLC.
