15.5.3.4 Vision Sensor alarm
A PROFINET diagnosis alarm is triggered by the Vision Sensor for certain errors. An error code (a 32 bit
value) is then transmitted. It is possible for multiple alarms to be triggered simultaneously.
The alarms are reset once the source of the error has been rectified.
Error code Error description
Bit 0
Data buffer overrun: The amount of data produced by the Vision Sensor (e.g. result data) is larger than
can be received by the module intended.
Bit 1
Pipeline overflow: The internal buffer for data output is full, the data was sent too slowly via PROFINET
(or not at all).
Bit 2
Handshake error: The handshake mechanism was not used correctly, e.g. acknowledgement without a
corresponding request being sent.
