9.4 Message buffer

9.4 Message buffer
In addition to the fault buffer for F... faults and the alarm buffer for A... alarms (see the
relevant section in SINAMICS S120 Commissioning Manual), a special message buffer for
C... safety messages is available for Safety Integrated Extended/Advanced Functions.
The fault messages for the Safety Integrated Basic Functions are stored in the standard fault
buffer (see chapter "Buffer for faults and alarms" in the SINAMICS S120 Commissioning
Manual).
Note
Messages of the Basic and the Extended/Advanced Functions
Set parameter p3117 = 1 if you need to save both the Basic Functions messages and the
Extended/Advanced Functions messages in the standard fault buffer.
The message buffer for safety messages is similar to the fault buffer for fault messages. The
message buffer comprises the message code, message value, and message time (received,
resolved), the component number for identifying the affected SINAMICS component and
diagnostics attributes.
