Error Buffer/Reading Out Error Protocol - Siemens SIMOCODE pro System Manual

14.4

Error buffer/reading out error protocol

Timestamping in the error buffer is based on the operating hours
(resolution: 1 s) of SIMOCODE pro.
The "Error/Fault" and "Power - On" events are logged. Each of these events is
given a timestamp.
• Error/Fault:
The last 21 errors are stored in a ring buffer, whereby the incoming error
(rising edge) is always logged. An outgoing error (falling edge) will not be
logged.
• Power - On:
If the most recent entry is "Power - On", this is not logged multiple times.
Instead, the error number is used as a power on counter. Thus, the error
buffer cannot be deleted by frequent on/off operations.
Entry 1 is the most recent entry and entry 21 the oldest.
The data will be displayed via the "SIMOCODE ES" software.
Example:
Fig. 14-4: Example of event logging using the "SIMOCODE ES" software
SIMOCODE pro has an error buffer, in which the 21 most recent errors/
faults, "Power - On" events" are recorded with a timestamp. Timestamps are
based upon the operating hours of the device (resolution 1 s), i.e. the
amount of time that the device is supplied with control supply voltage.
