13.4.1 Error buffer
SIMOCODE pro has an error buffer in which the 21 most recent errors / faults and "Power -
On" events are recorded with a time stamp. Time stamps are based upon the operating
hours of the device (resolution 1 s), i.e. the length of time for which the device is supplied
with control supply voltage.
The "Error/Fault" and "Power - On" events are logged. Each of these events is given a time
stamp.
● Error/Fault: The last 21 errors are stored in a ring buffer; 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.
This data is displayed via the "SIMOCODE ES (TIA Portal)".
