Operating data recording
The first column in the table contains a set temperature range. The columns contain the
individual counters for operating states and transitions. In principle, SMM stands for "device
has voltage supply" and CPU for "device is on and running".
Time indicates the total duration of the operating state in the temperature range in seconds.
The time for which the device had a voltage supply (SMM-Time) or was switched on
(CPU-Time). Example: CPU-Time = 716643.
The device ran for a total of 716643 seconds = 8.3 days.
Note
As each device that is switched on also has a voltage supply, the "device switched on and
running" (CPU) operating state times are always recorded simultaneously on the CPU- and
SMM- counters.
PwrCycles shows how often the device switched to this operating state. How often was
voltage applied to the device in the temperature range (device connected, SMM-PwrCycles)
and device switched on (CPU-PwrCycles).
Entries shows how often the device switched to this temperature range for each operating
state. Example: How often did the device switch to the temperature range while there was
voltage at the device (SMM-Entries) or the device (CPU-Entries) was running.
Note
PwrCycles and Entries adjust the data under Time in a temperature range. Example: Where
the total operating time Time = 1000 seconds and PwrCycles = 10, the device was only in
the operating state for an average of 100 seconds. Where the total operating time
Time = 1000 seconds and Entries = 10 in the "LOW temperature range, the device was only
in the "LOW" temperature range for an average of 100 seconds.
Heater-Time shows how long the heater was running in the respective temperature range.
USB backup of data displayed
Requirement
● A SIMATIC IPC USB flash drive is connected.
● The SIMATIC IPC USB flash drive has sufficient free memory space.
The following procedure should only be followed for servicing:
1. Insert the SIMATIC IPC USB flash drive into the USB port in the device.
2. Click on the "Export data to USB-Device" button.
3. After the export, the message "Export completed" appears.
All device data and operating times are saved.
