The non-volatile data of the SIMOTION D4x5‑2 has the following properties:
Table 5-2
Non-volatile data and real-time clock properties
Characteristics
Non‑volatile data
Real-time clock (RTC)
Location
The non-volatile data is located
● For a D4x5‑2 in an NVRAM
● For a CX32‑2 in an FRAM
The real-time clock is backed up main‐
tenance-free via a SuperCap or a bat‐
tery.
Back-up battery
No
Optional
(for longer backup time)
Backup time
There is no maximum backup time
● SuperCap: At least 4 days
● Battery: At least 3 years
If the buffer time is exceeded on the real-time clock, the time is reset.
Fan/battery module
If the backup time for the real-time clock (RTC) is not sufficient, a battery can be connected
by means of an external fan/battery module. The backup time when a battery is used is at least
3 years.
A 3 V lithium SN: 575332 battery type (with cable lug and connector) is used. The battery can
be replaced without data loss, because the real-time clock is backed up internally via the
SuperCap.
A fan/battery module is always required for SIMOTION D4x5-2 and therefore is always
supplied with the module (see the
SIMOTION D4x5-2 Manual).
CF card
The CF card contains the following data:
● SIMOTION Kernel (SIMOTION D firmware)
● Technology packages (TP)
● User data (units, configuration data, parameter settings, task configuration)
● IP parameters (IP address, subnet mask, router address)
● DP parameters (PROFIBUS DP address, baud rate)
It may also contain:
● User data saved with _savePersistentMemoryData and _export/_saveUnitDataSet
● SINAMICS non-volatile data (NVRAM data) of the SINAMICS Integrated or a CX32-2
backed up with CU parameter p7775 = 1
● Data from SIMOTION IT
● Archived SCOUT project
