Keyword Explanation
User program In principle, a D4x5 user program can run on a D4x5-2, however, adaptations may be
required because of innovations in the hardware. Examples:
• The non-volatile data is backed up permanently and maintenance-free for the D4x5-2
(backed-up SRAM for D4x5); a buffer failure signaled via
persistentDataPowerMonitoring.powerFailure = "YES" therefore only applies to the real-
time clock, not for the non-volatile data.
• The runtime behavior of the D4x5-2 modules changes because of the increase in
performance. As long as the user program does not contain any "runtime-dependent
code", adaptations should not be necessary.
• The D4x5-2 has a double fan module. The user program must be adapted in order to
profit from the advantages of a double fan compared with a single fan (identification of
required maintenance). See Section Overview of the fan/battery module states
(Page 108).
• The user progr
am will have to be modified with respect to detection of the maintenance
case for D425-2/D435-2 if D425/D435 was used without a fan/battery module. See
Section Overview of states, fan/battery mod
ule (Page 108).
• The batterynecessary and fannecessary system variables have different states
depending on the device. See
– Section Operations and their effect on the user memory (Page 94) and
– Section Cooling the SIMOTION D4x5-2 (Page 106)
• As of SIMO
TION V4.3, the following additional functions are available for the D4x5-2:
– System variables rtcFailure and retainDataFailure
– Backup of the non-volatile SINAMICS data (NVRAM data) via CU parameter p7775
– Automatic detection of a module replacement on the basis of the serial number of the
Control Unit
Hardware The following changes have been made because of the hardware innovations:
• CompactFlash card under a cover (previously open access)
• Additional and slightly differently arranged operator control and display elements
• Modified connectors (larger cable cross-section, screw connection on the 24 V terminal
block, etc.)
• D445-2 DP/PN and D455-2 DP/PN have a heat sink so that the spacers (with the
exception of external heat dissipation) cannot be disassembled as for the D445-1. See
also Section Mounting a SIMOTION D4x5-2 (Page 27).
• A doub
le fan/battery module is always required for D4x5-2 Control Units. See Section
Cooling the SIMOTION D4x5-2 (Page 106).
• Contro
ller extensions (CX) for D4x5 can only be used for the D435 and D445/D445-1;
with the D4x5-2, all Control Units support the use of CX32-2 controller extensions.
