What are the customer benefits?
As of FW version V2.9, the operating system
calls OB 72 on further events:
• The R/H-system has entered RUN-
Redundant system state and the synchro-
nization of the two R/H-CPUs is possible
redundantly.
• The R/H-system has entered RUN-
Redundant system state, but the synchro-
nization of the two R/H-CPUs is not possi-
ble redundantly.
• The R/H-system is still in RUN-Redundant
system state and the synchronization of
the two R/H-CPUs is possible redundantly
now or again.
• The R/H-system is still in RUN-Redundant
system state, but the synchronization of
the two R/H-CPUs is no longer possible re-
dundantly.
As of FW version V2.9, the "RH_CTRL" instruc-
tion supports additional functions:
• Request SYNCUP
• Switch primary CPU to STOP mode (only in
RUN-Redundant system state)
• Switch backup CPU to STOP mode
As of FW version V2.9, instructions for the
recipe functions are supported:
• RecipeExport (Export recipe)
• RecipeImport (Import recipe)
"TO_BasicPos" technology object
With the "TO_BasicPos" instruction, you con-
trol a SINAMICS drive cyclically with the tech-
nology for SINAMICS S/G/V basic positioners.
SSI_Absolute_Encoder technology object
With the "SSI_Absolute_Encoder" instruction,
you use the user program to control the posi-
tion detection and measuring functions of the
TM PosInput technology object.
