What are the customer benefits?
calls OB 72 on further events:
• The R/H-system has entered RUN-Redund­
ant system state and the synchronization of
the two R/H-CPUs is possible redundantly.
• The R/H-system has entered RUN-Redund­
ant system state, but the synchronization
of the two R/H-CPUs is not possible redund­
antly.
• 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
redundantly.
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 control
a SINAMICS drive cyclically with the technology
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.
What are the customer benefits?
The "Switched S1 device" function of the CPU
enables operation of standard IO devices in the
S7-1500R/H redundant system.
You mount the R/H CPUs on a standardized
35 mm rail using the standard rail adapter.
