Properties and technical specifications of CPU 410 SMART
17.1 CPU 410 SMART
CPU 410 Process Automation/CPU 410 SMART
284 System Manual, 05/2017, A5E31622160-AC
The integrated main memory of the CPU 410 SMART is 8 MB; 4 MB for programs and 4 MB
for data. This size of the load memory is 48 MB.
The CPU 410 SMART does not support any delay alarm OBs (OB 2x) or any associated
SFCs 32, 33 and 34. If you call one of these SFCs in the user program, it is not executed. An
error message is created instead and OB 121 is called.
If a SFC is assigned to a time-delay interrupt and downloaded to the CPU 410 SMART, the
SFC is not executed. An OB request error is reported when the configured time has elapsed.
The CPU 410 SMART supports the following cyclic interrupt OBs:
● OB 32 with a default run time of 2000 ms
● OB 33 with a default run time of 1000 ms
● OB 34 with a default run time of 500 ms
● OB 35 with a default run time of 200 ms
You cannot set a phase offset.
The CPU 410 SMART does not support hardware interrupt OBs (OB 4x). If you assign a
SFC to a hardware interrupt and download it to the CPU 410 SMART, the SFC is ignored.
If you have nevertheless enabled hardware interrupts on I/O modules with interrupt capability
and a hardware interrupt is generated, it is merely entered in the diagnostics buffer and the
SFC is not executed.
