Siemens SIMATIC S7-1500 CPU 1511-1 PN

Article number 6ES7511-1AL03-0AB0
Update time for IRT 
–
for send cycle of 250 µs 250 μs to 4 ms; Note: In the case of IRT with iso
chronous mode, the minimum update time of
500 µs of the isochronous OB is decisive
–
for send cycle of 500 µs 500 μs to 8 ms; Note: In the case of IRT with iso
chronous mode, the minimum update time of
625 µs of the isochronous OB is decisive
–
for send cycle of 1 ms 1 ms to 16 ms
–
for send cycle of 2 ms 2 ms to 32 ms
–
for send cycle of 4 ms 4 ms to 64 ms
–
With IRT and parameterization of "odd"
send cycles
Update time = set "odd" send clock (any multiple
of 125 µs: 375 µs, 625 µs ... 3 875 µs)
