Up to 8192 inputs and outputs
The CPU types Q02(H) to Q25H, the universal model CPUs from
Q03UD(E)CPU on, all process CPUs and redundant CPUs can address up
to 4096 in/outputs directly on the base unit. Together with remote
I/Os these CPUs can address up to 8192 I/O points.
A Q02UCPU can address up to 2048 in/outputs directly and up to 8192
I/Os totally.
The Q00JCPU and Q00UJCPU address 256 I/O points directly. The
Q00CPU, Q00UCPU, Q01CPU or Q01UCPU addresses 1024 I/O points. With
these CPU types the number is extended to 2048 points and to 8192
points with the universal model PLC CPUs by remote I/Os.
High speed program processing
CPU types with an additional "H" (like Q12HCPU, Q25HCPU or
Q12PHCPU) do a faster processing of the program. The operation time
for the LD instruction (load) by the Q02CPU is 79 ns. The same
instruction is done in 34 ns by the H type CPU.
An universal model PLC CPU increases the processing speed
additionally. The operation time of the above mentioned LD
instruction takes only 20 ns with the Q03UDCPU and only 9.5 ns with
CPU modules from Q04UDCPU on.
Overall configuration
Following figure shows the system configuration for a Q00JCPU or
Q00UJCPU using a combination of main base unit, CPU and power
supply module.
