Base units
The Q00JCPU and Q00UJCPU include power supply,CPU and main base unit with five slots.
All other CPUs have to be mounted on a main base unit. Additionally one or two power supplies
can be mounted and up to twelve modules.
Extension base units can be connected to the main base unit via bus cable. The extension base units are available with or without slots for a separate power supply and with slots for up to twelve modules.
The Q00JCPU and Q00UJCPU can adress max. 16 modules on one main base unit and two
extension base units.
The CPU modules Q00CPU, Q01CPU, Q00UCPU, Q01UCPU and Q02UCPU are extendable with up to four extension base units and totally 24 modules (36 modules with Q02UCPU).
Except for Q12PRHCPU and Q25PRHCPU, all other CPU types can be extended with seven extension base units with maximum 64 slots total. The maximum distance between main base unit and last extension base unit is 13.2 m, so that the base units can be mounted inside the cabinet with some distance between each other.
- Connecting extension base units to a redundant PLC system
It is not possible to connect an extension base unit to a main base unit with a redundant CPU up to serial no. 09012... The expansion can be done by remote I/O station via MELSECNET/H network.
It is possible to connect a main base unit with a redundant Q12PRHCPU or Q25PRHCPU beginning at serial no. 09012... up to maximum seven extension base units with totally 63 modules.
The first extension base unit must be the type Q65WRB, the second to seventh unit can be of type Q68RB.
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.
With the new MELSEC System
Q main base units with integrated memory and processor the data transfer to I/O modules, intelligent function modules and network modules is much faster compared to the previous base units. The access of the Q02HCPU to an intelligent function module is with 20 μs per word 7 times faster than with the Q2ASHCPU. The refresh cycle of the MELSECNET/10 network is around 4.3 times faster compared to the Q02HCPU and needs only 4.6 ms for 8 kwords.
