The response speed of the 1326AB-B520E-M2L is not only determined by the CPU, but is also related to the I/O data transfer rate.The main CPU of the PCC itself is extremely fast, and at the same time borrows the structure of a mainframe computer, adopting the I/O-Processor to handle I/O data transfer separately, and adopting the DPR-Controller bi-directional port controller to be in charge of network and system management. The DPR-Controller is responsible for network and system management. In other words, there are three processors on one PCC module, which are independent and interrelated, maximising the speed of the whole system.

The 1326AB-B520E-M2L is the highest-performance product in the X20 CPU series, which adopts the Intel Celeron 650 processor and additional I/O processor and floating-point processor FPU, and the system’s single-step instruction processing cycle time can be as fast as 0.01 μs, and the cycle time of a single task can be as high as 200 μs, which is the world’s most powerful and fastest PLC/PCC CPU. It is one of the most powerful and fastest PLC/PCC CPUs in the world.
