USIO21 Mass Storage Unit

In terms of hardware structure, the USIO21 is characterised by its combination of the advantages of a PC with a high-performance CPU and a large-capacity memory unit and a PLC with a modular structure. Modular plug-and-play structure, which can be electrically plugged and unplugged. USIO21 has a fully modular plug-and-play structure, which can be safely and conveniently electrically plugged and unplugged at industrial sites;

USIO21’s CPU and I/O modules are compact, small in size, with dense wiring terminals, and have perfect and exquisite design in many aspects such as module power supply and working status display etc. USIO21’s CPU adopts multi-processor structure and is equipped with high-capacity storage unit. USIO21, in addition to its high-performance main CPU, is usually configured with two other processors, i.e. three processors on the CPU module of a PCC.

The USIO21 maximises the processing power of the system. 6DD1683-0BC5 Inside the core computing module, the USIO21 equips its CPU with a mass storage unit (100K-64MB) that is several times larger than that of a conventional PLC, which undoubtedly provides effective hardware support for the powerful system software and application software.The USIO21 adopts a plug-in CF card as the storage medium.The USIO21 uses an insertable CF card as the storage medium, and the maximum storage capacity is up to 8GB.
