4.2 DVP-SV3/SX3 Series
4.2.1 DVP-SV3/SX3 Hardware Framework
The DVP-SV3/SX3 series programmable logic controller is a small programmable logic control (PLC). The
execution speed and memory capacity are increased. Use of function blocks is also supported. In order to
meet more advanced application requirements, the DVP-SV3/SX3 series programmable logic controllers
provide more flexible system extension framework. Under such hardware framework, you do not need to use
several CPU modules to control the system if there are excessive I/O points or the device is too far away. This
new hardware framework maintains the integrity of the system and allows users to work more efficiently during
the project development process.
The minimum framework of the DVP-SV3/SX3 series system consists of one CPU module (DVP-SV3/SX3
PLC CPU) and one power supply module (DVPPS01 /DVPPS02/DVPPS05). The power supply module
converts AC into DC, providing PLC CPU with direct current power supply. A CPU module is the nucleus of a
complete DVP Series system. It is responsible for controlling and managing the whole system. DVP Series
PLC CPU provides various business sectors with several types of CPU modules. Select a CPU module
according to your needs.
Example of a minimum framework: power supply module (on the left side of the PLC CPU) and DVP-SV3/SX3
CPU module (the example below uses DVP28SV3)
