Some problems plc cpu modules of

Drive in function provides a variety of fieldbus communication module , is ideal for system integration applications , parking facilities and remote monitoring applications ; built-in PLC function can Nanda plc controller suppliers  replace the small single-chip controllers, counters and timers , thereby significantly reduce system cost , which is very suitable for price-sensitive machining industry ; adopts European design , can hang side by side rails can be added back , compact body type can be significant savings in installation space ;
Meanwhile, the products do parallel DC bus powered , energy efficient mutual feedback absorbed , distributed braking resistor burden , and more than one use the same brake module , greatly reducing the Nanda plc digital input  system cost ; fully comply with export requirements.
In addition, the product can also be convenient and flexible range of optional accessories , such as I / O card , A / D, D / A module, digital operator , PG card , communication module, the customer may need a reasonable configuration , allowing the system to achieve best value for money ; perfect protection , high accuracy current sensing , are the highlights of its functions .
Drive only in product features, performance and  Nanda plc input output modules control technology are always inherited the advantages of automation Delta family , but also in the application point of view , a flexible modular design, environmental protection and energy saving aspects of innovation . But even more noteworthy is that , VFD-E series inverter built a powerful PLC 's

the transmission ratio by mechanical transmission components , to achieve the purpose of changing the

Which calculation plc cpu modules ten modules

CPU has the basic functions of the following four areas:

1 This refers to the sequence control instruction execution order control program instructions.

 There is between each instruction in Nanda plc IO module  the program's strict order, the order must be

 in strict accordance with the procedural requirements of the execution, in order to ensure the correctness 

of the computer work.

2 the function of controlling the operation of an instruction executed by a computer is often a component

 in a sequence of actions to achieve. CPU according to these instructions, to produce the corresponding

 operation control signals sent to the corresponding components to  Nanda plc program logic controller 

control these components according to the requirements of directive action.

3 Time Control Time Control is the timing of the implementation of a variety of operating time. During 

the execution of an instruction, and at what time to do what action should be strictly controlled. Only in 

this way, the computer can automatically work methodically.

4 data encryption for data that arithmetic and Nanda plc input output modules  logical operations, or 

other information processing.
