TRICONEX 2658高性能可编程逻辑控制器

(1)从开关量控制发展到顺序控制、运算处理，是从下往上的;

(2)逻辑控制、定时控制、计数控制、步进(顺序)控制、连续PID控制、数据控制――PLC具有数据处理能力、通信和联网等多功能;

(3)可用一台PC机为主站，多台同型PLC为从站;

(4)也可一台PLC为主站，多台同型PLC为从站，构成PLC网络。这比用PC机作主站方便之处是：有用户编程时，不必知道通信协议，只要按说明书格式写就行;

(5)PLC网络既可作为独立DCS/TDCS，也可作为DCS/TDCS的子系统;

(6)主要用于工业过程中的顺序控制，新型PLC也兼有闭环控制功能。

(1) From the switch quantity control to the development of sequence control, operational processing, from the bottom up;

(2) logic control, timing control, counting control, step (sequence) control, continuous PID control, data control - PLC has data processing capabilities, communication and networking functions;

(3) A PC can be used as the main station, and multiple PLCS of the same type are the secondary station;

(4) A PLC can also be the main station, and multiple PLC of the same type can be the slave station to form a PLC network. This is more convenient than using a PC as the main station: when there is user programming, you do not have to know the communication protocol, as long as it is written in instruction format;

(5) The PLC network can be used as an independent DCS/TDCS or as a subsystem of DCS/TDCS;

(6) Mainly used for sequence control in industrial processes, the new PLC also has closed-loop control function.
