控制功能包括PID控制运算、前馈补偿控制运算、比值控制运算等，应根据控制要求确定。可编程逻辑控制器主要用于顺序逻辑控制，因此，大多数场合常采用单回路或多回路控制器解决模拟量的控制，有时也采用专用的智能输入输出单元完成所需的控制功能，提高可编程逻辑控制器的处理速度和节省存储器容量。例如采用PID控制单元、高速计数器、带速度补偿的模拟单元、ASC码转换单元等。

TRICONEX 8310该选择包括运算功能、控制功能、通信功能、编程功能、诊断功能和处理速度等特性的选择。

可编程逻辑控制器系统的通信网络中，上级的网络通信速率应大于1Mbps，通信负荷不大于60%。可编程逻辑控制器系统的通信网络主要形式有下列几种形式:

1)、PC为主站，多台同型号可编程逻辑控制器为从站，组成简易可编程逻辑控制器网络;

2)、1台可编程逻辑控制器为主站，其他同型号可编程逻辑控制器为从站，构成主从式可编程逻辑控制器网络;

3)、可编程逻辑控制器网络通过特定网络接口连接到大型DCS中作为DCS的子网;

4)、专用可编程逻辑控制器网络(各厂商的专用可编程逻辑控制器通信网络)。

The control function includes PID control operation, feedforward compensation control operation, ratio control operation, etc., which should be determined according to the control requirements. Programmable logic controller is mainly used for sequential logic control, therefore, most occasions often use a single loop or multi-loop controller to solve the analog control, and sometimes also use a dedicated intelligent input and output unit to complete the required control functions, improve the processing speed of programmable logic controller and save memory capacity. For example, PID control unit, high-speed counter, analog unit with speed compensation, ASC code conversion unit, etc.

TRICONEX 8310 This selection includes the selection of computing functions, control functions, communication functions, programming functions, diagnostic functions and processing speed.

In the communication network of the programmable logic controller system, the communication rate of the upper-level network should be greater than 1Mbps, and the communication load should not be greater than 60%. The communication network of programmable logic controller system has the following main forms:

1) PC is the main station, and several programmable logic controllers of the same model are the secondary station to form a simple programmable logic controller network;

2) One programmable logic controller is the primary station, and other programmable logic controllers of the same model are the secondary station, which constitutes the master-slave programmable logic controller network;

3) The programmable logic controller network is connected to the DCS as a DCS subnet through a specific network interface;

4), dedicated programmable logic controller network (dedicated programmable logic controller communication network of various manufacturers).
