控制器。随着LOGO!OBA6系列控制器以及LOGO!TD文本的出现，完美的解决了这一问题。从而在很多通过LOGO！控制器可以达到控制要求，却因为LOGO!人机界面不友好等因素而选择PLC控制器的控制系统也出现了LOGO!以及LOGO!TD的身影。
    一提到暖通系统的控制，大家首先想到的就是采用DDC控制，RWX系列和RWD系列DDC控制器的风靡一时也印证了这一点。然而DDC控制器存在，功能单一，针对用户操作的人机界面不够友好，逻辑控制能力不足等问题。使其在应对很多暖通系统的控制时有点鸡肋的感觉。就以我将要介绍的系统为例，通过2个单回路DDC加以延时继电器等继电系统也完全可以实现控制功能，但是对于制造商增加了继电器线路部分，无形中就增加了故障点；并且一般通用控制器都不会有中文界面，对于用户而言，对操作人员的要求也会相应的要求更高，无形中提高了用户的人力成本。       在暖通控制系统中，PLC控制系统也应用广泛，尤其是低端的PLC控制系统（如S7-200）。但是由于暖通控制的特殊性，一般点数较少，控制相对简单，特别是单一系统，即便采用1低端的PLC控制器，也有点大材小用的味道，其性价比肯定不是1好。       LOGO! OBA6控制器，主模块集成4路AI。一般的暖通系统中，无非控制温度，湿度，压差，风量等参数，对于单一的系统，其AI点数都集中在1～4个点之间，因而在配置模块时无需另配模拟量模块。同时LOGO!控制器还有标准型和经济型的模块可供选择，在选用LOGO!TD做人机界面时，便可选经济型的主控模块。极大的降低了成本，提高了产品的市场竞争力。       综上所述，在暖通控制系统中，LOGO!控制器将是主控制器的1。

controller. With the logo! Oba6 series controller and logo! The emergence of TD text perfectly solves this problem. Thus in many through LOGO! The controller can meet the control requirements, but because of the logo! The control system that chooses PLC controller due to unfriendly man-machine interface and other factors also appears LOGO! And logo! TD's figure.
When it comes to the control of HVAC system, the first thing we think of is to use DDC control. This is also confirmed by the popularity of RWX series and RWD series DDC controllers. However, DDC controller has some problems, such as single function, unfriendly man-machine interface for user operation, insufficient logic control ability and so on. It makes it feel a bit weak when dealing with the control of many HVAC systems. Taking the system I will introduce as an example, the relay system such as time delay relay through two single circuit DDCS can also fully realize the control function, but for the manufacturer to add the relay line part, the fault point is virtually added; And the general controller will not have a Chinese interface. For users, the requirements for operators will be higher, which virtually increases the user's labor cost. In HVAC control system, PLC control system is also widely used, especially the low-end PLC control system (such as S7-200). However, due to the particularity of HVAC control, there are generally few points and the control is relatively simple. Especially for a single system, even if the lowest end PLC controller is adopted, it is a bit overqualified and underused, and its cost performance is certainly not the best. LOGO!  Oba6 controller, the main module integrates 4-way AI. In the general HVAC system, there are no parameters other than temperature, humidity, differential pressure and air volume. For a single system, the AI points are concentrated between 1 ~ 4 points, so there is no need to configure another analog quantity module when configuring the module. At the same time, the logo! The controller also has standard and economical modules to choose from. Logo is selected! When TD is used as man-machine interface, the economical main control module can be selected. It greatly reduces the cost and improves the market competitiveness of products. To sum up, in the HVAC control system, logo! The controller will be the primary controller.
