摘要
主要介绍了PLC联网的应用,建立1个局域网控制各个车间的空调,保证各个车间的温湿度。在整个系统中信息的处理、传送是关键所在,上位机、主站、子站之间的通信以及外围接口的应用在本文有详细的介绍。本文介绍的PLC联网在空调系统中的应用,选用的硬件部分全是三菱系列产品,这也充分体现了PLC的网络通信的智能化。随着科学技术不断的飞跃发展,PLC也不断得到完善和强大,同时它的功能也大大超过了逻辑控制的范围,如联网通信功能和自诊断功能等。而且PC机的加入更加完善了网络的可靠性。
This text primarily introduces the PLC net application, establishes a bureau net to control the air conditioner of each workshop, guaranteeing the degree of humidity, of each workshop. In the whole system, the handle, delivering of information is the key, the application of the communication and the application of outer makes a detailed introduction in this text. The paper introduces the hardwares of PLC net in the air condition in the system, which are all Mitsubishi series products, this also reflects PLC intelligence. Along with the science technique continuous development, the PLC also eonfinuously get perfect with strong, at the same time its function also consumedly exceeds the logic scope control, such as net eorrespondenee function and the diagnosis function etc., and with the PC machine affiliation the net is more perfected the network reliability.
