<p>四楼的朋友对HONEYWELL的理解有出入.</p><p>LON协议和通讯速度每个厂家只要是遵循LONMARK标准就是一样,和生产厂家没关系.否则就不是LON了.HONEYWELL 的XL500和XL50都可以做全LON的设计,完全遵循LONMARK标准. 而具我所了解INVENSYS的一些产品是LON的通讯协议,却没LONMARK标记.</p><p>HONEYWELL C-BUS的通讯速度是可设定, 你可以设高,也可以设低.</p>

<p>四楼的朋友:</p><p>1.据我所知,一条LON-BUS不加中继或路由器,只能带64个lon模块,不知道你的127如何计算出来的?而且在实际工程中,一般建议每段lon-bus30-40个lon模块,这样速度才有保证.</p><p>2.你似乎比较推荐lon-bus,但你要知道honeywell也是可以走纯lon架构的,但事实摆在眼前,honeywell纯lon的项目,很多大项目调试起来都比C-bus架构复杂,而且运行效果不如理想.相反C-BUS架构还是比较稳定,调试方便.</p><p>3.不知道INVERSYS做lon系统,是否比honeywell优胜?优胜在哪些方面?</p>

真搞不懂Honeywell搞出这么多通信协议来干什么,又是C-bus, 又是E-bus, 同一个系统中, DDC和DDc之间用C-bus, DDC-和VAV控制器又得用E-bus,事情越搞越复杂。 知道为什么吗?因为VAV控制器是从别的厂家买来的,为了和Honeywell 自己的DDc通信,不得不又开发出一套E-bus。

siemens的系统挺稳定的,我接触一个项目,用旧型号的系统,rcu等,用了10多年了,现在我们办他们升级,而且升级也很方便.
