1、疑似模拟量输出板卡问题，用万用表测量4-20mA输出信号，信号是正常的!
2、开始怀疑是变频器控制信号输入端有了问题，换了一台同型号变频器，问题仍然如此。
3、用一台手持式信号发射器做4-20mA输出信号源，输出标准电流信号至变频器，这下变频器启动了，因而我们排除了模拟量输出板卡和变频器的故障。
4、由此推测是变频器的干扰信号传导至模拟量通道所致。
5、为了验证，在PLC模拟量4-20mA输出通道中加装了一台信号隔离模块TA3012，TA3012的输入端子5、6接模拟量输出模块，输出端子1、2端子接变频器，3、4端子接外部24VDC供电电源，变频器正常启动了。
6、据此断定，问题的根源在于变频器干扰模拟量通道所致。

目前，亚马逊电商平台也在利用碳信托提供的碳标签打造“climate pledge friendly（气候承诺友好型）”体系，以推动绿色消费。调研机构YouGov在2021年5月面向全球10个国家开展的消费者调查中显示，碳信托的碳标签被评为最受认可的碳标签。
碳信托中国区总裁赵立建表示，“通过第三方机构认证并获得碳标签，是企业响应国家“双碳”目标，展示自身碳减排努力并获得消费者信任的有效工具。此次与国内认证机构中标合信进行合作，相关认证既符合国内政策要求，也能帮助企业获得国际市场的认可，有利于国际国内标准的互联互通和国际合作”。作为中国最早开展节能低碳技术服务和评价的权威认证机构，中标合信总经理李铁男表示，“与具有国际公信力的碳信托合作，有利于双方更好地满足国内外客户对可持续相关的认证需求。随着国内对碳中和的重视不断增加，碳标签将帮助中国企业提升在国际上的竞争力，也将帮助国际品牌更好地深耕中国市场，并引领供应链的绿色升级”。碳信托长期专注于帮助企业客户对产品碳足迹进行测算、管理和减排，此次在中国市场推出的碳标签包括碳足迹、减碳、低碳和碳中和以及低碳包装、碳中和包装六种。这意味着，企业在开展碳测算、减排路径规划等一系列减排措施后，如果符合相关标准，就可获得由碳信托和中标合信颁发的认证及证书和对应碳信托碳标签。其中，碳足迹标签的获取，需要企业或产品的碳核算符合ISO14067或PAS 2050标准；减碳标签则需要企业在碳足迹标签的基础上，通过减排行动降低了产品碳排放，并得到中标合信与碳信托的认可；低碳标签对应的是，在碳足迹标签的基础上，企业能够证明产品比市场同类产品或可以替代的产品碳排放更低；碳中和标签显示的是，依照国内碳中和相关指南和PAS 2060等国际标准，企业在产品、机构、活动碳核算的基础上，经过减排后仍有剩余排放，这部分通过购买森林碳汇等碳抵销额度把剩余的碳排放进行抵销，从而实现碳中和。与碳信托在认证与碳标签领域合作多年的知名品牌依云（达能集团旗下），长期开展减碳行动，谈到减碳的话题，达能全球市场总监Aurelia RABIN表示：“气候变化愈发受到关注，依云也在进行着包括碳足迹测算、减排及碳抵消等一系列减碳的举措；我们与低碳领域专业机构碳信托进行合作，对减排行动进行了认证，并通过碳信托的碳标签，帮助我们向消费者更清晰地传递如何将低碳贯穿在产品的生产环节中，并助力提升我们在可持续发展方面的公信力以及品牌美誉度。而与碳信托长期合作的知名包装厂商利乐包装，也十分认可碳信托在低碳领域的价值。利乐包装全球环境总监 David Cockburn分享到：“我们的客户对可持续发展十分重视，并通过一系列的举措，努力减少对环境的影响。同时，通过与认证机构碳信托在认证与碳标签的合作，利乐包装可以更好地与客户一起积极践行着可持续发展的理念并付诸行动。”
总体而言，碳标签展示的是产品“从摇篮到坟墓”整个生命周期的碳足迹，为全面、科学评估产品碳排放的重要方式，有利于政府、企业和消费者更直观地了解一个产品的碳排放信息。
因此，对政府来说，碳标签将为政策制定与相关举措的出台提供科学的参考，让政府在采购时选择更多的低碳产品，并为低碳产品提供更精准的优惠政策。从消费者的购买角度来说，消费者通过碳标签能清晰了解产品的碳排放信息，在选购绿色产品时就能有据可依，做出的低碳购买行为则将进一步倒逼企业的减碳行动。
上述调研机构YouGov的全球调研还发现，62%的中国消费者更倾向购买印有碳标签的产品，同时有60%的消费者倾向于购买价格更高、印有碳标签的产品。

Carbon label is an important way to show the carbon footprint of certified products in the form of labels on product packages, so as to make the carbon footprint of products transparent. In the second half of 2021, China's textile and clothing, consumer goods, electrical appliances manufacturing and other industries have begun to promote the work of carbon labeling. Facing the emerging market, carbon labeling services need more internationally recognized professional institutions to participate. Carbon Trust is a professional carbon neutrality consulting organization headquartered in London, UK. It participated in the preparation of thABB可控硅5SHY3545L0014、PPA322B HIEE300016R2 HIEE400235R1、KUC755AE105 3BHB005243R0105、DSDP140Ae world's first product carbon footprint standard PAS 2050 as early as 2007, and launched the world's first carbon labeling system in the same year. Up to now, the carbon labels provided by Carbon Trust have been used in 27000 products in more than 40 countries around the ABB可控硅5SHY3545L0014、PPA322B HIEE300016R2 HIEE400235R1、KUC755AE105 3BHB005243R0105、DSDP140Aworld. Brand enterprises using carbon trust carbon labels include Nestle, Danone Group, LG Electronics, Dyson, Tetra Pak, Kia automobile, etc.
At present, Amazon e-commerce platform is also using the carbon label provided by Carbon Trust to build a "climate pledge friendly" system to promote green consumption. According to the consumer survey conducted by YouGov, a research organization, in May 2021 for 10 countries around the world, the carbon label of Carbon Trust was rated as the most recognized carbon label.
Zhao Lijian, President of Carbon Trust China, said, "to pass the certification of a third-party organization and obtain a carbon label is an effective tool for enterprises to respond to the national" double carbon "goal, demonstrate their carbon emission reduction efforts and gain the trust of consumers. This time, we will cooperate with the domestic certification authority Hexin. The relevant certification not only meets the requirements of domestic policies, but also helps enterprises obtain the recognition of the international market, which is conducive to the interconnection and international cooperation of international and domestic standards. ". As the first authoritative certification body to carry out energy-saving and low-carbon technology services and evaluation in China, Li Tienan, general manager of win Hexin, said, "Cooperating with the carbon trust with international credibility will help both parties better meet the sustainable certification needs of domestic and foreign customers. With the increasing emphasis on carbon neutrality in China, carbon labels will help Chinese enterprises improve their competitiveness in the world, and will also help international brands better cultivate the Chinese market and lead the green upgrading of the supply chain". Carbon Trust has long focused on helping enterprise customers calculate, manage and reduce their carbon footprint. The carbon labels launched in the Chinese market this time include carbon footprint, carbon reduction, low carbon and carbon neutralization, as well as low carbon packaging and carbon neutralization packaging. This means that after carrying out a series of emission reduction measures such as carbon measurement and emission reduction path planning, enterprises can obtain the certification and certificate issued by Carbon Trust and bid winning Hexin and the corresponding carbon label of Carbon Trust if they meet the relevant standards. Among them, the acquisition of carbon footprint labels requires that the carbon accounting of enterprises or products comply with iso14067 or PAs 2050 standards; Carbon reduction labels require enterprises to reduce carbon emissions of products through emission reduction actions on the basis of carbon footpABB可控硅5SHY3545L0014、PPA322B HIEE300016R2 HIEE400235R1、KUC755AE105 3BHB005243R0105、DSDP140Arint labels, and obtain the recognition of the bid winning Hexin and Carbon Trust; Low carbon labels correspond to the fact that, on the basis of carbon footprint labels, enterprises can prove that their products have lower carbon emissions than similar products or replaceable produABB可控硅5SHY3545L0014、PPA322B HIEE300016R2 HIEE400235R1、KUC755AE105 3BHB005243R0105、DSDP140Aguidelines for carbon neutralization and international standards such as PAS 2060, enterprises still have residual emissions after emission reduction based on the carbon accounting of products, institutions and activities.

In general, the carbon label shows the carbon footprint of the whole life cycle of the product "from cradle to grave". It is an important way to comprehensively and scientifically evaluate the carbon emission of produABB可控硅5SHY3545L0014、PPA322B HIEE300016R2 HIEE400235R1、KUC755AE105 3BHB005243R0105、DSDP140Acts, which is conducive to the government, enterprises and consumers to understand the carbon emission information of a product more intuitively.
Therefore, for the government, carbon labeling will provide a scientific reference for policy formulation and the introduction of relevant measures, so that the government can choose more low-carbon products when purchasing, and provide more precise preferential policies for low-carbon products. From the perspective of consumers' purchase, consumers can clearly understand the carbon emission information of products through carbon labels, and can have a basis when purchasing green products. The low-carbon purchase behavior will further force enterprises to take carbon reduction actions.
The global survey conducted by YouGov, the above-mentioned research agency, also found that 62% of Chinese consumers prefer to buy products with carbon labels, while 60% of consumers prefer to buy products with higher prices and carbon labels.
