PLC市场的健康曾经是I / O市场增长的重要因素,因为PLC I / O模块是最大的部分。但是,2013年,虽然PLC市场继续下降,但I / O市场增长。一方面,这种增长主要来自其他类型的I / O类型,如DCS I / O和基于PC的I / O,它们主要用于稳定或更快的增长行业。相比之下,PLC I / O的离散行业主要用于市场波动更容易受到影响。另一方面,考虑到PLC市场在2013年继续下降,而对于PLC I / OS而增长,虽然人们不愿意在不确定的时间内建造新的控制系统,但无法将扩展,升级和维护的需求永远克制它们对于保持现有的系统功能是必不可少的,或者甚至可以改善它们。
虽然离散的行业尚未做得很好,但汽车行业是I / O模块的最大离散行业之一,这一直保持商机为I / O供应商提供商机。汽车行业对工业自动化供应商一直很重要的汽车需求,高度自动化和支持。然而,这个行业的机会很可能会放缓。近年来,汽车行业建设新产能的投资一直强劲,特别是在新兴地区,被认为具有低劳动力成本,有利政策和市场潜力。但投资一直如此强大,即现有,规划和施工的生产能力较少潜在的进一步扩展和新建筑。随着经济局势停滞不前,市场需求不太可能蓬勃发展。预计,将来,对汽车行业的I / O模块的需求将主要是为已安装的生产基地服务。
Comparatively stable, process industries have been an important factor to offset the weaker growth of the discrete industries and to make the total I/O market grow. Of the process industries, oil and gas has been no doubt an important sector to drive growth, not only because of its stable downstream needs, but also because of exploitation of unconventional sources. The unconventional boom has led to many new construction projects in oil and gas; and has also helped growth in associated industries like refining, petrochemicals and chemicals, as now they have cheaper and handier feedstock and they may also need to improve their processes for unconventional oil and gas. All of these factors have however mainly applied to North America. The recent price slump of crude oil, which reflects a change in the supply-demand balance, puts at risk the strong investment on oil and gas. If oil supply grows faster than demand, the oil price may remain at a relatively low level, which will somewhat affect investment.
像石油市场一样,虽然需求正在降低,但对于I / O供应商来说,更为重要的是,保持甚至增长他们的市场份额。一个停滞不前的市场迫使供应商和客户们要更加关注节能成本,这将加速I / O产品的演变。为了处理不同类型的信号,不同的应用和不同的网络,也有各种版本的I / O模块,甚至由单个供应商提供。这肯定满足各种需求,但同时可以更难以处理安装,维护和备件管理。最近发布的I / O模块越来越具有整体成本节省的功能。例如,通用I / O模块与支持各种类型信号的I / O端口,不仅由PLC I / O供应商发布,但最近已成为DCS I / O供应商的趋势。它有助于最终用户降低布线等成本,简化设计,安装,维护和备件管理。一些公司还致力于将产品集成到统一平台上的设计中。因此,他们可以提供更少的选择来满足更多客户需求,这反过来帮助客户使用这些模块简化工作,以及帮助供应商从设计中降低成本。但是,这并不意味着每个供应商都试图为所有人提供一个模块。 Many suppliers have their targeted industries; and, using their industry expertise, they are also including in their I/O modules features favored by these industries, if not widely favored by the general market, This is being done not only by the specialist suppliers, but also some system suppliers have included this into their strategies.
