This article will describe the PLC market growth in last decade. According to Frost & Sullivan study that announced in Januari 1995 on the PLC market. According to this study the revenues of world-wide PLC-market would grow from USD 4.2 billion in 1993 to USD 8.6 billion in the 2000. This means the annual growth rate is 10.8%. If calculated in the units number, there is an raise from 8 million units in 1993 to around 18 million units in 2000. This means the annual growth was around 12.3%, and it was higher than the growth in revenues.
The significant increasing of software is also showed that revenues of software are supposed to raise from 9 - 12% over the same period. The major growth industries stated are the pulp and paper, chemical, automotive, food and beverage, wastewater management, pharmaceutical, metal, electronics and medical. The grade in 1992/1993 with value to revenues are:
1. Micro PLC
• Siemens, Allen-Bradley, Mitsubishi, GE Fanuc, Omron
2. Small and Medium PLC
• Siemens, Omron, GE Fanuc, Mitsubishi, Allen-Bradley
3. Large PLC
• Allen-Bradley, Siemens, Modicon, GE Fanuc
4. Fault Tolerance PLC
• Triconex, August, Triplex
5. PLC monitoring and interface SW
• Wonderware, Heuristics (Onspec) and Laboratory Technologies, Iconics, Intellution, US Data,
More than a decade after that in 2007 to 2012, the worldwide PLC market will grow at 6.5% over the five years from nearly USD 9.0 billions in 2007 to more than USD 12 billions in 2012, according to ARC that already published in 2007 saw the high growth in Asia and Eastern Europe and, while a period of cooling-off is estimated, the demand of automation is projected to maintain to grow during the estimate period. ARC was identified rising demand for PACs (programmable automation controllers) able of providing motion, real-time logic, and process control mutually with HMI and other single platform functions. It looks PLC-based PAC market development surpass overall market of PLC growth with major suppliers expanding PLC functions ahead of pure logic, especially in models of higher end. Mainly currently large and small PLCs and the some micro PLCs will move into PACs, with pure PLCs fitting limited to the lower micro and nano level PLC. It concludes, are set for enlargement across sectors of process, discrete, and hybrid as suppliers respond to the requirement to increase productivity while reducing consumption of energy.
According to GlobalData's in PLC Market for Power Plants Thermal in Global Market Size Analysis to 2020, gives comprehensive information on the market of Global PLC and gives historical and numbers of forecast for volumes, revenues, and average charge up to 2020. This coupled with benchmarking of competitiveness to the top market contributors gives the detailed market's competitive scenario of understanding. The market of Programmable Logic Controller (PLC) has been comprehensively forced by the global economic meltdown, which has produced in a slow rate of growth over the past two years. There has been dropped in the market of PLC revenues from 2008 due to decreasing in the investments of capex. The market is well merged, as share of market in surplus of 79% is held by the top 4 manufacturers, they are Schneider Electric Corporation, Siemens AG, Mitsubishi Electric Corporation, and Rockwell Automation, Inc. The others manufacturers are contributed around 20% from the total market, they are such as, GE-Fanuc, Omron Electric Corporation, Toshiba America, Inc., and other manufacturers are present. Original builders of equipment manufacturers or machine are some of the main PLC end-users, but the drop in correlated costs due to lack of development projects across the world has led to a turn down in the growth rate of industry.
