orders for digital industries declined due to lower demand in the short-cycle factory automation and motion control businesses which faced increasingly adverse market conditions during the course of the fiscal year particularly in the automotive and machine building industries .
these declines were only partly offset by clear growth in the process automation business and a moderate increase in the software business which was due to positive currency translation effects and new volume from recent acquisitions particularly including mendix .
the latter two businesses were also the drivers for revenue growth as year-overyear revenue growth for the short-cycle businesses in the first half of fiscal 2019 gave way to declines in the second half .

the automotive industry was hit by production cuts in europe and weak demand in china .
this among other factors also impacted the machine building industry particularly affecting customers in germany and japan .
production growth in the pharmaceutical and chemicals industries flattened during the course of fiscal 2019 due in part to spillover effects from the automotive industry on related chemicals segments .
the food and beverage industry grew modestly and global electronics and semiconductor production expanded but prices were under pressure .
for fiscal 2020 the market environment for digital industries is expected to weaken further .
manufacturing investments are expected to decrease at least moderately but then begin to stabilize in the second half of fiscal 2020 .
an overall decline in investment sentiment caused by global trade tensions among other factors dampens short-term expectations and fuels increasing cautiousness for investments globally .
a weakening of growth in china could lead to spillover effects in other asian countries and also in europe .
