Chinese control-system users opt for Siemens

Siemens is the most recognised and used brand of control system in China, according to a user survey carried out by IMS Research.

Almost 75 per cent of respondents said they were using Siemens products in their PLC-based control systems; this percentage exceeded nearly 50 per cent for Siemens PC-based control systems.

A recent IMS Research report on the Chinese PLC market confirms this, with Siemens found to have more than a 50 per cent share of the PLC market.

One question asked survey respondents to give what they considered the most important product attribute when specifying a control system.

Reliability and high performance were cited as the two most important factors.

Of supplier attributes, '24-hour technical support', 'existing relationship with supplier' and 'brand name of supplier' were ranked as the three most likely to be 'essential' and 'very important' factors when specifying a machine-control system.
