Machine safety is one of control system technology’s main areas of use. The protection of people takes top priority in mechanical engineering. PC-based measuring systems are not permitted by employer’s liability insurers on safety grounds. Unlike control systems, PCs do not adopt a predefined state in the event of a fault. It is thus, for example, the job of the safety PLC in the emergency stop circuit to deprive a machine of all kinetic energy within the shortest time possible.
Standard process control
The basic module of automation
Control system technology is essential in all cases of standardized process control. Assembly plants and painting automation are good examples of this. It is only in the case of test systems that PC-based measuring technology prevails. POMA Systems uses, amongst others, Siemens SIMATIC STEP 7 and Beckhoff TwinCAT.
