In recent years this has become more difficult, thanks primarily to the advancement of the microprocessor, which has allowed the technologies to merge. With the trend toward flexible manufacturing in industry, many of the applications in the process industries now share the requirements traditionally thought to be exclusive to either DCS or PLC. These hybrid applications typically require a process control system that can deliver both PLC and DCS capabilities. Thus understanding the merging of PLC and DCS functionality is important for selecting the best system for your company. In this white paper, we will shift away from some of the classic stereotypes of DCS and PLC , such as those shown in Table 1 on page 9, in order to explore seven key criteria, which will help your company select the system that best meets your goals.
