WIPO Patent Application WO/2006/030643
Kind Code:

Abstract:
A safety controller includes a function block and a mapping block. The function block executes a function inherent to the safety controller. The mapping block converts the data used in the control system among the data treated in the function block into a data format which can be directly treated by the control system and attaches a common tag to these data. Moreover, the mapping block executes calculation according to the data treated in the function block and outputs a signal instructing whether to transmit a process alarm according to the calculation result. Moreover, the mapping block attaches a common tag to this signal. Accordingly, in the control system, it is possible to recognize these data groups related to one another.
