Title:
SINGLE SIGNAL TRANSMISSION OF SAFETY-RELATED PROCESS INFORMATION
Document Type and Number:
Japanese Patent JP2008276792
Kind Code:
A
Abstract:
To provide a measure related to transmission of a safety process signal between an input unit and an output unit of a safety system, and in particular, a measure for enabling transmission and, by extension, processing of safety process information extremely easily.
In order to transmit safety process information, a plurality of process signals (S211-S212, S221-S222 and S100) redundantly detected for identifying a safety-related event of a system are converted into single process signals (S1 and S110) for the purpose of subsequent processing of the system base.
