Safety communication system
First Claim
1. Safety communication system in a automation application (5), comprising a first communication bus (19) on which at least one first safety monitor (12) is connected fitted with several outputs (13) controlled by the first safety monitor (12), a second communication bus (29) on which are connected a second safety inputs module (25) fitted with several inputs and capable of generating on the second communication bus (29) a second safety signal representative of the state of said inputs, and a second safety monitor (22) receiving said second safety signal and fitted with several outputs (23) that can be controlled by the second safety monitor (22) as a function of said second safety signal, characterised in that outputs (13) of the first safety monitor (12) are connected to inputs of the second safety inputs module (25) so as to control at least one output (23) of the second safety monitor (22) as a function of the state of the outputs (13) of the first safety monitor (12) connected to the inputs of the second safety inputs module (25).

Abstract
The invention relates to a safety communication system in a automation application (5), comprising a first communication bus (19) on which at least one first safety monitor (12) is connected fitted with several outputs (13), and a second communication bus (29) on which are fitted a second inputs safety module (25), capable of generating a second safety signal, and a second safety monitor (22) receiving said safety signal and fitted with several outputs (23), on the second communication bus (29). Outputs (13) of the first safety monitor (12) are electrically connected to inputs of the second inputs module (25) so as to control at least one output (23) of the second safety monitor (22) as a function of the state of the outputs (13) of the first safety monitor (12).
