Principles of Safety Communication (POSC)

The communication system is based on serial data transfer and used in 
industrial automation or process control applications. Implementation 
of a functional safety communication profile in a standard device is 
not sufficient to qualify this device as safe. The necessary measures 
to achieve the risk reduction of fault avoidance and fault control 
require a definite design of safe communication system. However, safe 
communication via a bus does not ensure on its own that the 
transferred safety-relevant function is also safe. The information 
must be produced and processed safely. 
Safety communication layers which are implemented as parts of 
safety-related systems according to IEC 61508 provide the necessary 
reliability in the transfer of messages (information) between two or 
more participants on a network in a safety-related system as well as 
a reliability regarding the safe behaviour in case of network failures. 
Safety communication layers specified in IEC 61784-3 provide this so 
that a network can be used for applications requiring functional safety 
up to the Safety Integrity Level (SIL) specified by its corresponding 
functional safety communication profile. 
This workshop discusses reliable communication systems to functional 
safety, detection of failures such as repetitions, losses, inclusions, 
wrong sequences, data corruptions, or delayed messages between safety 
and not safety data. For this, in addition to appropriate test procedures, 
different network topologies will be realised. In addition to Unicast, 
Multicast-communications are also possible, and in addition to 
conventional Master-Slave- also Slave-Slave-connections. The data 
exchanged between two safety-participants will be encapsulated, i.e. 
both terminals of a connection guarantee the safety integrity. The 
transport layers will be called "Black Channel".
