Control and communications system including an engineering unit

摘要

A system (30) control and communication that includes several automation units (32, 50, 52) which are adapted to process signals in planes corresponding functions (38, 42) within the automation unit (32, 50, 52) and which are connected at the same level to a common communication bus (36) to provide communication of peer to peer between the automation units (32, 50, 52) further including an engineering unit (34) which is connected to the communication bus (36) and which is adapted to provide the functions that allow at least one automation unit (50) to exchange signals (40) to another automation unit (52) wherein the handshaking signals (40) will be used in processing of a function plan (42), wherein the engineering unit (34) is adapted to provide a list (48) of said signals (40) that must be received by the other unit Automation (52) when at least one automation unit (50) attempts to exchange point (40) to the other automation unit (52).
