Embedded systems are being used for monitoring and controlling of Mission Critical and the Safety Critical System through adapting proper sensing and actuating mechanisms. The embedded systems meant for monitoring and controlling the critical systems are situated in closer locations to the production systems. Communication systems are established to facilitate communication between the production system and the embedded system. The monitoring and initiation of control actions are however triggered from a remote location through a remote HOST by way of transmission of commands and arguments to the commands which are to be learnt, understood and implemented by the embedded systems. Embedded systems that are connected to mission and safety critical streams should never be shutdown due to the mission and critical nature of the Production system. Any change needed to be done to the embedded systems must be done dynamically. The Embedded system thus must be adaptable to the changes dynamically. The command language interface between the remote HOST system and the embedded system can keep changing either due to the reasons of add-ons or upgrades. The changes needed must be adapted dynamically without the need for shutting down of the embedded systems due to the criticality reasons of the production system. This paper proposes architectures that are suitable for achieving the syntax evolution of the embedded systems for dynamic adaption.
