Abstract: A method for the transmission of data via an Inter Communication Link (ICL) to a receiver unit is provided. The method identifies data to be transmitted in a memory cell of a data storage. The method continues by extracting the address of the memory cell and extracting the data word from the identified data. The method continues by calculating a CRC (cyclic redundancy check) checksum from the extracted address of the memory cell and the extracted data word. The method continues by generating a data packet to be sent by appending a start frame delimiter and a stop frame delimiter to the extracted address of the memory cell, the extracted data word and the calculated CRC checksum. The method continues by sending the data packet.

Abstract: A network module for sending and/or receiving of data packages from a network arrangement located in a network with ring structure, wherein the data package includes at least one data package segment, a source address, a destination address and an identification number. The network module includes a first network interface and a second network interface, for receiving and/or sending of data packages via the ring structure, a processor configured to determine, based on the destination address, if data packages received are directed to the network module and to determine if the source address and/or the destination address are contained in a predefined list of the network participants, to determine, based on the source address and the identification number, if a copy of a data package directed to the network module is already created in a memory, to create a copy of the data package in the memory.
