1. A method for communicating with at least one field device utilizing an interface device, each field device being connected to a communication channel of the interface device, the method comprising:
a) receiving a first command associated with a first field device from an industrial device;
b) communicating with the first field device over a first communication channel to execute the received first command, said communicating comprising performing a check, by the interface device, to determine whether the first communication channel is free and synchronizing the interface device to the first communication channel prior to communicating the first command to the first field device;
c) receiving at least one command associated with the at least one field device, at least one command including at least one command associated with a second field device from the at least one field device;
d) caching the at least one command in a memory module prior to execution of the first command; and
