To be specific, I am thinking if I/Os of an RTU are having direct interface (one to one) with the Hart field devices then it is very handy for remote maintenance.
But what I have found is, more or less companies give RTUs having HART I/O compatibility using multi drop communication method and not direct one to one connection.
Can any one suggest me the manufacturer of such RTUs Please?
Thanks.
