Posted 17 Oct 2012 Fun Fun. I am stuck using Sinaut because of data buffering. It is connected to the end of my small S7-300 rack. This is a remote pumping station and transmits data over radio by means of a MDS Transend 900 (GE). The sinaut module is what connects my S7-300 to the radio. The sinaut protocol is not necessary. I have an ethernet port on the S7-300 as well as a serial port that can connect directly to the radio, but because of that data buffering and frequent temporary loss of communication (over radio), I have to go through the sinaut module (most expensive module in my cabinet). Any alternate suggestions? Anyone heard of Esteem Enlace Ethernet and radio? Saw it in an application for field irrigation but can't find info on it. Thanks in advance!
