In industrial automation and electrical substation systems, communication stability is everything. The IEC 60870-5-104 (IEC 104) protocol serves as the backbone for telecontrol telemetry across TCP/IP networks. When developers and automation engineers look to interact with telemetry hardware or cellular modems (like robust RTUs or industrial DTUs) that route this data, they often must execute specific configuration routines. write at command station v104 high quality
