    Tasks such as polling, performing control operations, and setting input or output values are done through this test software. ALIND has implemented the IEC 60870-5 Tele-control Companion Standard 103 in the ANPF 041 for communication with a controlling system. The IEC 60870-5 Tele-control Companion Standard TMW Test harness test set can be used as a communication protocol for exchanging information between Control Centre(s) (controlling station) and their substations (controlled station(s)).
