Statement for IEC60870-5-104

Both Slave and Master source code feature are detailed as below.

ü All data objects and request-response procedure of IEC60870-5-104 are implemented except for file transmission.

ü All data in realtime database are monitored to be encoded many different frames by the different COT.

ü The source code is easy to be embedded to substation or power t&d scada.

ü The source code is compatible to IEC 60870-5.

ü With the source code, many SCADA system can be easily inter-operation.

ü User are quickly grasp the source code referring to the DEMO.
