Statement  for  IEC60870-5-101

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

 

ü         All data objects and  request-response procedure of IEC60870-5-101 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.

When using an unbalanced link layer,the following ASDU types are returned in class 2 messages(low priority) with the indicated causes of transmission:

 

Type identification                       Cause of transmission

      9，11，13，21                        　　　　　　<1>

<2>

 

In response to a class 2 poll ,a controlled station may response with class 1 data when there is no class 2 data available.
