ASE 2000 communication test set is a simulator to simulate some control protocol, it's trial version is free for 30 days. This tool is awesome except the not user friendly GUI and minimal user guide. Here i will explain the detailed how to simulate iec 60870-101 protocol using ASE 2000. FYI, i use brodersen RTU as iec-60870-101 slave and i will use ASE 2000 in my laptop as iec 60870-101 master

1. click properties - communication, In the channel tab make sure that you have right com port setting. In the Line tab chose constant as the carrier option, make sure the baud rate is same with your RTU/PLC setting.

2. Click Properties - Protocol Specific, In The Channel exchange defaults make sure that the DL address and Comm address' value is same with your PLC/RTU setting. Check the Asynch and iec 870-5-101. make sure that the values in that panel are same with your RTU/PLC setting

3.  go to exchange list, here are what you need to make connection in this protocol
reset link (freq 0) (flag: display transmit)
Access Demand (freq 0) (flag: display transmit)
Interogeration (freq 0) (flag display transmit)

4. that's all. you can add more exchange list if you want. for further info you can ask me check their user manual.
