communication problem

[kenobe]

 ???I have a T100MD 888 plc and using Tserver 3.0
I activated the server and key in 'IR*" in the command window and get reply IR1*
so now I run the TL6Launcher and  try to login in to the TLserver
I check the radio button of localhost -127.0.0.1.9080 and press Detecd ID
What I was trying to do is to connect to the PLC so that I can download my program.
but I get a popup window of title " No Response from controller"
the window displays
 " Please check the following:
1. only one PLC is conneceted to server.
2. power to the plc has been turned ON.

I check both conditions and ensrue the power is on , the com1 cable is connected proberly and of course , I use only ONE PLC.

This communcation problem troubled my very much, can the support pls help?

If you send "IR*" command from TLServer, you should receive "IR01*" from the PLC. If you are receiving something else, then the PLC could be sending out data from the serial port and interfering with the host communication from TLServer.

You can set DIP switch #4 ON, turn off and then on power to the T100MD888+. Then change the COM port settings to 9600 and try to communicate with the PLC again. If it works, transfer a blank program to the PLC then turn off DIP switch #4, set TLServer back to 38400 and everything should work now. Check your original program to see where it is causing problem.

The DIP switch is mentioned in Chapter 1 section 1.10 of the User's Manual.
