hi buddies,
can somebody guide me about monitoring plc function in tnc155.there is a tracing function for these controllers but when i call it,i can't command cnc to do something as i am tracing it(for example how can i send a S1000 command when the tracing function is active?)
regards.

Have you read the manuals which are available from the Heidenhain website?

i have the manual,and i know about tracing the plc program ,and i have done that,but if you've noticed i asked that how can i trace the plc program while i am sending the commands like S,M,T to controller to monitor the signals when these commands are executed.if you have used the tracing function you have seen that you cant use the controller keypad for sending the commands and when you use the keys (e.g T) the cnc sends the key non functional message.
anyway thanks to your reply and i am still waiting an answer for my question.
