5.3.2 PLC Error Messages

The TNC 407 and TNC 415 contain dedicated files for error messages in the first dialog language and
for English error messages. File .EE1 (.ER1) or file .EEE (.ERE) is accessed depending on machine
parameters MP7230 (dialog language) and MP4010 (PLC program from RAM or EPROM). (See "PLC
Programming" Register, Chapter 1.3).
This means that, to select the appropriate error message, it is no longer necessary to interrogate the
dialog language with PLC marker M2041 as was the case with the TNC 355.
PLC marker M2041 has no function in the TNC 407 or TNC 415.

5.3.3 Mode Code

The code for the "Programming & Editing" and "Test Run" modes is no longer displayed because a
foreground and a background mode can be active in the TNC 407 and TNC 415 at the same time.
