The files are divided into text blocks. Each text block can contain up to 10 lines,
each with 60 characters. It is ended with <FF>. On the TNC you can enter an
<FF> with the key combination SHIFT + RET. Through the error number (line
number) in the PET table, the TNC finds the associated text block in the “error
correction” and “error cause” files. Error number zero is the first text block.
The error number is also shown in the heading of the help window.
With the PLC programming software PLCdesign, you can generate a PET table
and text files, and then transfer them to the TNC.
In the PLC you can use markers M4220 to M4222 to interrogate the activity of
an error from the PET table.

When the PLC pop-up window is called, other pop-up windows (e.g. help
window) are put into the background and become active again after the PLC
pop-up window has been closed. The PLC pop-up window can be displaced to
the background by another pop-up window.
The module does not return until the pop-up window is closed. It must be
called in a spawn job, not in a submit job, because otherwise the subsequent
submit jobs will not be run until the pop-up window is closed.
