5 Compatibility with TNC 355
The flag ranges for the TNC 355 have also been used for the TNC 360 to enable PLC routines
created for the TNC 355 to be run on the TNC 360 as well.
However there are many functions that can be programmed much more simply with PLC words
with the TNC 360. PLC marker M2719 must be set to activate the strobes for word processing.

HEIDENHAIN recommend programming the PLC functions over the word range only. This makes
the PLC program easy to read and a lot shorter.
